Abstract  Abstract

Voice / Audio Signal Processing Method and Apparatus Embodiments of the present invention disclose a voice / audio signal processing method and apparatus. In one embodiment, the voice / audio signal processing method includes: when an alternating band voice / audio signal, obtaining an initial high frequency signal corresponding to a current voice / audio signal frame; obtaining a time domain global gain parameter of the initial high frequency signal; performing weighting processing on an energy ratio and the time domain world gain parameter, and using a weighted value obtained as a global gain parameter, where the energy ratio is a relationship between the energy of a historical signal frame in the domain of high frequency time and energy of a current high frequency initial signal frame; rectifies the initial high frequency signal using the predicted global gain parameter to obtain a corrected high frequency time domain signal; and synthesizing a current signal frame in the narrow frequency time domain and corrected high frequency time domain signal and outputting the synthesized signal.
