ABSTRACT:
When a communication channel is noisy, speech signals at the transmitter are converted by a speech recognition unit to data-reduced code words which are then transmitted repeatedly as redundant data so as to fill the available bandwidth. At the receiver, the redundant signals are converted to drive a speech generator.
