What is a landline number? A landline number is tied to a fixed-line network, like traditional home or office phones. It connects to the Public Switched Telephone Network (PSTN) using physical cables to transmit voice communication, unlike mobile phones that rely on radio signals and cell towers.

For businesses, landlines offer clear call quality and reliable emergency services. However, with mobile phones and internet-based calling on the rise, understanding the pros and cons of landlines is essential in today’s communication landscape.

How do landline numbers function?

What is a landline number, and how does it work in practice? While landlines may seem dated in a world dominated by mobile phones and VoIP systems, they remain highly reliable. Here’s a breakdown of how they function:

1. Voice Transmission: When you make a call on a landline, your voice is converted into electrical signals, which travel over the physical wires (copper or fiber optic cables) to reach the recipient. This conversion ensures that the voice remains clear and intelligible, unaffected by issues like weak signal strength.
2. The PSTN: The landline’s connection to the Public Switched Telephone Network (PSTN) ensures that the voice data is transmitted through a network of switches and cables, allowing communication between different locations globally. This network has been the backbone of telecommunication for over a century, providing a stable, reliable way for people to connect with one another.
3. Direct and dependable: Landlines are still known for their dependability. Unlike mobile phones, which rely on the health of the cellular network or internet connection, landlines can function even when there are power outages, making them a preferred choice for businesses that need constant availability. In fact, during natural disasters or widespread service disruptions, landline numbers can be the only means of communication, offering a direct and often uninterrupted line to emergency services.

What are the different types of landline numbers?

Landline numbers, though simple in concept, come with various configurations and use cases that influence how businesses and individuals interact with them:

1. Geographical area codes: Landline numbers are typically associated with a specific geographical location. Area codes identify a specific region, helping both businesses and individuals establish a local presence. For businesses, a local area code can foster a sense of community and trust with customers.
2. Local numbers: These are landline numbers assigned to a particular area. They are the most common type of landline number and are often preferred for personal communication. However, for businesses, this can sometimes be limiting, as it ties the business to a specific location.
3. Toll-free numbers: Toll-free numbers (e.g., 800, 888, 877) offer businesses the opportunity to provide a cost-free way for customers to reach them. While local numbers are tied to a specific area, toll-free numbers are not, making them ideal for companies that operate across multiple regions or need to present a nationwide presence. However, they can come with higher maintenance costs, which can be a consideration when planning your communication strategy.
4. Vanity numbers: These are customizable numbers that spell out a word, name, or acronym related to the business. For example, 1-800-FLOWERS or 1-800-PAINTING. Vanity numbers are not only memorable but can also enhance branding efforts, providing easy recall for customers.

What are the main benefits of landline numbers?

Despite the growing dominance of mobile and VoIP technologies, landlines still hold a strong position for certain use cases, especially in business environments. Let’s explore some of the key advantages:

Reliable Call Quality:

• Landline calls offer superior audio quality compared to mobile or internet-based communication.

What are the downsides of using landline numbers?

However, despite their advantages, landline numbers come with limitations, particularly as businesses look for more flexible and scalable communication solutions:

1. Limited Mobility:
   
   1. Landlines are fixed-location services, tying you to a specific place.
   2. This lack of mobility is a significant drawback for businesses with remote or traveling employees.
   3. Unlike mobile phones or internet-based communication systems, landline numbers cannot be used on the go.
2. Higher Maintenance Costs:
   
   1. Traditional landline services often incur higher maintenance costs than newer technologies.
   2. These costs include maintaining physical infrastructure and paying for long-distance calls.
   3. Businesses with nationwide or international operations may face especially high costs.
3. Declining Usage:
   
   1. Landline usage is decreasing due to the rise of mobile phones, internet-based communication, and VoIP solutions.
   2. Businesses and consumers are opting for more flexible and feature-rich alternatives.
   3. This trend makes it harder to justify the costs of investing in or maintaining landline connections.

How are landline numbers formatted?

Landline numbers, like any other phone numbers, must follow a specific format to ensure proper routing and connection. This includes several key components:

Country Code:

• Each country has a unique country code to distinguish it from others.
• Example: The United States uses the country code +1, while the UK uses +44, and India uses +91.
• When dialing internationally, the country code ensures the call is routed to the correct nation.

Area Code:

• An area code identifies a specific geographic region within a country, which is essential for routing calls accurately.
• Example: In the US, 212 is the area code for Manhattan, New York, while 408 covers parts of California, including San Jose.
• Area codes are particularly important for businesses operating in specific regions to establish a local presence.

Phone Number:

• The phone number is the unique identifier for the recipient within the specified area and can vary in length by country and region.
• Example: In India, a landline number in Delhi might look like 011-12345678, while in the UK, a London number could be 020-12345678.

E.164 Format:

• For international calls, phone numbers are standardized in the E.164 format, which includes the country code, area code, and local number without spaces or dashes.
• Example: A US number would appear as +14155552671 in E.164 format, ensuring global compatibility for dialing.

National Dialing Formats:

• Some countries use unique national dialing formats when calling locally or regionally.
• Example: In the US, local calls within the same area code might only require dialing the 7-digit number, while in India, dialing ‘0’ before the area code (e.g., 011-12345678) is mandatory for national calls outside the area.

What are 6-digit phone numbers?

Short codes, introduced by wireless carriers in 2003, were designed to meet the growing demand for efficient mass messaging. They are 6-digit numbers specifically built for high-throughput, application-to-person (A2P) messaging, making them ideal for sending critical, time-sensitive updates like authentication codes, alerts, and promotional notifications. Unlike traditional 10-digit long codes, short codes offer:

• Faster delivery: Thousands of messages can be sent per second.
• Better prioritization: Carriers prioritize short codes, ensuring high deliverability for important updates.
• Simplified user experience: Their shorter format makes them easier to recognize and remember.

How are 6-digit numbers used?

The versatility of short codes extends across multiple industries. Here are some key applications:

Retail and E-commerce:

Businesses use short codes to announce flash sales, send discount codes, and share product updates. 

Examples:

“Text DEAL20 to 123456 to get 20% off your purchase today!”

“FLASH SALE! Text SALE to 654321 for exclusive early access to our 50% off deals.”

“Sign up for SMS alerts by texting VIP to 456789 and receive free shipping on your next order.”

Healthcare:

Appointment reminders, public health notifications, and patient engagement campaigns are made seamless with short codes. Enhance patient experiences and rapport by improving healthcare communication, reducing appointment no-shows with SMS alerts, delivering time-critical emergency health services, and optimizing public health campaigns. 

Examples:

• “Your appointment with Dr. Smith is scheduled for tomorrow at 3:00 PM. Reply YES to confirm or RESCHEDULE to change.”
• “Public Health Alert: Flu vaccine clinics now open. Text VACCINE to 789123 for locations near you.”
• “Reminder: Please fast for 12 hours before your blood test tomorrow at 8:00 AM. Questions? Text HELP to 987654.”

Finance and security:

Banks and financial institutions rely on short codes for two-factor authentication (2FA) and account activity alerts. 

Examples:

• “Your account balance is $1,234.56. For more details, text INFO to 123123.”
• “Your one-time verification code is 876543. It will expire in 5 minutes.”
• “Alert: A transaction of $500 was made on your credit card ending in 1234. Text FRAUD to 456123 if this wasn’t you.”

Logistics and transportation:

Ridesharing services and courier companies use short codes for real-time updates, such as delivery status and driver notifications. 

Examples:

“Your package will arrive today between 1 PM and 3 PM. Track it here: [link].”

“Driver Alex is 5 minutes away in a blue Toyota Camry. Text SUPPORT to 654987 if you need help.”

“Your ride to JFK Airport is confirmed. Driver John will arrive at 6:15 PM. Reply CANCEL to cancel.”

What are the advantages of 6-digit numbers?

Short codes offer many distinct advantages over traditional communication methods, revolutionizing how businesses connect with their audience. Their efficiency, reliability, and user-friendly nature make them a preferred choice for high-volume messaging campaigns. Here's a detailed breakdown of their unique benefits:

High throughput:

Short codes support the dispatch of many messages per second, a critical feature for businesses managing large-scale campaigns. Plivo’s SMS API takes this further by providing a throughput of 100 messages per second for short codes with room for scalability.

Improved deliverability:

Messages sent via short codes are prioritized by carriers, reducing the likelihood of being filtered as spam. This ensures critical notifications, such as system outages or payment confirmations, are received promptly.

Memorability and branding:

Vanity short codes (e.g., “PLIVO” or 75486) reinforce brand recognition while simplifying the user experience. Plivo’s API supports vanity short codes, ensuring seamless integration with your branding strategy.

Compliance:

Short codes are inherently TCPA-compliant when used correctly. Plivo’s opt-out handling and real-time redaction tools simplify adherence to regulations, protecting your brand from legal pitfalls.

Compliance and opt-in requirements

Navigating the regulatory landscape is crucial for any business utilizing short codes. Under the Telephone Consumer Protection Act (TCPA), explicit customer consent is required before sending promotional messages. This is typically achieved through keyword opt-ins, such as:

• A customer texting “SUBSCRIBE” to your short code.
• The customer’s agreement to your terms of communication.

Plivo’s compliance features:

• Built-in opt-out management, ensuring recipient requests like “STOP” or “UNSUBSCRIBE” are processed automatically.
• Detailed documentation and support to guide businesses through TCPA and CTIA compliance requirements.

Types of short codes

When choosing a short code, businesses must decide between two options:

Random short codes:

Carriers assign these codes sequences of numbers provided by wireless carriers, offering businesses a cost-effective option for high-volume messaging. These codes are chosen at random, without input from the business, which makes them less personalized compared to vanity short codes. 

However, their functionality remains identical, making them an excellent choice for businesses where branding isn’t the primary focus, but reliable and efficient messaging is. For example, a logistics company sending delivery notifications or a healthcare provider sharing appointment reminders may prioritize the affordability and utility of a random short code over the memorability of a vanity code. 

Random short codes deliver the same performance benefits, such as high throughput and carrier prioritization, without the added expense of customization.

Vanity short codes

Vanity short codes are fully customizable 6-digit numbers that allow businesses to align their messaging strategy with their brand identity. These codes are typically chosen to spell out a word or phrase associated with the business, like “PLIVO” (75486), making them highly memorable for customers. The customization not only aids in recall but also builds trust and credibility by reinforcing the brand every time the code is used.

While vanity short codes are more expensive than random ones, their value lies in their ability to create a cohesive and recognizable brand experience. For instance, a retailer running nationwide loyalty programs or a media company promoting a recurring event might find the investment worthwhile to maintain a strong brand presence in every interaction.

Since the industry-wide discontinuation of shared short codes due to security concerns, dedicated short codes—whether random or vanity—have become the norm. These provide businesses with exclusive use of their short code, ensuring messages are not only delivered but also free from the risks of being flagged or associated with other entities.

How to lease and acquire a 6-digit phone number?

Leasing a short code involves navigating carrier requirements and compliance approvals. The process includes:

• Selecting a random or vanity short code based on your goals and budget.
• Completing carrier documentation, including details on message types and compliance measures.
• Testing and launching your campaigns.

This process can seem complex, but Plivo makes managing short codes effortless by providing end-to-end support, from application submission to campaign setup. With over a decade of experience, Plivo helps businesses go live with their short codes quickly and efficiently.

Text message scams, or smishing, are becoming increasingly sophisticated, making it harder to tell if a message is real or fake. More than 3.5 billion phone users receive spam text messages that trick individuals into sharing sensitive information, such as credit card details, social security numbers, and banking credentials. 

While many think they can spot a scam from a mile away. But, in reality, only less than 35% of the population knows what smishing is. These fraudulent messages can look shockingly legitimate. 

In this post, we’ll show you how to identify a fake text message, and provide tips on how to protect yourself.

What is smishing?

Smishing is a form of phishing conducted via text messages. These fraudulent SMS attempts often appear to come from trusted entities—your bank, government agencies, even friends or family—convincing you to share private information or click on malicious links.

The goal of smishing is to steal your sensitive data or install malicious software on your device. These texts often play on emotions, like urgency or fear, to prompt quick action.

What are some common traits of scam text messages?

1. Unsolicited texts from unknown or spoofed numbers
   A typical characteristic of a scam text is that it comes from an unfamiliar number. While legitimate businesses use shortcodes or toll-free numbers, scammers often spoof these to make the text appear trustworthy. If you receive a text from a random, long-numbered, or suspicious source, take extra caution.
2. Urgent requests or alarming content
   Fake texts often claim urgent issues like unauthorized bank transactions, problems with accounts, or family emergencies that require immediate action. Scammers know that stress and fear can cloud your judgment, so they pressure you into taking quick, unthought-out actions.
3. Strange grammar or formatting
   Look for signs like spelling errors, awkward phrasing, or inconsistent formatting. Real businesses take care in crafting their messages, while scammers might rush or use poor language to disguise their intentions.

What are the common types of text message scams?

Understanding the types of scams is key to recognizing them before it’s too late. Here are a few common examples:

1. Missed delivery notifications
   You might receive a text claiming that a package was undeliverable and prompting you to visit a suspicious website or call a fake customer service number.
2. Prize or sweepstakes notifications
   A scammer might tell you that you’ve won a prize but need to pay a fee or provide personal details to claim it. Be especially wary if you’ve never entered any contests.
3. Bank account closure threats
   Scammers pretending to be from your bank may warn that your account is about to be locked unless you take action immediately. These texts often include fake links or phone numbers to collect your login details.
4. Subscription service payment failures
   If you receive a text claiming a failed payment for a service you use, be cautious. Scammers use this tactic to extract payment information or prompt you to visit malicious websites.

How do scammers use text messages?

Scammers typically rely on tactics that mimic trusted brands or entities to trick victims into responding. These tactics include:

1. Impersonating reputable companies or individuals: Scammers may pose as well-known organizations like your bank, delivery services, or government agencies to gain your trust.
2. Spoofing phone numbers: By making it appear as though a trusted number is sending the message, they increase the likelihood of you believing the scam.
3. Social engineering: Scammers tailor their messages to seem more believable using information gathered from previous data breaches or public sources.
4. Unsolicited messages with suspicious links or requests
   Unsolicited messages containing unexpected links or requests should always be approached with caution. Pay attention to details like URLs that closely mimic legitimate domains but include slight variations, such as additional characters or unfamiliar extensions. 

Avoid clicking on links in these messages. Instead, verify the authenticity by directly visiting the organization's website through a trusted search engine or contacting them via official channels. 

How to identify scam text messages?

What protective measures can you take against text scams?

To avoid falling victim to smishing attacks, follow these protective steps:

1. Avoid responding to suspicious texts
   Don’t engage with any message you suspect to be a scam. Even responding with “STOP” or “REMOVE” may confirm to the scammer that your number is active, leading to more fraudulent attempts.
2. Block spam numbers
   If you receive a suspicious text, block the number immediately. Your phone’s settings or mobile provider’s app will usually allow you to do this.
3. Use Plivo’s SMS API for secure communication
   For businesses, one of the best ways to prevent smishing and safeguard your business communication is by using Plivo’s SMS API fraud shield to ensure safe and secure messaging. Plivo offers robust tools for verifying customer phone numbers, authenticating accounts, and detecting fraudulent activity. 

Plivo’s API helps prevent spoofing and ensures that your SMS communication is secure, reducing the risk of text scams for your business and customers.

How to report and address text message scams?

In the interconnected world of apps, websites, and digital services, ensuring secure user access is more critical than ever. That’s where authentication and authorization come into play. These two terms often appear side-by-side in conversations about cybersecurity and user access, but they’re far from interchangeable.

Think of authentication as verifying your identity at the door, and authorization as the VIP list determining what areas you can access once inside. Both are essential for keeping digital spaces secure, but their roles are distinct—and understanding the difference is key to building safer systems and more seamless user experiences.

In this blog, we’ll break down the fundamentals of authentication and authorization, explore how they work together, and examine why they matter for individuals and organizations alike.

How does authentication verify user identity?

Authentication is the cornerstone of digital security, tasked with verifying that a user or entity is genuinely who they claim to be. Without authentication, systems cannot differentiate between legitimate users and malicious actors attempting unauthorized access.

At its core, authentication involves a user providing credentials—such as a username and password—that are compared against stored data. If the credentials match, the system permits access. However, traditional methods like passwords have vulnerabilities, prompting the adoption of more advanced techniques.

What are the common types of authentication methods?

Authentication mechanisms can be classified into three main categories based on the type of credentials required:

1. Something you know: Includes passwords, PINs, and answers to security questions. These methods rely on the assumption that only the authorized user knows the required information.
2. Something you have: Examples include physical devices like security tokens, mobile phones for OTP delivery, or smart cards. These add an extra layer of security by requiring possession of an item.
3. Something you are: Biometric authentication leverages unique physical attributes like fingerprints, iris scans, or facial recognition, making it one of the most secure forms of identity verification.

Combining these methods through multi-factor authentication (MFA) strengthens security by requiring two or more forms of verification.

Why is multi-factor authentication (MFA) critical?

While traditional authentication methods offer a basic level of security, they can be vulnerable to attacks such as phishing or credential theft. This is where multi-factor authentication (MFA) comes in—by requiring two or more verification methods, MFA significantly reduces the risk of unauthorized access. For instance, a banking application might require both a password (something you know) and an OTP sent to your mobile device (something you have) before granting access.

MFA mitigates common vulnerabilities of single-factor authentication by making it harder for attackers to breach systems, even if one credential is compromised. It is particularly important for high-security environments such as financial institutions or cloud services.

How does authentication operate in cloud environments?

With businesses rapidly shifting to cloud-based platforms, authentication must evolve to meet the challenges of remote access and global connectivity. Cloud computing, with its shared infrastructure and global accessibility, demands robust authentication mechanisms. Traditional username-password combinations are often insufficient, so advanced approaches like token-based authentication and Single Sign-On (SSO) are widely used. These methods simplify access for users while maintaining strict security standards.

For example, SSO enables users to authenticate once and access multiple applications seamlessly. Coupled with standards like OAuth 2.0 and OpenID Connect, SSO ensures both security and convenience, making it an integral part of modern authentication in cloud environments.

How do authentication and authorization work together?

Authentication and authorization are integral processes that work in sequence to protect systems and data. Authentication identifies who the user is, while authorization determines their permissions within the system. Together, they ensure that only verified users gain access to the resources they are allowed to use, forming a robust framework for digital security.

Why must authentication always precede authorization?

Authentication and authorization are sequential processes that work in tandem to secure systems and data. Authentication verifies a user’s identity, forming the foundation for authorization to define what the user can do within the system. Without authentication, a system cannot determine whether a user is legitimate, making it impossible to assign permissions accurately.

For example, consider an enterprise resource management system. Authentication ensures a user, such as a department manager, is genuinely who they claim to be. Once authenticated, authorization evaluates their role and grants access to department-specific data while restricting other sensitive areas, such as payroll records for other departments.

What protocols effectively integrate authentication and authorization?

1. OpenID Connect (OIDC)
   OIDC, built on OAuth 2.0, focuses on user authentication by verifying identity and providing ID tokens to applications. It is particularly useful in Single Sign-On (SSO) environments, enabling users to authenticate once and access multiple applications seamlessly.
2. OAuth 2.0
   OAuth 2.0 primarily handles authorization. It issues access tokens that grant limited permissions to third-party applications. For instance, a user can authorize a travel app to access their calendar to book flights without sharing their login credentials.

Together, OIDC and OAuth 2.0 provide a cohesive framework for managing authentication and authorization, ensuring secure and streamlined access control.

How do authentication and authorization complement each other in IAM systems?

Identity and Access Management (IAM) systems rely on the synergy between authentication and authorization to provide comprehensive security. While authentication confirms a user’s identity, authorization enforces granular access controls based on predefined policies.

For example:

• A marketing analyst authenticates into a shared cloud platform.
• Authorization allows access to customer analytics dashboards but restricts access to sensitive financial data meant for the finance team.

This integration not only enhances security but also improves the user experience by ensuring users can seamlessly access the resources they need without encountering unnecessary barriers.

What are the strengths and weaknesses of traditional authentication methods?

Traditional authentication methods often rely on verifying something a user knows, such as a password or PIN. While straightforward and familiar, these methods have inherent weaknesses:

1. Password-based authentication:
   
   • Strengths: Universally understood and simple to implement.
   • Weaknesses: Susceptible to phishing, brute-force attacks, and credential stuffing. Users often reuse or create weak passwords, making them a common attack vector.
2. Knowledge-based authentication (KBA):
   
   • Strengths: Uses answers to security questions, adding an extra layer of protection.
   • Weaknesses: Answers can often be guessed or researched, especially when questions rely on personal information.

These methods, while widely used, require additional safeguards to address their vulnerabilities.

How do biometric and possession-based methods enhance authentication?

Authentication methods based on something a user has or is, provide a higher level of security:

1. Possession-based authentication:
   Examples include physical devices like smart cards, security tokens, or mobile phones used to receive one-time passwords (OTPs).
   
   • Strengths: Tied directly to the user's possession, making them harder to replicate.
   • Weaknesses: Devices can be lost or stolen, potentially compromising security.
2. Biometric authentication:
   Employs unique physical traits like fingerprints, retina scans, or voice recognition.
   
   • Strengths: Difficult to forge and highly reliable when implemented correctly.
   • Weaknesses: Biometric data, if compromised, cannot be replaced, raising significant privacy concerns.

These methods often form the foundation of multi-factor authentication (MFA) systems, combining possession or biometric factors with traditional credentials to mitigate risks.

What are adaptive and passwordless authentication techniques?

Advanced authentication techniques are emerging to address the evolving threat landscape and user demands for convenience:

1. Adaptive authentication:
   Uses machine learning and context-aware policies to evaluate risk factors, such as location, device, or login time.
   
   • Example: A system might prompt for additional verification if a user logs in from an unusual location.
   • Strengths: Dynamically adjusts security measures based on risk, improving both security and usability.
2. Passwordless authentication:
   Eliminates the reliance on traditional passwords, using methods like biometrics, hardware tokens, or magic links sent to a user’s email.
   
   • Strengths: Reduces phishing risks and enhances user convenience.
   • Weaknesses: Requires advanced infrastructure and user education for widespread adoption.

These approaches represent the future of secure and user-friendly authentication systems.

What are the key differences and similarities between authentication and authorization?

Authentication and authorization serve distinct purposes in access control systems:

• Authentication: Focuses on verifying identity. It answers the question, "Who are you?" and allows only legitimate users to log in. Examples include passwords, biometric scans, or OTPs.
• Authorization: Determines what a user is allowed to do after they’ve been authenticated. It answers, "What are you allowed to access?" For instance, an authenticated user might be able to view files but not edit them.

The main distinction lies in their roles: authentication validates identity, while authorization defines permissions.

How do tokens facilitate both processes?

In modern access control systems, tokens play a critical role in separating authentication and authorization:

1. ID Tokens:
   
   • Issued during authentication to confirm a user’s identity.
   • Typically contains user details such as name, email, and login time.
   • Example: OpenID Connect generates ID tokens after a user logs in.
2. Access Tokens:
   
   • Issued during authorization to define the permissions granted to the user or application.
   • Allow a user to interact with specific resources (e.g., files, APIs) without revealing sensitive credentials.
   • Example: OAuth 2.0 uses access tokens to permit third-party apps to access user data within predefined limits.

By segregating authentication (ID tokens) and authorization (access tokens), systems maintain both security and clarity in managing access.

How do authentication and authorization complement each other?

Authentication and authorization are complementary processes, working together to provide robust access control:

1. Authentication establishes trust: Ensures that only legitimate users enter the system.
2. Authorization enforces boundaries: Restricts user actions based on predefined policies.

For example, in a corporate email system:

• Authentication verifies an employee’s identity via a company-issued login.
• Authorization determines whether the employee can access confidential documents or edit shared files.

Together, these processes create a multi-layered security approach, minimizing risks like unauthorized access and data breaches.

Why are both authentication and authorization critical for complete security?

Neither authentication nor authorization can independently secure a system. Relying solely on authentication might let verified users access sensitive areas they’re not permitted to view, while exclusive reliance on authorization without authentication would grant access without ensuring the user is legitimate.

For example:

• A cloud storage system might authenticate a user with valid credentials but use authorization to restrict access to sensitive financial reports, ensuring that only authorized roles, such as CFOs, can view them.

This synergy is particularly vital in regulatory compliance environments like HIPAA, where access to sensitive information is strictly governed.

Overview of SMS 2FA

SMS 2FA (two-factor authentication) adds a critical layer of security to online accounts. When users log into a website, software, or application, they receive a one-time numeric code via text message. This code acts as a second step in the authentication process, ensuring only the individual with access to the linked phone number can proceed.

For businesses in retail, healthcare, and fintech, SMS 2FA is a popular choice to safeguard sensitive customer data and prevent unauthorized access. By requiring something users know (a password) and something they have (a mobile phone), it significantly reduces the risk of data breaches.

While SMS 2FA is simple to implement and user-friendly, its security depends on how well it addresses threats like phishing and SIM swapping. As decision-makers, you need to weigh its ease of use against the level of protection it offers your business and customers.

So, why did businesses initially gravitate towards SMS 2FA? Let's examine the factors that made it a preferred choice in the early days.

The early appeal of SMS 2FA

SMS 2FA quickly gained traction as a security solution because of its simplicity and compatibility with existing devices. Here's why it became a preferred choice for businesses initially:

• No extra hardware required: Users only need their smartphones, eliminating the cost and hassle of additional authentication devices.
• Wide accessibility: With the ubiquity of mobile phones, SMS 2FA reaches a broad audience across different demographics.
• Ease of implementation: Businesses can integrate SMS 2FA seamlessly into existing login processes using APIs, reducing setup complexity.

Let's now walk through the steps involved in a typical SMS authentication process.

How does SMS authentication work?

SMS authentication offers a simple way to enhance security while keeping the user experience intuitive. Here’s how it works:

1. User logs in:

A customer visits your website and enters their username and password to log in. They trust your platform with their personal information and expect a smooth, secure experience.

2. One-time password (OTP) sent:

Immediately, your system triggers an SMS with a unique one-time password (OTP) sent to the customer’s registered phone number. This step adds an extra layer of security beyond just their password.

3. User inputs OTP:

The customer receives the OTP on their mobile device and enters it into the login screen. This ensures the person trying to access the account is the legitimate user, as only they would have access to the phone where the OTP was sent.

4. Access granted:

If the OTP matches, your system verifies the user’s identity and grants them access to their account. With SMS authentication in place, your business reduces the risk of unauthorized access, enhancing both security and customer trust.

This approach to SMS authentication strengthens security, reassures customers about their data, and keeps the login process simple and user-friendly.

SMS authentication became a preferred security method for businesses due to its simplicity and effectiveness. Here’s why it stands out:

Enhanced security

Adds an extra layer of protection compared to passwords alone, reducing the risk of unauthorized access.

Example: A financial institution uses SMS authentication to protect user accounts. When a customer logs in, they are sent an OTP to their mobile number. This step ensures that even if an attacker gains access to the username and password, they would still need the phone to complete the login. This added protection helps the bank mitigate fraud and safeguard sensitive customer information.

Convenient for users

No need for extra hardware or software, making it accessible to all users, even those with basic mobile phones.

Example: A small e-commerce business implements SMS 2FA for its customers. By sending OTPs directly to users’ mobile phones, the business ensures security without forcing customers to download apps or use advanced authentication methods. The simplicity of SMS ensures customers don’t feel overwhelmed, leading to higher user adoption and satisfaction.

Offline functionality

SMS works without an internet connection, making it a reliable option for users in low-connectivity areas.

Example: A non-profit organization serving rural areas uses SMS authentication for its donation platform. Many of its supporters don’t have reliable internet access, so SMS-based 2FA ensures they can securely log in to donate without worrying about data connectivity, increasing overall participation.

Widespread compatibility

SMS is compatible with almost all mobile devices, ensuring accessibility for a diverse user base.

Example: A healthcare provider implements SMS-based 2FA for patient portal access. Since nearly all patients have mobile phones, they can easily receive OTPs regardless of their device type, which makes the authentication process seamless and user-friendly across their varied demographic.

Ease of deployment

Simple to implement, requiring minimal changes to existing systems, which saves time and resources.

Example: A SaaS company offering cloud storage services introduces SMS authentication to its login process. With minimal updates to their infrastructure and integration via APIs, the company quickly deploys SMS 2FA, improving security without a significant investment in new technology or disrupting the existing user experience.

User familiarity

Most users are already comfortable receiving and entering OTPs, reducing friction in the login process.

Example: A major online retailer uses SMS 2FA as part of its login process. Customers are already familiar with the concept of receiving OTPs via SMS, so the retailer enjoys quick adoption of the new security feature. This reduces any friction in the user experience, leading to fewer drop-offs during the authentication process.

Cost-effective

Eliminates the need for costly authentication devices, making it budget-friendly for businesses of all sizes.

Example: A small-to-medium-sized business (SMB) offering online services opts for SMS 2FA instead of purchasing specialized hardware tokens for each employee. The cost savings from using SMS-based authentication are reinvested into improving other areas of the business, allowing the company to strengthen security without compromising on budget.

Quick adoption

Works seamlessly across industries, addressing diverse security needs.

Example: A hotel chain in the hospitality industry adopts SMS authentication to streamline guest logins for its loyalty program. Whether the guest is a frequent traveler or a first-time visitor, the simple SMS authentication process is intuitive and quick, leading to widespread adoption and enhanced security for guest data.

SMS authentication strikes the right balance between user convenience and robust security, ensuring smooth operations while protecting sensitive data for decision-makers.

Best practices for sending promotional text messages

To maximize the effectiveness of your promotional text messages, it's crucial to follow a few key best practices.

Timing and frequency

Send messages during optimal times—typically within business hours or late afternoons—when recipients are more likely to engage. Avoid sending messages too early in the morning or too late at night, as this can annoy customers.

Frequency is equally important. Sending messages too frequently can overwhelm your audience, while too few messages may lead to missed opportunities. A good guideline is to send no more than 1-2 promotional messages per week.

Obtaining consent: why opt-in is crucial

Before sending any promotional messages, always obtain explicit consent from your customers to ensure compliance with regulations like the Telephone Consumer Protection Act (TCPA) and GDPR. Opt-in permissions also help build trust with your audience. Use clear opt-in messages, such as "Sign up for exclusive offers via SMS," and always provide an easy way to opt-out, like "Reply STOP to unsubscribe."

Crafting a clear call-to-action (CTA)

Each promotional message should feature a direct, clear CTA. Whether it’s “Shop now,” “Claim your discount,” or “Visit our store,” ensure that the CTA is straightforward and easy for the recipient to act upon.

Tracking the effectiveness of SMS campaigns

Tracking key metrics such as open rates, click-through rates (CTR), and conversion rates is essential to evaluate the success of your SMS campaigns. By monitoring these metrics, you can identify what’s working, make necessary adjustments, and optimize your future campaigns for better results.

Legal considerations

When using SMS for promotional campaigns, businesses must ensure they are compliant with various laws and regulations designed to protect consumers from unwanted marketing and data misuse. These regulations govern the use of SMS as a marketing tool and are in place to prevent abuse, such as spamming customers with unsolicited messages. Non-compliance can result in heavy fines, legal repercussions, and damage to your brand’s reputation.

Multi-Factor Authentication (MFA) is an essential safeguard for protecting sensitive information. However, as crucial as it is for security, the MFA recovery process can sometimes be a double-edged sword. If users lose access to their authentication method, they risk being locked out of their accounts. Therefore, a robust MFA recovery process should be a critical part of any authentication strategy.

Let’s walk through best practices for MFA account recovery to ensure your users can easily and securely regain access to their accounts.

Authentication requirements for account recovery

While traditional MFA methods provide excellent security, the MFA recovery process requires a slightly different approach. Recovery methods must be easily accessible, and memorable, and allow for a slower authentication process. Recovering an account isn't something most users would be required to do regularly.

The key requirements for a recovery system are:

1. Long-term memorability or access: Users need to easily retrieve their recovery method, even if they don’t use it regularly.
2. A slower authentication process is acceptable: Since account recovery is infrequent, a slight delay in authentication is fine as long as security is not compromised.
3. Widely usable: The recovery method must be accessible and practical for most users across different devices and locations.

The right balance is essential. Your recovery process should be secure enough to prevent unauthorized access but user-friendly enough to prevent frustration. 

Plivo’s Verify API, which supports multiple channels like SMS and in-app push notifications, can be an excellent tool for ensuring users have quick, secure access to their recovery methods.

What are the options for account recovery?

Gone are the days of relying on security questions for account recovery. The National Institute of Standards and Technology (NIST) has since recommended shifting away from these outdated methods due to their vulnerability. Today, the most reliable account recovery options involve using possession-based methods or account activity details.

1. Possession methods

Possession-based recovery methods are more secure than knowledge-based methods like security questions. Examples include:

• Backup codes: These are typically one-time-use codes that can be generated during the initial MFA setup. Users should store these codes securely in case of device loss or other issues. While they may seem simple, they offer a solid layer of security.
• Passkeys: A passwordless option that syncs private keys across devices, making it easier for users to recover their accounts without needing to remember complex passwords. Although passkeys are still being adopted, they offer a promising solution for both MFA and recovery.

Implementing these methods provides a secure fallback when users lose access to their primary authentication methods. Plivo’s Verify API can easily integrate into your system to deliver SMS-based recovery codes, offering both security and simplicity for users who need to regain access.

2. Account activity details

Another way to strengthen your recovery process is by leveraging account activity details. For example, asking users to confirm recent transactions or other identifiable actions can serve as a powerful recovery tool. These methods provide additional layers of security, helping to confirm a user's identity when primary credentials are unavailable.

How can social proof enhance account recovery processes?

Digital services and online platforms such as social networks or apps use trusted contacts or social proof to enhance their recovery processes. This could be a friend or family member who can verify the user’s identity. For example, platforms like Apple and Facebook use recovery contacts, allowing users to set up people who can help them regain access if needed.

However, this method works best for social networks with a large, established user base. If your service doesn’t have this feature built-in, focusing on other recovery options—such as backup codes and passkeys—can still provide strong security and ease of use.

How to strengthen your account recovery process?

To improve your account recovery process, consider the following recommendations:

1. Register additional authentication methods: Ensure that users register multiple recovery methods during account setup. This gives them options to access their account if they lose access to one method.
2. Design recovery processes based on data sensitivity: The higher the value of the data you're protecting, the more robust your recovery process should be. For sensitive services like financial applications, additional security layers are necessary.
3. Require successful MFA setup before new methods: Before enabling new MFA methods, ensure users have successfully completed the MFA setup process to avoid issues during recovery.
4. Prompt users about available recovery options: Regularly remind users of the backup methods available to them, particularly when logging in from new devices or after a password change.

Enhancing recovery process security

When enhancing your recovery process, keep these security measures in mind:

1. Implement waiting periods: For sensitive recoveries, a waiting period can act as a deterrent for unauthorized access attempts. This gives you time to review and confirm that the recovery request is legitimate.
2. Maintain MFA during recovery: Don’t deactivate MFA when users are trying to recover their accounts. This ensures that multiple authentication steps are still in place, preventing unauthorized access.

The MFA recovery process should always remain as secure as possible, even if it’s a bit slower than regular authentication. By adding layers of security, such as SMS or app-based MFA, you can ensure that both you and your users stay protected.

Voice commerce is a $421.7 billion opportunity.

Yes, more than 27% of U.S. consumers made online payments with voice assistants instead of manually browsing multiple screens and navigating the checkout process. Devices like Amazon Echo, Google Home, and Samsung SmartThings now act as virtual shopping assistants.

With the number of voice search users anticipated to reach 157.1 million by 2026, voice commerce opens up a faster purchasing channel. For businesses, this means a higher conversion rate, stronger sales, and streamlined customer support.

In this blog post, we’ll explore voice commerce, how it works, and its benefits for your business.

What is voice commerce?

Voice commerce, or v-commerce, is a technology-driven shopping experience that allows customers to search for, purchase, and manage orders using voice commands. It reduces the reliance on screens and keyboards during the buying process.

The technology relies on two components: smart speakers that convert speech into digital commands and AI assistants that interpret these commands and take action. Customers can shop hands-free while cooking, driving, or multitasking.

How does voice commerce work?

The process starts when your customer speaks a command into voice-enabled devices. While it seems simple on the surface (the customer speaks and the device responds), the technology performs several steps to complete each task. These steps include:

• Converting speech to actionable data: Your customer's spoken command gets captured and converted to text through automatic speech recognition (ASR) algorithms. For example, when they say "buy new headphones," the system captures each word.
• Understanding customer intent: The system analyzes this text to understand what your customer wants. It breaks down the command to identify the action (buying) and the product (headphones). This involves natural language processing (NLP) to interpret the meaning behind the words.
• Finding the right products: Once the system understands the intent, it searches your product database or online store for relevant items. It pulls up matching products, prices, and availability.
• Creating the right response: Then, the system creates a response based on its findings. If multiple headphone options exist, it might ask for more specifics about the price range or features your customer wants.
• Completing transaction: The customer can then confirm their choice, and the system completes the transaction — adding headphones to the cart, processing payment, or scheduling the delivery.

When you implement voice commerce for your business, pay attention to the following:

• Speech recognition must handle different accents and background noise.
• Your product database needs clear categorization for accurate matching.
• Response systems should sound natural while providing accurate information.

Plivo’s AI voice agent makes integrating voice commerce simple. The platform combines three models: speech-to-text (STT) to convert customer voice to text, large language models (LLM) to understand customer intent, and text-to-speech (TTS) for natural responses.

Here's how an interaction with Plivo’s AI voice agent flows:

Customer: "I want to buy a new dress."

AI voice agent: "What style or color are you looking for?"

Customer: "A red cocktail dress."

AI voice agent: "We have red cocktail dresses in stock. What size do you need?"

Customer: "Medium."

AI voice agent: "Found a medium red cocktail dress. Ready to check out?"

Customer: "Yes."

AI voice agent: "Order confirmed. Delivery in three business days."

Each question narrows down options until the customer finds exactly what they want. The system handles real-time conversations with minimal latency and can process and respond to mid-speech interruptions.

Plus, you can train it on your product database and business rules to deliver relevant, contextual responses.

You also control the tech stack behind these interactions. Integrate Plivo with your preferred tools for speech recognition (like Deepgram), language processing (OpenAI), and voice generation (ElevenLabs).

Benefits of voice commerce for business

Let’s now look at what voice commerce means for your business.

Increased key sales metrics

Voice assistance commerce will claim nearly 30% of all e-commerce revenue by 2030. It directly impacts the sales metrics and drives growth through:

• Increased conversion rates: Instead of manually searching for items, customers have to speak to get instant tailored recommendations. This makes shopping more intuitive and reduces drop-offs, leading to a higher conversion rate.
• Reduced cart abandonment rates: Many customers abandon carts due to lengthy or complex checkout processes. Commands like “Buy this now” or “Complete my order” will reduce friction and promote seamless shopping experiences.
• Improved customer lifetime value (CLV): Simplified reordering of previous purchases increases sales frequency and long-term customer retention. Customers can simply say, “Reorder my protein powder” or “Buy the same shampoo as last time.”
  
  • Impact:
    
    • Reduces effort, making repurchasing quick and effortless
    • Customers stick with the brand due to convenience
    • More frequent purchases → Higher CLV

For example, Starbucks integrated voice ordering through Amazon's Alexa for customers to place orders via voice commands. This led to a 16% higher monthly revenue per user from customers who used the feature.

Reduced support cost

Voice commerce reduces support costs as it handles routine customer inquiries with ease. Your support team can focus on complex issues while the voice system manages common questions about order tracking, store hours, and product information.

The system operates 24/7, so customers get immediate answers without waiting for support staff. This self-service approach cuts call volumes and support queue times. Plus, voice assistants can manage multiple customer conversations simultaneously, eliminating additional staffing costs.

Improved customer experience

82% of customers report that personalization drives brand choice. With tailored recommendations and natural conversations, voice agents let customers connect with your brand on their terms.

For example, Domino's virtual voice ordering assistant, Dom, handles customized orders, suggests additions, and finds the best deals.

Beyond convenience, voice commerce helps collect direct customer feedback to improve your service. Customers can quickly share their thoughts through simple voice commands, helping you understand and address customer needs faster.

Challenges of voice commerce

Voice commerce brings three core challenges you need to consider.

Technological complexity

Voice commerce relies on expertise in NLP and voice recognition technology to get started. The system must accurately capture and convert voice commands to text, even with different accents and noisy backgrounds. Misinterpretations of customer queries can affect the entire brand's reputation and reduce customer satisfaction.

Invest in advanced NLP and machine learning algorithms to improve performance. Partnering with a voice-first vendor like Plivo gets the task done through high-quality, low-latency audio and context-aware interactions without a hitch.

Security concerns

Voice commerce shoppers often worry about their data being recorded, stored, and potentially shared with third parties since AI handles sensitive customer data.

This system requires extra security layers for data protection and purchase verification. Businesses must address potential vulnerabilities to prevent fraud or unauthorized access through sophisticated encryption techniques.

Integration challenges

Your voice platform must connect with your e-commerce infrastructure, inventory management, payment processing, and customer data systems. The system should also sync with your product database for accurate pricing, availability, and descriptions.

While platforms like PayPal support voice transactions, many payment systems and banks don't offer voice commerce capabilities yet.  This can slow implementation and limit your growth potential until more providers adopt voice technology.

Measures to make voice commerce the next big thing

Voice commerce relies on advanced technology, but making it right doesn’t have to be complicated. Let’s look at measures to ensure its success and drive customer engagement.

Boost discoverability with voice search SEO

Voice search behavior differs from text — your customers speak in full sentences of 6-10 words. They ask, "Show me high-performance running shoes under $100" instead of "running shoes." So, connect your catalog with search engines and optimize product descriptions for these longer, conversational searches.

With 18% of global consumers using voice shopping weekly, discoverability improves when you optimize for natural speech patterns.

Streamline purchases with voice-activated shopping

Set up quick voice checkout flows and minimize steps between product discovery and purchase.

Nike launched Adapt BB shoes through Google Assistant. Fans bought the entire stock in six minutes using voice commands during an NBA game halftime. The launch proved voice shopping can drive quick sales when you make purchasing effortless.

Deliver hassle-free support with voice AI

Train your voice AI on common customer issues. Build responses for tracking, returns, product specs, and shipping questions. Update the system with new products and policies. For example, 1-800-Flowers runs voice self-service for customers to track orders, change delivery details, and check FAQs. This support channel works 24/7, letting customers get help when they need it.

Track voice commerce performance

Set clear metrics for your voice channel and use insights to refine your strategy. Track voice-activated sales, search volume, and support requests. Monitor how voice affects customer behavior. Do they order more often? Place bigger orders? Buy different products?

Analyze patterns and optimize voice interactions to improve customer engagement and maximize ROI. Voice support cuts operational expenses, and self-service options reduce agent workload. This automated ordering speeds up sales processing.

Turn customer insights into smarter strategies

Update your voice features based on user needs. Fix common pain points, add requested features, and remove unused options.

Estée Lauder's voice-enabled makeup assistant (VMA) collects user input during key moments of the experience. Customers share thoughts through voice commands or the feedback menu. Their app updates reflect direct user feedback.

Voice commerce then, now, and beyond

From basic speech recognition to sophisticated shopping systems, voice commerce has evolved so much. Here’s a timeline of the evolution:

• IBM's 1961 "Shoebox" could understand just 16 spoken words.
• In 1971, Carnegie Mellon's "Harpy" system processed 1,000 words through DARPA funding.
• The real breakthrough came in the 1980s when Dragon Systems brought speech recognition to personal computers.
• The 2010s marked the shift to mainstream voice commerce adoption:
  
  • Apple's Siri (2011) introduced voice assistance to millions of iPhone users.
  • Amazon's Alexa voice assistant (2014) transformed voice shopping by connecting speech recognition with e-commerce.
  • Google Assistant (2016) joined the voice commerce market, driving competition and innovation.

Today, voice commerce is no longer used just for single-store transactions. Businesses can now integrate with multiple voice platforms — Alexa supports transactions for Walmart, Best Buy, 1-800-FLOWERS, and Starbucks. Customers only need to link their retail accounts to start voice shopping.

REI Co-op, Redbox, and eBags also use the platform to distribute deals and track orders.

Apple Store handles peer-to-peer payments through Siri. Walmart's mobile app tests hands-free shopping, order scheduling, and voice-based customer support.

The market shows strong growth potential. Research projects voice commerce to grow at a CAGR of 24.34% annually from 2024 to 2030. That means v-commerce is slowly becoming a necessity to stay competitive for businesses.

Natural language processing (NLP) works behind the scenes in places you might not even notice — filtering spam emails, customer service chatbots, and even accurate Netflix recommendations. It’s woven across industries and is rapidly evolving, with the market projected to hit 156.76 billion by 2030.

It's natural to wonder whether NLP is too complex or worth integrating into your systems. This guide offers five digestible NLP steps so you can understand how the technology works and whether it’s a good fit for your business.

What is NLP?

Simply put, NLP lets a machine understand, interpret, and respond to human language, written or spoken. It's the reason voice assistants listen to your commands, chatbots answer your queries, and search engines predict what you’re looking for even before you finish typing.

The NLP process is powered by two key components.

Natural language understanding (NLU) helps machines decode what humans mean, even if the content isn't totally clear. For example, customer support chatbots use NLU to recognize when a user is frustrated (based on words like “poor service” or “I need help now”) and escalate the issue appropriately.

Once the machine understands what the user is saying, natural language generation (NLG) generates a response in a way that sounds natural. Instead of just responding with pre-set phrases, the system personalizes the response based on the user’s request, offering logical next steps, similar to how a human agent would.

Here’s a quick rundown of the stages of NLP:

• Splits sentences into smaller chunks (tokenization in NLP) for easier processing.
• Identifies keywords, grammar, and structure to understand context.
• Detects names, dates, locations, and brands (e.g., virtual assistants retrieving order details).
• Determines if a message is a question, request, or complaint for accurate chatbot/voice assistant responses.
• Assesses tone and emotions to gauge customer satisfaction in chats.

To better understand NLP techniques, let’s go through the most common everyday NLP applications.

Most common everyday NLP applications

Along with autocorrecting and filtering spam emails, NLP is most commonly used in the following use cases:

• Chatbots and virtual assistants: NLP enables AI chatbots in customer service to understand and respond to human language, improving customer support and user engagement. These virtual assistants handle tasks like answering FAQs, scheduling appointments, and providing 24/7 customer service, mimicking human interactions to improve efficiency.
• Language translation: Tools like Google Translate use NLP to provide real-time multilingual support. You use this to communicate with global customers and break language barriers in customer service.
• Sentiment analysis: How does a machine know when a caller is frustrated, angry, or simply uninterested in your product? Sentiment analysis scans customer reviews, support tickets, or even social media mentions to determine if the feedback is positive, negative, or neutral. You can use it to gauge customer opinions.
• Speech recognition and voice AI: Speech recognition converts spoken words into text which helps businesses with real-time transcription, AI-driven interactive voice response (IVR) responses, and improved call routing. An advanced ASR (automatic speech recognition) tool like Plivo also masks inappropriate content in transcriptions and improves speech recognition accuracy by providing a list of hint words expected from the caller.

Now that we know about the most basic everyday NLP applications, let’s understand the five NLP steps in detail. 

5 steps in natural language processing

Let’s go through the five steps in NLP with examples.

Step #1: Lexical analysis

Text preprocessing in NLP precedes lexical analysis as it undergoes cleaning, tokenizing, and structuring raw data to make it readable for NLP models.

A study emphasizes that understanding grammatical structures and keywords is vital for chatbots to provide coherent and relevant responses in real-world situations. Lexical analysis helps NLP do so, making it one of the most important natural language processing steps.

It converts a sequence of characters into a sequence of tokens. This tokenization in NLP deciphers and segments languages into units (lexemes), such as sentences, phrases, and words.

Some words can stand alone, like “cat” or “jump”. These are free morphemes because they don’t need any extra help to be complete words. However, then there are bound morphemes, which have to latch onto something else to make sense. For instance,  “replaying”:

• “re-” (a prefix meaning “again”)
• “play” (the root word that holds the meaning)
• “-ing” (a suffix showing it's happening right now)

Neither of these words can exist alone, they always need a root word to stick to.

Machine learning in AI plays an important role in lexical analysis by helping NLP systems continuously improve their ability to identify and segment words accurately. When NLP analyzes text, it goes through a process to understand these layers, which helps understand word meanings, grammatical structures, and even how words change depending on context.

Lexical analysis teaches AI to deconstruct language the way the human brain does, but faster.

Step #2: Syntactic analysis

Syntax is the foundation of language, it’s how words and phrases come together to form meaningful sentences. Syntactic analysis (or parsing) lets NLP systems understand sentence structure and relationships between words rather than analyzing them in isolation.

This ensures that AI-powered chatbots, smart IVR systems, and voice assistants interpret user queries correctly.

When NLP performs syntactic analysis, it:

• Identifies sentence structure: Breaks a sentence into subject, predicate, objects, clauses, etc.
• Determines relationships between words: Determines which words depend on or modify others.
• Checks for grammatical correctness: Ensures the sentence follows valid language rules.

Syntactic analysis is important for chatbots and virtual assistants to improve customer experience with smart IVR. When a customer says, “I need help to reset my password”, the system uses syntactic analysis to recognize:

• “I” as the subject
• “need help” as the action
• “resetting my password” as the specific request

This structured understanding helps the AI respond appropriately, directing users to the right solution without confusion or misinterpretation.

Step #3: Semantic analysis

Semantic analysis in NLP deciphers meaning based on context, intent, and sentiment. The same word or phrase can imply different things depending on how it's used, and semantic analysis ensures AI comprehends these nuances accurately.

For instance, if a caller says, "I need to cancel my order because I wasn’t happy with the last one," a basic AI might fixate on the keyword "cancel" and proceed with the request.

But a Plivo-powered voice agent with semantic analysis understands the full context. It detects dissatisfaction from "wasn’t happy with the last one" and responds empathetically:

• “I’m really sorry about your previous experience. Let’s make this right.”
• Apart from processing the query, it might offer a resolution: “How about a 20% discount on your current order as an apology?”

Semantic analysis helps voice agents understand natural conversations instead of just keywords. This context-aware approach makes customer interactions more human, but you can also use these voice transcriptions for customer analytics to make informed decisions.

Step #4: Disclosure integration

Discourse integration helps NLP models grasp the broader meaning of conversations by considering previous sentences for context. This ensures more accurate interpretations and reduces confusion in AI-driven interactions.

For example, in a customer support chat:

Caller: "I lost my credit card yesterday."

Bot: “I’m sorry to hear that. Would you like to report it as lost or request a replacement?"

Caller: “Cancel it.”

Without discourse integration, the AI might struggle to understand whether the user wants to cancel the report or the card itself. By analyzing the conversation history, it correctly determines that "cancel it" refers to the lost card and proceeds accordingly.

This is important for businesses to automate customer interactions, and ensure smarter, context-aware responses in finance, healthcare, and beyond.

Step #5: Pragmatic analysis

Pragmatic analysis interprets meaning based on context, tone, and real-world knowledge rather than just literal word definitions so that the conversations feel natural and relevant. For instance, when a user asks, "What's the price of your premium subscription plan?"

The bot responds with, "Sure, our premium starts at $50 per month.”

Now, if the user simply responds, "That's a little steep," the bot automatically suggests, "Would you like to explore our standard plan starting at $30?"

While the user doesn't explicitly mention they want to explore a lower-priced option, pragmatic analysis recognizes the implied concern and suggests an alternative.

Businesses benefit from this by providing better customer engagement, fewer misunderstandings, and more effective automation.

While the steps in NLP help make customer experience better, it’s not all pros. 

Challenges and future advancements in NLP

One of the biggest NLP challenges is the bias in AI models.

Since AI learns from human data, it can reflect societal biases, leading to unfair or misleading outputs. MIT researchers developed a technique that reduces bias in AI models while preserving or even improving their accuracy for fairer and more reliable AI decision-making.

Another challenge is understanding regional dialects and slang. Many NLP models struggle with informal speech, code-switching, and cultural nuances, making accurate interpretation difficult in multilingual or diverse environments.

Ethical concerns, such as misinformation, privacy risks, and deepfakes (AI-generated content that falsely mimics real people) add to the complexity.

Looking ahead, context-aware AI conversations will improve chatbot and virtual assistant interactions, making them more natural and relevant. Real-time speech translation is also advancing, aiming for easy, culturally aware translations without robotic phrasing. As NLP evolves, voice integration in conversational AI will focus on making AI communication more inclusive, ethical, and human-like.
