Abstract  Abstract

FIELD: physics.SUBSTANCE: method for processing a speech/audio signal includes the stages, at which the starting high frequency signal is received upon switching the transmission band of the speech/audio signal corresponding to the current frame of the speech/audio signal; the global gain parameter of the high frequency source signal is received in the time domain; weight processing is performed for the ratio of energy and the global gain parameter in the time domain, and the obtained weighted value is used as a predicted global gain parameter, wherein the energy ratio is a ratio between the energy of the high frequency signal archival frame in the time domain and the energy of the current high-frequency source signal frame; the high frequency source signal is corrected with the predicted global gain parameter to obtain the corrected high-frequency signal in the time domain; the current frame of the narrowband signal in the time domain and the corrected high-frequency signal in the time domain are synthesized, and the synthesized signal is output.EFFECT: providing comfortable sound reproduction while switching the transmission band of the speech/audio signal.23 cl, 10 dwg
