System low speed encode the speech signal at a variable duration segment analysis

Abstract

In article, materials on research of a speech signal such properties, as uniformity (similitude) of the speech signal instant values distribution are stated. This property is used in a way of the speech processing segments allocation on the basis of the consecutive statistical analysis. The parameters of a linear prediction counted on each step of expansion undergo insignificant (within a quantization step) changes in relation to an initial segment. This circumstance allows to use results of the analysis of an initial site for restoration of the site expanded in the above-stated way that allows to lower essentially both computing complexity, and speed of a speech signal coding.
