Abstract:
The present invention discloses a speech/audio signal processing method and apparatus. In an embodiment, the speech/audio signal processing method includes: when a speech/audio signal switches bandwidth, obtaining an initial high frequency signal corresponding to a current frame of speech/audio signal; obtaining a time-domain global gain parameter of the initial high frequency signal; performing weighting processing on an energy ratio and the time-domain global gain parameter, and using an obtained weighted value as a predicted global gain parameter, where the energy ratio is a ratio between energy of a historical frame of high frequency time-domain signal and energy of a current frame of initial high frequency signal; correcting the initial high frequency signal by using the predicted global gain parameter, to obtain a corrected high frequency time-domain signal; and synthesizing a current frame of narrow frequency time-domain signal and the corrected high frequency time-domain signal and outputting the synthesized signal.

Claim (Index 17):
The non-transitory computer-readable medium according to  claim 16 ,\n wherein the limiting the spectrum tilt parameter to less than or equal to the first predetermined value to obtain the first limited spectrum tilt parameter value comprises: setting a value of the spectrum tilt parameter as the first limited spectrum tilt parameter value when the value of the spectrum tilt parameter is less than or equal to the first predetermined value; and setting a first predetermined value as the first limited spectrum tilt parameter value when the value of the spectrum tilt parameter is greater than the first predetermined value.
