Problems solved by technology

Especially in some professional applications, external noise is unavoidable, and in many cases, the types of noise are complex and the intensity is large
This type of noise will have a serious impact on subsequent speech signal processing, such as reducing the accuracy of speech recognition
In addition, if the voice data containing noise is processed artificially, long-term work will cause damage to the human auditory system

Abstract

The invention relates to a voice denoising method based on computational auditory scene analysis and countermeasure network model generation. The method comprises the following steps: S1, processing noise-containing noises based on a generator generating a countermeasure network and a discriminator, thus obtaining an intermediate result; and S2, processing the intermediate result based on the computational auditory scene analysis method, thus obtaining a final result. With the method provided by the invention, part of noises in the voice signals obtained under the complicated channel background environment can be removed, and that no distortion occurs on the voice part can be well kept.

Description

technical field [0001] The invention relates to a speech noise reduction method, in particular to a speech noise reduction method based on computational auditory scene analysis and generation of an adversarial network model. Background technique [0002] Speech is the most important means for human beings to transmit information to each other. A piece of speech carries rich information such as the speaker's intention, identity, and emotion. Voice signals can be transmitted through various media such as air, water, and radio. Speech signals are usually interfered by various noises during the propagation process or due to the limitation of acquisition equipment. Especially in some professional applications, external noise is unavoidable, and in many cases, the types of noise are complex and the intensity is relatively large. This type of noise will seriously affect subsequent speech signal processing, such as reducing the accuracy of speech recognition. In addition, if the ...
