Abstract

The invention discloses a filtering method and apparatus for echo cancellation, a device and a medium. The method is iteratively executed multiple rounds and comprises, at least, the steps that the round of far-end audio data and near-end audio data is acquired; according to the round of self-adaptive echo cancellation parameters, response to the round of far-end audio data is estimated; accordingto the round of near-end audio data and the response, a filtering result of the round of near-end audio data is determined, wherein the round of self-adaptive echo cancellation parameters is obtainedaccording to precious at least one round of self-adaptive echo cancellation parameters and far-end audio data. The echoes produced by double parties and the multiple parties of the far end and the near end in voice communication can be more effectively cancelled through self-adaptive filtering, and accordingly ensuring of voice communication quality is facilitated.

Description

technical field [0001] The present application relates to the technical field of voice communication, and in particular to a filtering method, device, device, and medium for echo cancellation. Background technique [0002] Voice communication is a relatively common interaction scenario between users, for example, two users talk through a mobile phone, and multiple users conduct a remote conference through a teleconferencing terminal. In this type of voice communication scenario, for any user at one end, it is often necessary to both send voice to the other end and answer the voice from the other end to itself. The local end of any user can be called the near end. The opposite end can be called the remote end. [0003] The user generally uses the microphone provided by the mobile phone or the teleconferencing terminal to send voice to the other end, and through the earpiece or speaker provided by these devices, the user listens to the voice sent by the other end. However, w...
