Abstract  Abstract

FIELD: information technology.SUBSTANCE: invention relates to means of processing speech/audio signal. Method of processing speech/audio signal comprises steps of when switching bandwidth speech/audio signal is obtained initial high-frequency signal corresponding to the current frame of the speech/audio signal; obtaining global amplification parameter of the initial high-frequency signal in the time domain; weighing is for the ratio of energy and global amplification parameter in the time domain and used obtained suspended value as the predicted global amplification parameter, wherein the ratio of energy represents ratio between energy archive frame of high-frequency signal in time domain and energy of the current frame of the initial high-frequency signal; correcting the initial high-frequency signal using the predicted global amplification parameter for obtaining corrected high-frequency signal in the time domain; and the synthesised current frame of narrow-band signal in time domain and corrected high-frequency signal in time domain and a synthesised signal.EFFECT: technical result consists in provision of comfortable sound reproduction when switching speech/audio signals bandwidth.23 cl, 10 dwg
