Abstract:
A speech compression system for processing a speech signal, the speech compression system comprising:an encoding system operable to select a rate for encoding the speech signal as a function of characterization of the speech signal, the encoding system operable to select a type classification, comprising one of a first type and a second type, the encoding system operable to encode the speech signal as a function of the rate and the type classification when a first rate is selected, the encoding system operable to encode the speech signal as a function of the rate, regardless of the type classification, when a second rate is selected; and the encoding system operable to encode an adaptive codebook gain and a fixed codebook gain when the first rate is selected and the type classification is the second type, where the adaptive codebook gain is encoded exclusive of the fixed codebook gain.
