Training method of noise reduction model, speech noise reduction method, device and electronic equipment

Abstract

The present disclosure provides a method for training a noise reduction model, a speech noise reduction method, an apparatus and an electronic device. The method comprises: obtaining source noisy speech data, and performing reverberation processing on the source noisy speech data to generate corresponding training samples, wherein the training samples comprise a plurality of samples, and each sample comprises multi-channel reverberation noisy speech data; training a to-be-trained speech noise reduction model based on the multi-channel reverberation noisy speech data included in the training samples to obtain a trained first speech noise reduction model. In the present disclosure, the human ear has a good listening experience for the noise reduction speech output by the trained speech noise reduction model, improves the propagation accuracy of the information carried in the speech data, reduces the influence of noise on the propagation of the information carried in the speech data, improves the robustness of the speech noise reduction model, strengthens the applicability and practicality of the speech noise reduction model, and optimizes the training method and training effect of the speech noise reduction model.
