Abstract  Abstract

The present invention discloses a method and apparatus for processing a voice / audio signal. In an embodiment, a method of processing a speech / audio signal comprises: obtaining an initial high frequency band signal corresponding to a speech / audio signal of a current frame when the speech / audio signal is switched over bandwidth; Obtaining a time domain global gain parameter of an initial high frequency band signal; Performing a weighting process on the energy ratio and the time domain global gain parameter and using the obtained weighted value as the predicted global gain parameter, wherein the energy ratio is calculated by multiplying the energy of the high frequency time domain signal of the history frame and the initial high frequency signal of the current frame Energy ratio; Correcting the initial high-frequency signal using the predicted global gain parameter to obtain a corrected high-frequency time-domain signal; Synthesizing the narrow frequency time domain signal of the current frame and the corrected high frequency time domain signal, and outputting the synthesized signal.
