What are the voice AI agents?

A voice AI agent is also known by a few other names which are ai voice bot, ai call agent etc.. It is a conversational software entity that combines abilities like speech recognition, emotional intelligence, and natural language processing to interact with humans via the medium of voice. 

The Evolution: Beyond Chatbots and IVR 

In order to understand voice AI, we must clearly understand how it came to be in the position as of now:

  • Traditional IVR: These systems are entry-level and more rigid compared to the new innovations. Here, the caller gets greeted by a preset greeting and navigates by pressing keypad options as prescribed.
  • Chatbots: They are text based applications that lack the human feel and urgency that can be felt in a phone call problem resolution.
  • Voice AI agents: They are a more sorted form of agents who can analyze the situation, take appropriate decisions in routine tasks and solve issues without further escalation.

how Voice AI Agents works

The conversational AI voice system relies on three important factors:

  • Speech to text: The system transcribes the caller’s speech to text form.
  • LLM: With the help of large language models, the system understands intent, sentiment, and context using NLP.
