Abstract

A training method for a speech enhancement network, a speech enhancement method, and an electronic device. The training method comprises: performing speech effectiveness classification on respective enhanced speech frames, and on the basis of the classification results of the enhanced speech frames, generating an effectiveness distribution for sample enhanced speech; by means of the effectiveness distribution, determining the speech classification accuracy of the speech enhancement network; and measuring the degree of change in speech effectiveness of each enhanced speech frame compared to that before noise reduction, and on this basis, determining speech enhancement accuracy according to noise reduction accuracy and the speech classification accuracy. In this way, the method can focus on improving the ability of the speech enhancement network to suppress noise in non-speech segments. When the trained speech enhancement network is used to perform noise reduction on speech to be processed, if the speech comprises non-speech segments, the trained speech enhancement network can effectively reduce the phenomenon of residual noise and improve the quality of speech enhancement. The invention can be widely applied in various scenarios such as cloud technology, artificial intelligence, smart transportation, and assisted driving.
