Abstract
Disclosed in an embodiment of the present invention are a voice frequency signal processing method and device the voice frequency signal processing method in the embodiment comprising: when a voice frequency signal switches bandwidth acquiring an initial high frequency band signal corresponding to the current frame of the voice frequency signal; acquiring the time domain global gain parameter of the initial high frequency band signal; weighting an energy ratio and the time domain global gain parameter and using the obtained weighted value as a predicted global gain parameter the energy ratio being the ratio between the energy of a historical frame of the high frequency band time domain signal and the energy of the current frame of the initial high frequency band signal; utilizing the predicted global gain parameter to correct the initial high frequency band signal and acquiring a corrected high frequency band time domain signal; synthesizing a current frame of narrow frequency band time domain signal and the corrected high frequency band time domain signal and outputting the synthesized result.
