A method, device and computer-readable medium for eliminating voice echo

Abstract

The invention discloses a method, device and computer-readable medium for eliminating voice echo, and belongs to the technical field of artificial intelligence. The method includes: obtaining a sequence of speech signals to be tested, the sequence of speech signals to be tested includes a plurality of continuous speech signals, and the speech signals carry the time points at which the speech signals are generated; using a speech echo classification model to predict the sequence of speech signals to be tested to obtain the echo The start time point and the echo end time point; based on the echo start time point and the echo end time point, remove a plurality of voice signals from the echo start time point to the echo end time point from the speech signal sequence to be tested, and generate no Echo of the speech signal sequence. Thus, the voice echo in the voice signal sequence can be effectively eliminated; moreover, the method for eliminating voice in the embodiment of the present invention supports a variety of voice scenes and has universal applicability. , and the problem that the software method is not universal.

Description

technical field [0001] The present invention relates to the technical field of artificial intelligence, in particular to a method, device and computer-readable medium for eliminating voice echo. Background technique [0002] Voice is very important information in cloud video conferencing. However, due to the uncertainty of the network environment and objective factors such as the physical environment, abnormal voice echoes often occur in cloud video conferencing, which affects the quality and quality of cloud video conferencing. The cloud video conferencing platform has a relatively large negative impact. Echo cancellation is of great benefit to improving the high availability of the cloud video conferencing system, as well as the quality and efficiency of the cloud video conferencing. [0003] Existing echo solutions have a hardware aspect as well as a software aspect. For example, a canceling device for far-field speech echo; the canceling device includes an echo canceli...

AI Technical Summary

Problems solved by technology

For example, a canceling device for far-field speech echo; the canceling device includes an echo canceling device body, a lifting mechanism, and a moving and rotating mechanism. Although the canceling device can effectively eliminate far-field echoes, the use of hardware will increase the cost of echo cancellation , cannot be fully accepted by users

For another example, for the elimination method of game background sound, this method calculates the estimated value of the echo signal through the echo feeder function, but this method requires multiple intermediate steps in the process of implementation, which is easy to introduce potential errors, and in the application field The above is mainly related to the processing of the game background sound, and the voice echo in the cloud video conferencing scene cannot be effectively eliminated, so it is not universal
