Problems solved by technology

However, the above-mentioned echo cancellation method cannot solve the nonlinear distortion problem of the loudspeaker. The nonlinear distortion of the loudspeaker is manifested in the output of the loudspeaker. There are many additional distortion signals of non-original speech signals. The distortion The signal is a nonlinear distortion signal caused by the nonlinear distortion of the loudspeaker, and the existing echo cancellation system cannot effectively process the nonlinear distortion signal, thereby affecting the quality of voice communication

Abstract

The invention discloses a voice signal processing method, a processing device, a terminal and a storage medium thereof. The voice signal processing method comprises the following steps of: acquiring afirst voice signal, acquiring a second voice signal of echo generated when the first voice signal is played, performing echo processing on the second voice signal to obtain a residual signal corresponding to the first voice signal, and performing suppression adjustment on the first voice signal according to the relevancy between the first voice signal and the residual signal. According to the scheme provided by the embodiment of the invention, echo processing is carried out on the second voice signal to obtain the residual signal corresponding to the first voice signal, therefore, the severity degree of the nonlinear distortion signal in the echo can be judged according to the relevancy between the residual signal and the first voice signal, that is, the first voice signal can be suppressed and adjusted according to the relevancy between the first voice signal and the residual signal, the nonlinear distortion signal emitted by the loudspeaker can be suppressed, and the quality of voice communication is improved.

Description

technical field [0001] The embodiments of the present application relate to the technical field of voice signal processing, and in particular, to a voice signal processing method, a processing device, a terminal, and a computer-readable storage medium thereof. Background technique [0002] With the continuous development of voice signal processing technology, users have higher and higher requirements for voice quality. If there is an echo in the voice, the voice quality will be seriously affected. The principle of echo generation: the voice signal is played in the speaker and undergoes multiple reflections in a closed or semi-closed environment, resulting in signal distortion, and finally collected by the microphone together with the local voice to form an echo. [0003] In order to eliminate the impact of the echo on the voice quality, the traditional echo cancellation method is mainly to directly perform echo cancellation on the voice signal collected by the microphone thr...
