What is Voice bot?

A voice bot, also known as a conversational voice agent or voice assistant, is an advanced AI system that communicates with users through spoken language. Voice bots can be integrated into various applications, devices, and platforms, providing a convenient experience for users.
Voicebot operates using below technologies:

  • Natural Language Understanding (NLU)
  • Natural Language Processing (NLP)
  • Machine learning
  • ASR (automatic speech recognition)
  • TTS (Text to Speech)

When the user speaks something, ASR converts the speech into text and the converted text is understood through NLP (natural language processing). Then the appropriate answer is formulated and converted into speech using Text to Speech (TTS) and the user gets an appropriate response for the query.

Voicebot understands user queries with the help of artificial intelligence and responds to the user. Voicebots have multiple benefits to customers and businesses; for instance, in contact centers, the user needs to go through interactive voice response(IVR) by pressing keys as per the instructions; unlike IVRs, the customers can talk in natural, human language with voicebots.

With time, the application of Voicebots is increasing - Voicebots are not limited to just virtual voice assistants, such as Alexa, Siri, or Google Assistants.

Some contact centers, for instance, have deployed Voicebots instead of human agents to converse with customers.

Types of voice bot

According to the application, voice bots can be bifurcated as below:

Voicebot integrated with a contact center for Inbound and Outbound call automation   

AI Voice bot integrated with the contact center uses AI-based 2-way conversational voice as a medium to communicate with the customer. It can automate inbound and outbound calls without any human intervention. It can also transfer the call to a human agent upon the customer’s request. Voicebot can be implemented as per the industry-specific use cases.

Use Cases of Inbound Calls 

  • Customer Support  
  • Sales Inquiries 
  • Customer Inquiries 
  • Employee IT Helpdesk  
  • Lead Qualification  
  • Customer Engagement  
  • Insurance Renewal  
  • Claims FNOL Insurance Filing  
  • Claim Status Enquiry  
  • Investigation & Verification  
  • Claim Settlement and More  


Use Cases of Outbound Calls 

  • Automate Tele-Marketing Calls   
  • Payment & renewal reminder 
  • Debt collection 
  • Cross-sell and upsell   
  • Marketing automation 

Nowadays, providing WhatsApp support has become mandatory for businesses; businesses want to connect through their favorite channels, and WhatsApp is one of them. And that can be easily achieved by implementing WhatsApp voicebot.

Whatsapp allows users to send voice inputs or voice commands to the bot. In reply, users can get text, voice, or both.
The Floatbot platform allows you to set user responses in text and voice. For instance, if the bot detects voice-based input, then the bot will answer with voice + text. You can also set it to a single response form, i.e., text or voice. 

Chatbot with Voice AI  

A chatbot with voice AI is a chatbot that can accept voice as input. The user can use the microphone option available to ask their queries, and the bot can reply in chat+/voice form as the user requires. Floatbot allows voice-based input with streaming. Along with voice, the bot also accepts text inputs. The benefit of a Chatbot is that it can act as an AI-based voice virtual assistant and give replies in a chat-based rich format and voice.

Voicebots operate through a combination of various deep tech modules that include

Speech to text

The Speech Text or ASR (Automatic speech recognition) module converts the natural speech (audio spoken by the user) to text; it works fine even in noisy environments. The Speech to Text module is typically developed with end-to-end deep learning-based speech recognition. It can recognize and understand different accents and languages. 

NLP Engine

Once the spoken words are transcribed, the voicebot utilizes NLP to understand the meaning behind the words. NLP (Natural language processing) helps the system interpret and comprehend the user's intent, allowing it to respond appropriately.

Intent detection/LLMs

After the query is processed, intent gets detected, or the query is passed to LLMs for execution. Voicebots are trained to work on use-case-specific queries, and intent detection takes place when a query is encountered, or either query is passed to LLMs for execution.

Integration with backend systems

Voicebots are often integrated with backend systems or databases to fetch real-time information or perform specific tasks. This integration allows them to provide up-to-date and relevant responses.


Voicebots can become very useful for businesses across all industries as they can save the time required for customer service. Below are the industry-specific use cases in which voicebot can be implemented.  


  • Automated banking services

Before proceeding with the bank, a customer must get all the information related to banking services, such as loans, cheques, cards, etc., that can be provided over a voicebot called banking automation bot.

  • Customer support with intelligent assistants

If a user wants support over a call, then a voicebot automates the call and provides the desired response for the query; this would eliminate human support, saving time and money.

With the latest AI tech, getting voice authentication over a call is possible for security reasons. A voicebot created using Floatbot’s platform allows adding voice biometrics that make a voicebot safe and secure for banking purposes.

  • Improved customer interactions with native languages

The multilingual capabilities of a voice bot enable users to interact in native languages. This makes customer interaction smooth and comfortable with a bot.


  • Automated sales journey

A voicebot can replace a traditional way of filling out an insurance policy form in a more interactive manner that helps a user save time filling out a lengthy list of questions for a policy. With the more accessible and interactive approach, the sales journey becomes more robust, resulting in more conversations through a voicebot.

  • Automated claims FNOL process.

With the traditional approach for the FNOL process, a customer calls the insurance company and talks to their agent, and provides all the information; if the agents are busy, then the customer needs to wait. Meanwhile, with the voicebox, there is no waiting time for the customers, and for the company, it becomes an automated process, saving the costs and time of their agents.

  • Customer support

An emergency can occur at a time in the insurance sector, and a voicebot is an AI automation tool. Hence, it is available 24/7 for customers to answer their queries anytime. It answers the queries and connects to a human agent when required.

  • Lead generation

Generating leads is a tedious and endless task for a sales team; if they adopt the power of artificial intelligence by implementing a voice bot, this task can become smoother and more interactive. Whenever a salesperson calls a prospect, either the prospect is uninterested or will not take the call seriously. But if a voicebot calls the prospect, it grabs their attention, and a prospect would like to know more about the call and the offer.


With the development of Artificial Intelligence, voicebots will play a crucial role in the automation of various essential areas for a business. The primary trend we will see in 2024 is the combination of voice and chat as one conversational AI tool for automation.
