Abstract

The present invention provides a voice noise reduction method and device, a server and a storage medium. The method comprises the steps of: obtaining voice signals synchronously collected by an acoustic microphone and a non-acoustic microphone; performing voice activity detection according to the voice signals collected by the non-acoustic microphone, and obtaining a voice activity detection result; and performing noise reduction of the voice signals collected by the acoustic microphone according to the voice activity detection result, and obtaining the voice signals after noise reduction. Theeffect of noise reduction is enhanced, and the quality of the voice signals is improved.

Description

technical field [0001] The present application relates to the technical field of digital signal processing, in particular to a speech noise reduction method, device, server and storage medium. Background technique [0002] With the rapid development of voice technology, it has been widely used in many fields in daily life and work, providing great convenience for people's life and work. [0003] However, in the application process of speech technology, the quality of speech signal will generally decrease due to the interference of factors such as noise, and the decline of speech signal quality will directly affect the application of speech signal (such as speech recognition, speech playback, etc.). Therefore, how to improve the quality of speech signals has become an urgent problem to be solved. Contents of the invention [0004] In order to solve the above technical problems, the embodiment of the present application provides a voice noise reduction method, device, serve...
