Abstract

The present disclosure provides an audio signal processing method, device, device, and storage medium. The method includes: acquiring an audio signal; using a pre-trained noise reduction model to determine the noise characteristics corresponding to the audio signal; The feature is processed to obtain the speech feature corresponding to the audio signal; the speech feature corresponding to the audio signal is processed to obtain a noise-reduced target audio signal corresponding to the audio signal. By inputting the audio signal into the pre-trained noise reduction model, since the noise reduction model includes a noise classifier and a speech denoiser, the noise classifier is used to determine the noise characteristics corresponding to the audio signal, and the speech denoiser is used to The corresponding noise feature determines the speech feature corresponding to the audio signal, so that the speech denoiser can use the noise feature to assist in speech noise reduction, and better guide the speech denoiser to extract speech features, thereby achieving a better speech noise reduction effect .

Description

Technical field [0001] The present disclosure relates to the field of information technology, and more particularly to an audio signal processing method, apparatus, device, and storage medium. Background technique [0002] With the continuous development of artificial intelligence, voice enhancement, speech recognition and audio and video communications, the sound quality of the audio signal is increasingly important. In order to improve the sound quality of the audio signal, the audio signal can be performed. [0003] However, the prior art cannot effectively eliminate noise in the audio signal, resulting in less expensive noise reduction effect. Inventive content [0004] According to an aspect of the present disclosure, an audio signal processing method includes: [0005] Get an audio signal; [0006] The noise feature corresponding to the audio signal is determined using a pre-trained noise reduction model; [0007] The noise feature corresponding to the audio signal is proc...
