Abstract
A method of coding and decoding speech for voice communications using a vocoder with very low bit rate includes an analysis part for the coding and the transmission of the parameters of the speech signal and a synthesis part for the reception and the decoding of the parameters transmitted and the reconstruction of the speech signal. The method comprises: grouping together the voicing parameters, pitch, gains, LSF coefficients over N consecutive frames to form a superframe, and performing a vector quantization of the voicing information in the course of each superframe by formulating a classification using the information on the chaining in terms of voicing existing over 2 consecutive elementary frames.
