Training method of audio signal noise reduction model, audio signal noise reduction method and equipment

Abstract

The invention is suitable for the technical field of communication, and provides a training method of an audio signal noise reduction model, an audio signal noise reduction method and equipment, and the audio signal noise reduction method comprises the steps: converting a currently collected audio signal with noise into an audio vector with noise; and inputting the audio vector with noise into a trained audio signal noise reduction model for noise reduction processing to obtain a noise-reduced audio signal. According to the method, the audio signal noise reduction model directly extracts the feature information used for distinguishing the audio signal and the noise signal based on the noise frequency vector corresponding to the noise frequency signal, and performs noise reduction processing based on the extracted feature information, so that the audio signal and the noise signal corresponding to the noise frequency vector can be accurately separated; the noise reduction effect of the audio signal with noise is improved, the audio quality is improved, and the voice call quality is further improved.

Description

technical field [0001] The present application belongs to the technical field of communication, and in particular relates to a training method for an audio signal noise reduction model, an audio signal noise reduction method and equipment. Background technique [0002] The audio signal collected by the terminal device usually contains noise, and when the audio signal is further processed, it is usually required to perform speech noise reduction. Speech noise reduction is an effective processing technology for noise problems. Its purpose is to eliminate the influence of noise, improve speech clarity, and improve speech quality. [0003] For example, during a voice call, the audio signal collected by the terminal may contain environmental noise, other people's voices, etc. Before encoding and transmitting the audio signal, the terminal usually needs to perform voice noise reduction processing on the audio signal to obtain pure voice. Signal. The pure speech signal refers to ...

AI Technical Summary

Problems solved by technology

[0005] In view of this, the embodiment of the present application provides a training method of an audio signal denoising model, an audio signal denoising method and equipment, so as to solve the problem that the existing denoising method cannot accurately separate the noise signal, and through the existing denoising method There is still a lot of noise in the audio signal obtained after the noise reduction processing, and the pure voice signal cannot be obtained, and the noise reduction effect is not good.
