A wideband speech encoder according to one embodiment includes a filter bank having a lowband processing path and a highband processing path. The processing paths have overlapping frequency responses. A first encoder is configured to encode a speech signal produced by the lowband processing path according to a first coding methodology. A second encoder is configured to encode a speech signal produced by the highband processing path according to a second coding methodology that is different than the first coding methodology.

L'invention concerne, dans une forme de réalisation, un codeur vocal à large bande qui comprend un banc de filtres comportant un chemin de traitement en bande basse et un chemin de traitement en bande haute. Les chemins de traitement présentent des réponses en fréquences chevauchantes. Un premier codeur permet de coder le signal vocal produit par le chemin de traitement en bande basse selon une première technique de codage. Un deuxième codeur permet de coder le signal vocal produit par le chemin de traitement en bande haute selon une deuxième technique de codage, différente de la première.
