Verfahren und Einrichtung zur Codierung von Prädiktionsfiltern in Vocodern mit sehr niedriger Datenrate.

摘要

The method consists in dividing the voice signal into binary frames of specified duration in order to group them (121 ... 123) into packets of successive frames while associating a predictive filter with each frame of a packet and in quantifying (181 ... 183) the coefficients of each predictive filter taking account (20, 21) of the stable or unstable configuration of the voice signal. …Application: speech encoding. ……
