A voice signal processing method includes: obtaining background noise frames (101); setting energy attenuation gain value to a background noise signal corresponding to a background noise frame obtained after an erasure concealment frame, so that difference of a energy attenuation gain value of a background noise signal corresponding to the background noise frame, and the energy attenuation gain value of the signal corresponding to the last frame lies in a threshold value area (102); and controlling energy attenuation of the background noise corresponding to the noise frame with the energy attenuation gain value (103). A voice signal processing device corresponding to the voice signal processing method is also provided.

L'invention concerne un procédé de traitement de signal vocal consistant à : obtenir des trames de bruit de fond (101); régler une valeur de gain d'atténuation d'énergie sur un signal de bruit de fond correspondant à une trame de bruit de fond obtenue après une trame de dissimulation d'effacement, de sorte que la différence d'une valeur de gain d'atténuation d'énergie d'un signal de bruit de fond correspondant à la trame de bruit de fond et la valeur de gain d'atténuation d'énergie du signal correspondant à la dernière trame se trouve dans une zone de valeur seuil (102); et réguler l'atténuation d'énergie du bruit de fond correspondant à la trame du bruit au moyen de la valeur de gain d'atténuation d'énergie (103). L'invention concerne également un dispositif de traitement de signal vocal correspondant au procédé de traitement de signal vocal.
