Learn about what voicebots are, the difference between voicebots and traditional IVRs, and the benefits of implementing AI voicebots for contact centres and customer support teams.


We’ve all heard phrases like “Alexa, play Spotify!” or “Siri, what’s the weather today?” AI voicebots like these are becoming increasingly popular. While voice technology has been around for years, its adoption is skyrocketing, driven by their simplicity and ease of use. In fact, the number of digital voice assistants in the world increased from 3.25 billion in 2019 to a staggering 8.4 billion in 2024 according to statista, illustrating the growing reliance on voice technology. As contact centres experience an increasing volume of incoming calls, they are recognising the need to adapt to this new communication style.  

But what exactly is a voicebot, and why have they become so popular? What sets traditional IVRs apart from AI voicebots? 

Let’s dive in to explore how voicebots work, what an AI voicebot is, and how customer service teams can use them to improve the customer experience.

What is a voicebot?

A voicebot (also known as a voice assistant or voice agent) is an AI-powered software application designed to engage with users through spoken language, enabling businesses to automate voice interactions in a way that feels natural and conversational. They serve as virtual voice assistants that convert spoken words into text, understand the user's intent, and generate spoken responses. Powered by conversational AI, voicebots use advanced technologies like Natural Language Processing (NLP) to interpret a caller's intent based on what they say. 

Voice bots are used across various platforms, including mobile apps, smart speakers, customer service lines, and enterprise solutions, to provide a seamless, interactive experience for users. Some popular voicebots include Amazon’s Alexa, Apple’s Siri and Google Assistant.  

Unlike traditional bots that operate via text-based chat, AI voicebots are specifically built to handle voice commands, making them a powerful addition to contact centres and customer support channels that aim to reduce response times, improve accessibility and enhance customer experience (CX). By facilitating seamless, intuitive conversations, voicebots help businesses create more engaging interactions and foster stronger relationships with their customers. 

Voicebot capabilities and key features

Voicebots use artificial intelligence, like conversational AI, and speech recognition technology to interpret and respond to voice commands. This real-time, conversational interaction allows for a smoother, more natural customer experience, making voice bots an increasingly popular solution for customer service, healthcare, retail, and beyond. They’re equipped with capabilities such as: 

  • Automatic Speech Recognition (ASR) 
    ASR is the foundation of any voice bot, enabling it to convert spoken words into text. By capturing the user’s speech and transcribing it accurately, ASR allows the voice bot to process and interpret language quickly. The quality of ASR determines how well a voice bot can handle various accents, dialects, and speech variations—a critical feature for catering to a diverse audience. 
  • Natural Language Processing (NLP) 
    NLP technology is what enables voice bots to go beyond merely recognising words and instead understand the intent behind them. NLP breaks down the structure of sentences, identifies keywords, and uses machine learning to interpret the user’s needs. This understanding is crucial for ensuring that responses are relevant and conversational, creating a seamless dialogue flow. Voice bots with advanced NLP can manage multi-turn conversations, allowing for follow-up questions without losing context. 
  • Text-to-Speech (TTS) technology 
    TTS is what allows a voice bot to deliver responses in a human-like voice. Once the bot determines the response based on the user’s input, TTS synthesises the text into spoken language. High-quality TTS ensures that responses sound natural, making the interaction feel more engaging and personal. Many voice bots now offer customisable voices, accents, and even tones to align with brand identity, enhancing the user experience. 
  • Contextual awareness and memory 
    Advanced voice bots are designed to retain context within a conversation, enabling them to handle multi-step or complex queries without needing the user to repeat information. For example, if a user asks about account balance and then follows up with a question on recent transactions, a voice bot with contextual awareness can seamlessly address both. Some bots even have memory features, allowing them to retain information across sessions (within privacy boundaries), which adds personalisation and consistency to user interactions. 
  • Multilingual and cross-language capabilities 
    Modern voice bots often support multiple languages, making them suitable for global businesses serving a diverse customer base. These bots can detect the language a user speaks, adjust their responses accordingly, and even switch languages mid-conversation if needed. This feature is crucial for improving accessibility and ensuring that users from different regions or linguistic backgrounds receive effective support. 
  • Customisable personalities and tones 
    Voice bots can be tailored to align with a brand’s voice by adopting specific tones, personalities, and speech styles. This customisation makes interactions more on-brand and memorable, particularly in customer service scenarios. Whether a company prefers a friendly and casual voice or a formal and professional tone, voice bots can adapt to convey the desired personality. 
  • Integrations with backend systems 
    Voice bots are often integrated with a company’s Customer Relationship Management (CRM), Enterprise Resource Planning (ERP), or other backend systems, enabling them to pull data and perform actions in real time. This connectivity means a voice bot can instantly retrieve customer information, update records, or process requests based on the conversation. For example, a bank’s voice bot might pull recent transaction data, while a retail bot could track order statuses, improving the efficiency of the conversation. 
  • Speech analytics 
    Speech analytics goes beyond basic speech recognition by analysing conversation patterns, pauses, and other vocal markers that provide insight into the user experience. These insights are invaluable for improving bot performance, as they allow businesses to identify areas where users might get confused or frustrated. By applying speech analytics, companies can continuously optimise their voice bots for better accuracy and customer satisfaction. 

This combination of features allows voicebots to handle everything from simple FAQs to more complex requests that involve multiple steps or questions. Their main distinction from text-based chatbots is their voice interface, which allows for a hands-free experience—a significant advantage for customers in scenarios where typing isn’t practical.


How voicebots work

As described above, voicebots rely on advanced AI technologies, primarily Natural Language Processing (NLP), and they have a range of features and capabilities. With these capabilities, AI voicebots have become essential in today’s customer service landscape, supporting agents and helping maintain high service quality, no matter the scale. 

Here’s a quick breakdown of how they work in a real-world scenario: 

  • User interaction begins: A customer initiates a conversation with the voice bot by speaking a question or command, such as, "What’s the status of my order?" 
  • Audio captured and processed by ASR: The voice bot uses ASR to convert the spoken words into text. ASR processes the sound waves, filtering out background noise and interpreting the speaker's words with high accuracy. 
  • NLP and NLU interpret the query: With the transcribed text, the bot’s NLP system analyses the structure and identifies the key intent—determining that the customer is asking about an "order status." Through NLU, the bot detects that this request is a factual inquiry, not an emotional one, and prepares a suitable response. 
  • Database query or action Initiation: Based on the request, the voice bot might interact with other software systems or databases to retrieve information about the customer’s order status. This could involve a direct database query or an API call that accesses the needed data. 
  • Response generated: Once the information is retrieved, the bot formulates a response, such as, "Your order is currently being prepared and will be dispatched by tomorrow." 
  • Text-to-Speech (TTS) converts text to voice: Finally, the TTS system transforms the text-based response into spoken words, enabling the bot to "speak" back to the customer in a natural voice. 
  • Follow-up interaction: If the user has additional questions, the voice bot can continue the conversation, maintaining context and memory of the previous interaction. For example, if the customer asks, "Can I change my delivery address?" the bot can retain the order details from the initial query and respond appropriately. 

This allows AI voicebots to deliver accurate and immediate responses, making them ideal for businesses looking to optimise their customer support with minimal human involvement. 

Voicebot vs. IVR: What's the difference?

Interactive Voice Response (IVR) and voicebots are two popular technologies, each serving a different purpose. Knowing the differences can help businesses decide the best approach to enhance customer experience (CX). Let’s break it down: 

AI voice bot vs. IVR

Traditional IVR.
If you've ever called a business and been greeted by a voice saying, “Press 1 for English,” then you’ve navigated through an IVR menu. Traditional Interactive Voice Response (IVR) systems allow callers to navigate through a series of pre-recorded voice menus using their phone's keypad or voice commands. An IVR greets the caller with a recorded message and presents several menu options. These systems are often used by businesses and are familiar to most customers.  

While IVRs offer certain benefits for contact centres, such as handling high call volumes and providing basic information, the technology has limitations that may not meet modern customer expectations. Some challenges of IVRs include: 

  • Impersonal communication: Interactions can feel robotic and disengaging, leading to customer frustration. 
  • Complex menu options: Long, convoluted menus can confuse callers, making it difficult for them to reach the information they need. 
  • Long hold times: Customers may find themselves waiting on hold if they require assistance beyond what the IVR can offer, leading to dissatisfaction. 

AI voicebots.
In contrast, AI voicebots are designed to create a more conversational, dynamic, and user-friendly interaction. Voicebots are essentially supercharged IVRs, equipped with the intelligence to ‘think’ and integrate with customer databases to deliver an even better customer experience. 

Here’s how voicebots address the limitations of traditional IVR systems: 

  • Conversational interactions: Voicebots use advanced Natural Language Processing (NLP) to understand and respond to user inquiries in a more human-like manner. Instead of following rigid menu options, customers can ask questions naturally, making interactions feel more engaging and less mechanical. 
  • Dynamic responses: With the ability to learn and adapt, AI voicebots can handle a broader range of inquiries and context. They can provide tailored responses based on user data, leading to a more personalised experience. 
  • Seamless escalation: If a voicebot cannot resolve an issue, it can smoothly transition the customer to a human agent without the need for the customer to repeat information, significantly enhancing the overall customer experience. 

voice bot and IVR differences

Three differences between traditional IVRs and AI voicebots

So, what sets AI voicebots apart from traditional IVR systems? Here are three key differences between traditional IVRs and AI voicebots: 

  1. Understanding meaning and intent: AI voicebots truly shine in their ability to understand meaning and intent. Unlike traditional IVRs, which simply follow a script, modern voicebots grasp the context behind customer queries. This means they can cater to individual needs more effectively. For instance, if a customer sounds frustrated, the voicebot can quickly escalate the call to a human agent—helping to resolve issues before they escalate into negative experiences.
  2. Scalability and flexibility: AI voicebots handle complex queries and automate common interactions, freeing up your human support team for more intricate issues. IVR systems have limits; they can only guide users so far before running out of options, often leaving customers unsatisfied. With voicebots, you get a dynamic solution that delivers real answers and keeps your customers engaged.
  3. Intelligence: One major reason customers often find IVR systems frustrating is their lack of intelligence. These systems can feel rigid and impersonal, leaving customers feeling stuck on endless menus. With voicebots, callers can engage in genuine conversations instead of navigating through a maze of prompts. Powered by conversational or generative AI, voicebots respond naturally to inquiries, making interactions feel seamless and friendly. 

Benefits of AI voicebots and voice assistants in customer service

AI voicebots and voice assistants are changing the game in customer service, offering a range of benefits that can elevate business operations. Let’s explore the top advantages that come with implementing voicebot technology.
