Abstract:
1. A processor operable to execute a set of instructions stored in a storage medium to produce a set of quantized speech frame parameters, the parameters comprising: a predictively quantized pitch lag value; a quantized target error vector of amplitude components; predictively quantized phase values; and a quantized target error vector of linear spectral information components, wherein the pitch lag value, the amplitude components, the phase values, and the linear spectral information components have been extracted from a voiced speech frame, wherein the quantized pitch lag value δ wherein the values L m , L m . . . , L m are the pitch lags for frames m 1 , m 2 , . . . , m N , respectively and the values η m , η m , . . . , η m are weights corresponding to frames m 1 , m 2 , . . . , m N , respectively.
