Abstract

The embodiment of the invention provides an audio noise reduction method and device and a computer readable storage medium, and relates to the technical field of voice processing. The method comprises the following steps: acquiring current audio data at a current moment and a preset scene label from an audio stream; performing voice recognition on the current audio data, and determining a first voice category of the current audio data; based on the first voice category and the scene label, generating a target noise reduction parameter for the current audio data; and performing noise reduction processing on the audio stream based on the target noise reduction parameter. According to the embodiment of the invention, the voice recognition is carried out on the current audio data, and the scene label is combined to match the corresponding target noise reduction parameter, so that the technical effect of improving the tone quality is achieved.

Description

technical field [0001] The present application relates to the technical field of speech processing, and in particular, to an audio noise reduction method, an apparatus, and a computer-readable storage medium. Background technique [0002] In the digital age of the Internet, after the sound is recorded, whether it is speech, singing, musical instruments, or even noise can be processed by digital music software, and people often need to do further noise reduction processing on audio files in order to pursue excellent sound quality. Disturbance of the audience by outside noise. [0003] In the prior art, fixed noise reduction parameters are generally configured on the server side. For example, in a live webcast scenario, in order to improve the voice quality of the anchor, a noise reduction function will be added during the recording process to eliminate the background noise brought by the anchor's voice collection process. However, the fixed noise reduction parameters cannot...
