Problems solved by technology

For example, the uplink output volume was adjusted very low at the beginning, so the far-end user could not hear the uncontrolled echo, but the side effect is that the far-end user cannot hear the sound of the near-end user at this time, which affects the user experience.
After a period of time, the volume will gradually return to normal, but the remote user will wonder why the volume always slowly enters the normal working state

Abstract

The embodiment of the invention provides a method, device and equipment for controlling an echo suppressor, and a storage medium. The method comprises the steps: obtaining a training state or convergence state of an adaptive filter in the echo suppressor, wherein the adapter filter is used for performing the echo elimination training from the training state to the convergence state according to the voice information; switching an audio output suppression law in the echo suppressor according to the training state or the convergence state, wherein the audio output suppression laws correspondingto the training state and the convergence state of the adaptive filter are different. According to the embodiment of the invention, the method can achieve the corresponding adjustment of the audio output suppression laws of the echo suppressor according to the difference of the states of the adaptive filter, and can optimize the audio output effect of the echo suppressor.

Description

technical field [0001] Embodiments of the present invention relate to audio signal processing technologies, and in particular, to a control method, device, equipment and storage medium for an echo suppressor. Background technique [0002] Two-way real-time communication terminals, such as mobile phones, Bluetooth headsets, Bluetooth speakers, and tablet computers, etc., during the real-time communication process, the local microphone will naturally record the voice of the opposite end played by the speaker or speaker, and the echo formed will be sent back to the The opposite end, so that the remote user can hear what he just said, affecting the conversation experience. Therefore, an effective echo suppressor is needed in the communication terminal to eliminate the echo. [0003] Existing echo suppressors generally include adaptive linear filters to deal with rapidly changing acoustic echoes. Adaptive filters require a certain amount of training time to actually take effect...
