Abstract

The invention provides an audio signal processing method and device, equipment and a storage medium. The method comprises the following steps: acquiring an audio signal; determining a noise feature corresponding to the audio signal by using a pre-trained noise reduction model; processing the noise feature corresponding to the audio signal to obtain a voice feature corresponding to the audio signal; and processing the voice feature corresponding to the audio signal to obtain a denoised target audio signal corresponding to the audio signal. Audio signals are input into a pre-trained noise reduction model, the noise reduction model comprises a noise classifier and a voice noise reduction device, the noise classifier is used for determining noise features corresponding to the audio signals, and the voice noise reduction device is used for determining voice features corresponding to the audio signals according to the noise features corresponding to the audio signals. Therefore, the voice noise reducer can utilize the noise features to assist in voice noise reduction, the voice noise reducer is better guided to extract the voice features, and a better voice noise reduction effect is achieved.

Description

technical field [0001] The present disclosure relates to the field of information technology, and in particular to an audio signal processing method, device, equipment and storage medium. Background technique [0002] With the continuous development of technologies such as artificial intelligence, speech enhancement, speech recognition, and audio and video communication, the sound quality of audio signals is becoming more and more important. In order to improve the sound quality of the audio signal, noise reduction processing may be performed on the audio signal. [0003] However, the prior art cannot effectively eliminate the noise in the audio signal, resulting in an unsatisfactory noise reduction effect. Contents of the invention [0004] According to an aspect of the present disclosure, an audio signal processing method is provided, including: [0005] get the audio signal; [0006] Using a pre-trained noise reduction model to determine noise features corresponding ...
