METHOD FOR SEPARATION OF QUASI-STATIONARITY SEGMENTS IN PROCESS OF SPEECH SIGNAL ANALYSIS IN VOCODERS WITH LINEAR PREDICTION Russian patent published in 2010 - IPC G10L19/00 

Abstract RU 2400831 C1

FIELD: information technologies.

SUBSTANCE: separation of quasi-stationarity segments in analysis of speech signal in vocoders with linear prediction is based on change of their duration in compliance with classification of speech segments and calculation of the main tone frequency.

EFFECT: improved accuracy of coding and reduced required speed of transmission.
