What is IVR

Interactive voice responses (IVR) menus allows you to interact with your users through a voice call. You will be able to play a series of voice dialogs and your users will be able to respond via their telephone keypad. A common use case is a Customer Helpline where you might hear:

“For sales enquiry, please press 1. For technical support, please press 2. To speak to our customer service officers, please press 0.”

Hoiio’s IVR API allows developers to easily create IVR menus like the above using RESTful APIs. This can be achieved without the need for technical telecommunication knowledge. Coupled with our Hoiio Numbers and Text-to-Speech (TTS) technology, you can get started instantly without hassle.

Read An Overview

IVR is our most powerful set of APIs, consisting of a couple of simple building blocks.

Building an IVR application will usually use 1 or more of the building blocks, and issuing the API requests one after another. It is not the usual request-and-thats-it-API, hence we want to make sure you read An Overview of IVR first.
