What is an IVR?

Interactive voice response (IVR) is a technology that allows a computer to interact with humans through the use of voice and Dual-Tone Multi-Frequency (DTMF) dialing tones input via keypad.

IVR or interactive voice response is a phone technology that allows a computer to detect voice and touch tones using a normal phone call. The IVR system can respond with pre-recorded or dynamically generated audio to further direct callers on how to proceed. IVR systems can be used to control almost any function where the interface can be broken down into a series of simple menu choices.

The caller responds to the IVR by pressing digits on the telephone or speaking words or short phrases. Applications include bank-by-phone, flight-scheduling information and automated order entry and tracking.
