ABSTRACT:
The invention provides a speech coding system with input signal transformation that may reduce or essentially eliminate “silence noise” from the input or speech signal. The speech coding system may comprise an encoder disposed to receive an input signal. The encoder ramps the input signal to a zero-level when a portion of the input signal comprises silence noise.
