Abstract

The embodiment of the present invention discloses a sound signal processing method, device, and storage medium; the method collects sound signals, and the sound signals include sound output signals of multiple different channels currently output, and sound input signals currently input, based on each The sound output signal and filter parameters corresponding to each channel, the echo signal corresponding to each channel is estimated, based on the echo signal, the echo cancellation process is performed on the sound input signal, and the residual signal is obtained. From multiple different sound output signals of the sound output signal Determine the target channel to be processed in the channel, adjust the current filter parameters corresponding to the target channel based on the residual signal, and return to the step of collecting the sound signal until no sound output signal is collected. This solution can effectively cancel the echo.

Description

technical field [0001] The present application relates to the field of signal processing, in particular to a sound signal processing method, device and storage medium. Background technique [0002] With the development of technology, users have higher and higher requirements for voice interaction. In the process of voice interaction, the voice sent by the speaker to other people through the voice interaction device returns to the echo signal generated in the receiver, which will have a serious impact on the voice interaction. Therefore, echo cancellation needs to be performed during voice interaction. [0003] Due to the diversity of voice interaction devices and the wide range of voice interaction applications, echo cancellation cannot be effectively performed. Contents of the invention [0004] Embodiments of the present application provide an audio signal processing method, device, and storage medium, which can effectively perform echo cancellation. [0005] An embod...
