IVR can also refer to systems that provide information in the form of recorded messages over telephone lines, in response to user-supplied input in the form of spoken words or, more commonly, Dual-Tone Multi Frequency (DTMF) signaling. Examples include banks that enable you to check your balance from any telephone, and automated stock-quote systems. For example, For checking account information, press 1 or If you want a stock quote, press 2.
A computer technology that enables users to connect to a computer system and obtain information through voice input, instead of by using a keypad, keyboard, or touch-tone telephone device. An IVR system responds to a human voice, looks up information, presents alternatives, and interacts with the caller.
