Abstract

The invention provides a speech enhancement method, a speech enhancement device, a speech enhancement apparatus and a storage medium. The method includes the following steps that: the speech featuresof speech to be enhanced are obtained; the speech features of the speech to be enhanced are inputted into an enhancement model, so that the ideal ratio film (IRM) of the speech to be enhanced is obtained, wherein the enhancement model is a model which is implemented based on a generative adversarial network (GAN) and is used for obtaining the IRM according to the speech features; and the speech enhancement result of the speech to be enhanced is obtained according to the speech features of the speech to be enhanced and the IRM of the speech to be enhanced. With the speech enhancement method, the speech enhancement device, the speech enhancement apparatus and the storage medium of the invention adopted, a speech enhancement effect can be improved.

Description

technical field [0001] The present invention relates to the field of speech, in particular to a speech enhancement method, device, equipment and storage medium. Background technique [0002] Speech enhancement refers to the technology of extracting useful speech signals from the noise background to suppress and reduce noise interference when the speech signal is interfered or even submerged by various noises. [0003] In the prior art, speech enhancement based on deep learning is mainly realized through deep neural network (Deep Neural Networks, DNN), convolutional neural network (Convolutional Neural Network, CNN) or recurrent neural network (Recurrent neural Network, RNN). Also, DNNs, CNNs, and RNNs mainly model noise with known distributions. [0004] However, since the distribution of speech noise is usually complex and unknown, implementing speech enhancement based on deep learning through DNN, CNN or RNN has the problem of poor speech enhancement effect.
