ABSTRACT:
A transmission system includes a speech decoder, the speech decoder having a detector which determines a level of background noise in a speech signal and a post filter in electrical communication with an output of the decoder when the level of the background noise is equal to or less than a threshold value. A synthesis filter is connected to the output when the level of the background noise is greater than the threshold value.
