Echo cancellation system, method, device and equipment and storage medium

Abstract

The invention discloses an echo cancellation system, method, device and equipment and a computer readable storage medium. The system includes a signal processing module, a power amplifier module, a loudspeaker, a signal processing module and a sound collection module. The signal processing module is connected with the power amplifier module and used for transmitting a first playing signal to the power amplifier module, the power amplifier module is connected with the loudspeaker and used for receiving the transmitted first playing signal, processing the first playing signal to generate a second playing signal, and transmitting the second playing signal to the loudspeaker and the signal processing module, the loudspeaker is used for receiving and playing the second playing signal, the signal processing module is used for receiving and storing the second playing signal, the sound collection module is connected with the signal processing module and used for collecting the sound signal andtransmitted the sound signal to the signal processing module, the signal processing module is used for receiving the sound signal, the sound signal is subjected to noise reduction treatment accordingto the second playing signal, an echo cancellation signal is generated, and thoroughness of the echo cancellation is ensured.

Description

technical field [0001] The present invention relates to the field of sound processing, in particular to an echo cancellation system, method, device, equipment and computer-readable storage medium. Background technique [0002] During the communication between the communicating parties using speaker and microphone communication systems, in the case of using these systems, the speaker of the communicating party's communication device first outputs the voice of the communicating party, which comes from the communicating party's communication device. The voice of the other party outputted by the speaker of the communication device of the party of the call is picked up again by the microphone of the communication device of the party of the call, and sent to the communication device of the party of the call. The speaker of the communication device of the communication party outputs the voice of the communication party picked up at the side of the communication party. When such a ...

Problems solved by technology

[0004] However, in the process of implementing the present invention, the inventor found that: due to the processing of the power amplifier itself, there may be nonlinear distortion, so that the playback signal output by the power amplifier to the speaker has nonlinear distortion, resulting in the echo still existing in the acquired echo cancellation signal. Incomplete echo cancellation, poor user experience
