Abstract

The invention relates to an echo cancellation method and device, a storage medium and computer equipment. The echo cancellation method comprises the steps: locally collected audio signals are obtained; a low-frequency signal and a high-frequency signal are extracted from the obtained audio signals; a far-end reference signal collected from the far end is obtained; according to the far-end reference signal, the low-frequency signal is subjected to echo suppression treatment, and a residual signal is obtained; the residual signal and the high-frequency signal are combined into a high-frequency residual signal; and according to the far-end reference signal, the high-frequency residual signal is subjected to residual echo suppression treatment, and an audio signal subjected to echo cancellation is obtained. According to the echo cancellation method and device, the storage medium and the computer equipment, when the audio signals are subjected to echo cancellation, the echo cancellation efficiency can be improved.

Description

technical field [0001] The present application relates to the technical field of speech signal processing, in particular to an echo cancellation method, device, storage medium and computer equipment. Background technique [0002] With the continuous development of voice signal processing technology and communication technology, users have higher and higher requirements for the quality of voice communication, such as using mobile phones to communicate with remote users, or players to communicate with team members when playing team games During the process, if there is no echo cancellation, it will seriously affect the effect of voice communication. [0003] The principle of echo generation: the remote audio signal is first played through the local speaker, then reflected in the room for many times, and finally collected by the local microphone together with the local sound. If the local end does not perform echo cancellation processing, the far end will play the remote audio...
