Abstract

The embodiment of the invention belongs to the field of artificial intelligence, and relates to a single-channel speech enhancement method, which comprises the steps of carrying out feature extraction on noisy speech to be enhanced to obtain speech spectrum features, inputting the speech spectrum features into a trained speech enhancement model, carrying out data deformation on the speech spectrum features through a data deformation layer to obtain deformation features, inputting the deformation features into a convolutional network layer to obtain a first voice feature and a second voice feature, inputting the first voice feature and the second voice feature into a circulating network layer to obtain a first enhancement feature and a second enhancement feature, splicing the first enhancement feature and the second enhancement feature through an output layer, and outputting voice enhancement data. The invention further provides a single-channel speech enhancement device, computer equipment and a storage medium. In addition, the invention also relates to a block chain technology, and the speech enhancement data can be stored in a block chain. According to the invention, real-time speech enhancement can be realized, and meanwhile, the speech enhancement effect can be improved.

Description

technical field [0001] The present application relates to the technical field of artificial intelligence, and in particular to a single-channel speech enhancement method, device, computer equipment and storage medium. Background technique [0002] Voice is the most frequently used communication method for people, and it is also efficient and convenient. After entering the information society, voice signal, as the carrier of language, is one of the most important means for people to transmit information. However, the voice signal will inevitably be interfered by various noises in the process of acquisition and transmission. When collecting voice signals, the speaker is often in a complex and changeable environment, and the acquired voice signal will be mixed with other sounds, such as the noise of cars on the street, the sound of whistles, the background music in shopping malls, and the noise of people And the TV sound at home, etc. During the transmission process, the voi...
