Abstract
A signal including speech and background noise is encoded by first decomposing the signal into speech and noise components. A first speech encoding algorithm is then used to generate codebook indices for the speech component and a second algorithm is applied to generate codebook indices for the noise component. The speech encoding algorithm performs better since it faces clean speech, while a simple, very low bit rate algorithm may be used to encode the noise.
