Abstract

The invention relates to the technical field of audio processing, and discloses a voice noise reduction method. The method comprises the following steps: acquiring voice data, inputting the voice data into a preset standard scene recognition model, and determining a voice scene corresponding to the voice data, the standard scene recognition model being obtained by training according to a noise sample set in each scene, and selecting a preset noise reduction model corresponding to the voice scene, and performing noise reduction on the voice data. In addition, the invention also discloses a voice noise reduction method and device, equipment and a storage medium. According to the invention, the accuracy of voice noise reduction can be improved.

Description

technical field [0001] The present application relates to the technical field of audio processing, and in particular to a voice noise reduction method, device and storage medium. Background technique [0002] Today's life is full of various noise audio data, such as noise audio data on the side of the road, noise audio data in the park, and noise audio data in the office. The audio characteristics of the noise audio data are different in different voice scenarios. At the same time, the corresponding voice noise reduction means are also different. [0003] The existing voice noise reduction method is based on the user's voiceprint feature, for example, the user's voice in the voice data is enhanced according to the user's voiceprint feature, so as to weaken the background noise and complete the voice noise reduction. However, in a practical application scenario, when the volume of the background noise is too large, this method cannot weaken the background noise based on the ...
