CA 2306098

Sound source information is coded in multimode using static and dynamic features of quantized volcal-tract parameters, and multimode post-processings are carried out even by the decoder, thus improving the quality in the non-speech section and the steady noise section.

On effectue un codage multimode d'informations sonores sources à l'aide des caractéristiques statiques et dynamiques de certains paramètres du tractus aérien quantifiés, et on procède à plusieurs traitements multimodes ultérieurs au moyen d'un décodeur, de manière à améliorer la qualité de la partie non vocale et de la partie bruit stable.
