Abstract

The invention discloses an echo suppression processing method and device. The method comprises steps: sound data are acquired, wherein the sound data comprise first data and second data, the first data are the sound data transmitted to a second end by a first end, the second data are the sound data transmitted to a fouth end from a third end after the first data are transmitted to the second end,the first end and the third end are used for inputting the sound data, and the second end and the fourth end are used for playing the sound data; the sound data are processed according to a wavenet model, wherein the wavenet model is pretrained for removing or weakening data related to the first data from the second data; and the output sound data are acquired from the wavenet model. Thus, the problems of low accuracy and poor echo suppression effects of an echo cancellation algorithm in a related technology can be solved.

Description

technical field [0001] The present application relates to the field of echo processing, and in particular, to an echo suppression processing method and device. Background technique [0002] The echo generated by network transmission can be roughly divided into two types, namely circuit echo and acoustic echo. In the teleconferencing system, the acoustic echo is unavoidable, and the generation process of the acoustic echo is as follows: [0003] Such as figure 1 As shown, in the conference call process, the sound signal sent by the speaker at the A terminal is converted by the microphone, and then transmitted to the B terminal through the intermediate transmission process, and then broadcast by the speaker of the B terminal. At this time, the sound played by the speaker at the B end will be received by the microphone at the B end, and then transmitted back to the speaker at the A end, and played by the speaker at the A end. At this time, the speaker at the A end hears the ...
