<p>The method consists in subdividing (1) the speech signal into packets of a given number of frames of constant duration, by sampling a given number n of energy values from each frame, in quantifying (2, 3, 4) the first energy value measured in each first frame of a packet according to a given number QO of bits, and the variations in the k-1 remaining energies relative to the first value of the energy sampled on a given number Q1 of bits less than QO, the variations in the k-1 energies being selected from a list of "slopes", making it possible to attribute to each energy sample k the energy "slope" which separates it from the energy of the preceding sample k-1. Applications: vocoders. <IMAGE></p> |
