A method is given of encoding a speech signal using analysis-by-synthesis to perform a flexible selection of the excitation waveforms in combination with an efficient bit allocation. This approach yields improved speech quality compared to other methods at similar bit rates.

L'invention concerne un procédé permettant de coder un signal vocal en utilisant l'analyse par synthèse pour réaliser une sélection souple des formes d'ondes d'excitation et dans le même temps, une affectation efficace des bits. Cette approche permet d'obtenir une qualité de parole comparable à celle obtenue par d'autres procédés à débits binaires similaires.
