Abstract  Abstract

A voice / audio signal processing method, comprising: when a voice / audio signal switches from a wide frequency signal to a narrow frequency signal, obtaining an initial high frequency signal corresponding to a current signal frame of voice / audio; obtaining a time domain global gain parameter of the initial high frequency signal; carry out weighting processing on an energy ratio and the time domain global gain parameter, and use a weighted value obtained as a predicted global gain parameter, where the energy ratio is a ratio between the energy of a high-frequency time domain signal of a historical frame and the initial high-frequency signal energy of the current frame; correcting the initial high frequency signal using the global gain predicted parameter to obtain a high frequency time domain corrected signal; and synthesizing a narrow frequency time domain signal from the current frame and the high frequency time domain corrected signal and providing the synthesized signal.
