Speech enhancement processing method

Abstract

The invention discloses a speech enhancement processing method. The method comprises the steps that a training sample is formed based on speech data and noise data; the training sample is preprocessedto obtain a processed denoising sample; the denoising sample is divided into multiple batches of denoising samples, a WGAN model is trained by adopting each batch of the denoising sample until training of multiple batches of the denoising samples is completed, and a final WGAN-MBGD model is obtained; an enhanced speech signal is output by adopting the final WGAN-MBGD model. The speech enhancementprocessing method has the advantages that the unstable adversarial network gradient is generated, the rate of convergence is quicker, the small-batch calculation is applied, the calculated amount isalso reduced, spectral subtraction factors and spectral lower limit factors are introduced, and the residual noise is reduced by reducing the error among frequency spectrums.

Description

technical field [0001] The invention relates to the technical field of speech processing, in particular to a speech enhancement processing method. Background technique [0002] In recent years, with the rapid development of information, the human-computer interaction system based on speech recognition has become the mainstream of research, and more and more speech processing technologies have been applied to major systems. However, these devices are usually located in a relatively complex acoustic environment, such as the sound of whistles on the street, music, birds, wind, etc. The noisy background noise often significantly deteriorates the voice quality, making voice commands unacceptable. Accurate identification, the system cannot complete a certain function, which greatly reduces the user experience and other problems. Therefore, the study of speech enhancement is a topic of practical significance. [0003] The purpose of speech enhancement is mainly to remove complex ...
