Abstract  Abstract

1. A method for processing a speech / audio signal, comprising the steps of: when switching a speech / audio signal from a wideband frequency signal to a narrowband frequency signal, the original high-frequency signal corresponding to the current frame of the speech / audio signal; receive a global parameter for amplifying the high-frequency signal in time areas in accordance with the slope of the spectrum of the current frame of the speech / audio signal and the correlation between the current frame of the narrowband frequency signal and the archive frame narrow frequency band signal; corrected initial frequency signal via the global gain parameter in the time domain to obtain a corrected high-frequency signal in the time domain; synthesizing the current frame of the narrowband signal in the time domain and the corrected high-frequency signal in the time domain and outputting the synthesized signal. 2. The method of claim 1, wherein in the step of obtaining a global parameter for amplifying a high-frequency signal in the time domain in accordance with a slope parameter of a current frame of a speech / audio signal and correlation between the current frame of the narrow-band frequency signal and the archive frame of the narrow-band frequency signal: relate the current frame of the speech / audio signal to the first type of signal or the second type of signal in accordance with the slope of the spectrum of the current frame of the speech / audio signal and the correlation between the current frame narrow shines frequency signal and archival frame narrowband frequency signal, when the current frame is a speech / audio signal is the first type signal
