Abstract

The invention discloses a voice noise reduction method and device, a computer readable storage medium and an electronic device. The method comprises the following steps of performing voice separationon voice data to be denoised to obtain first voice data and second voice data of the voice data, and determining a first probability function corresponding to the first voice data and a second probability function corresponding to the second voice data; determining target noise reduction data of the voice data through the first probability function and the second probability function; performing noise reduction processing on the voice data through the noise reduction data; obtaining target voice data. According to the method, the voice data subjected to noise reduction is separated into two branches, namely the first voice data and the second voice data, and the noise data separated from the two branches is utilized to reduce the noise of the voice data mixed with the noise, so a technicalproblem of low accuracy of voice noise reduction in the prior art is solved.

Description

technical field [0001] The invention relates to the field of speech processing, in particular to a speech noise reduction method and device, a computer-readable storage medium and an electronic device. Background technique [0002] Speech signal processing technology is a key technology in the field of human-computer interaction today, and speech noise reduction can enhance the input speech and obtain relatively pure audio, which plays an extremely important role in the back-end speech recognition and is the core of speech signal processing. key technologies. [0003] The current speech noise reduction method mainly adopts the noise reduction method in the open source tool WebRTC, that is, calculates the spectral flatness, log likelihood ratio (LRT) feature, and spectral difference feature for the input audio, and updates the speech / noise according to the feature The probability function of the probability function, the noise estimate is updated according to the probability...
