Abstract  Abstract

The generation of multipulse excitation codes by digitizing an original speech partitioning the digitized signal into a number of samples pre-emphasizing the samples producing linear predictive reflection coefficients from said samples quantizing these reflection coefficients converting the quantized reflection coefficients to spectral coefficients and subjecting the spectral coefficients to pitch analysis to obtain a spectral residual signal.
