Abstract (en)
[origin: EP0428445A1] 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. <IMAGE>
