Title:
A VOICE SIGNAL PROCESSING METHOD AND DEVICE
Document Type and Number:
WIPO Patent Application WO/2009/115032
Kind Code:
A1
Abstract:
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.
