Audible error detector and controller utilizing channel quality data and iterative synthesis

An apparatus comprising:

• a channel decoder (44), responsive to an encoded signal received over a transmission channel (42), for providing a channel-decoded signal (46);
• an iterative processor (52), responsive to the channel decoded signal (46), for providing a synthesized speech signal (54) and for providing a modification command signal (60);
• and
• a synthesized signal modifier (58), responsive to the synthesized speech signal (54) and to the modification command signal (60), for providing a synthesized output signal (62) meeting typicality standards which vary with channel quality deficiency.

A method comprising the steps of:

• providing a channel-decoded signal (46) in response to an encoded signal received over a transmission channel (42);
• executing an iterative signal processing step, in response to the channel-decoded signal (46), for providing a synthesized speech signal (54) and for providing a modification command signal (60);
• and
• providing a synthesized output signal (62) meeting typicality standards which vary with channel quality deficiency, in response to the synthesized speech signal (54) and also in response to the modification command signal (60).
