Conversational IVR - 6 Best Software Platforms in 2021

What Is Conversational IVR?


Conversational IVR (Interactive Voice Response) is a system where the customer speaks to a machine on the phone and the machine understands what the customer wants.

In such a case the customer speaks on the phone like they would speak to another human. The customer’s speech is transcribed into text through a technology called ASR (Automated Speech Recognition). That text is then analyzed by Conversational AI intent detection mechanism, which essentially determines what the customer wants (e.g. info about a product, know the opening hours, status of their package etc). Then the answer for the customer question is made from text to speech (TTS) and the answer is played to the customer as voice.

The benefit of Conversational IVR is that customers do not need to make multiple choice selections but can simply ask their questions on the phone and the software provides them with an answer.

Conversational IVR consists of three main parts - ASR, intent detection and TTS. To build a Conversational IVR you can use vendors that provide all three or combine a Conversational AI based intent detection solution and connect ASR and TTS from other vendors. 

Below we have highlighted the top vendors for Conversational IVR software platforms.
