ABSTRACT:
A method of breaking up a vocal signal into binary frames of a predetermined duration. The frames are grouped together in packets of successive frames by associating a predictive filter with each frame of a packet. Furthermore, the coefficients of each predictive filter are quantified by taking into account the stable or non-stable configuration of the vocal signal.
