Problems solved by technology

At this time, the first terminal will play the voice of the second terminal user and superimpose the first terminal user's own voice, which affects the normal call quality
[0004] The echo cancellation technology for acoustic echo is called Acoustic Echo Cancellation (AEC). The traditional AEC algorithm depends on the hardware characteristics of both ends of the call, and needs to be configured for each device model. The effect is unstable, and new devices emerge in endlessly. , to adapt to various new devices, it takes a lot of testing time and the cost is very high

Abstract

The invention discloses a communication method and device. The method includes: receiving the first-end audio, collecting the second-end audio, the second-end audio is mixed with the echo of the first-end audio, and determining the difference between the first-end audio and the second-end audio matching the target audio, canceling the echo in the audio of the second end according to the target audio, generating echo cancellation audio, and sending the echo cancellation audio to the first end. In the above method, through matching, the target audio to be referenced when performing echo cancellation is dynamically determined, and it is not necessary to configure for each device model, which avoids the problem of unstable echo cancellation effect caused by static configuration parameters, and reduces the cost of adapting various new devices. It consumes a lot of testing time and reduces the adaptation cost.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a communication method, a communication device, an electronic device and a computer-readable storage medium. Background technique [0002] Two-way voice calls can produce acoustic echo, which is caused by multiple feedbacks from the speaker to the microphone in hands-free or conferencing applications. [0003] The voice signal of the first terminal user is transmitted to the room where the second terminal is located. Due to spatial reflection, an echo is formed and input from the microphone of the second terminal again, and the voice signal of the second terminal user is superimposed. At this time, the first terminal will play the second terminal user's voice and superimpose the first terminal user's own voice, which affects the normal call quality. [0004] The echo cancellation technology for acoustic echo is called Acoustic Echo Cancellation (AEC). The tradition...
