Changing iPhone DTMF Tones to Work with Some IVRs
Authored by: AriX on Mar 01, '11 04:32:13PM

IVR is not voice recognition, as crarko suggests. It's just the opposite. An IVR is basically when you call and it says "press 1 for this, press 2 for that, etc.". So the technology here is that the IVR is recognizing the DTMF tones (the different beeps you hear when you press different digits) so that it knows what button you pressed, not that it is "allowing verbal commands" or anything.

Actually, it is both - voice and DTMF recognition.

Fair enough! However, in this instance, we are explicitly referring to the DTMF tones.
