Abstract  Abstract

Embodiments of the present invention describe a speech / audio signal processing method and apparatus. In one embodiment, the speech / audio signal processing method includes: obtaining an initial high frequency signal corresponding to an existing speech / audio signal frame when a speech / audio signal transitions its bandwidth; obtaining a time-domain global gain parameter of the initial high frequency signal; performing weighting operations on the energy ratio and time-domain global gain parameter, and using a obtained weighted value as a predicted global gain parameter; wherein the energy ratio is a ratio between the energy of the historical frame of the high frequency time-domain signal and the energy of an existing frame of the initial high frequency signal; correcting the initial high frequency signal using the projected global gain parameter to obtain a corrected high frequency time-domain signal; and synthesizing an existing frame of the narrow frequency time-domain signal and the corrected high frequency time-domain signal and extracting the synthesized signal.
