Problems solved by technology

However, for speech enhancement, the biggest problem is the distortion of the enhanced speech
Speech distortion will lose a lot of very important speech information, seriously affecting the perceived quality and intelligibility of the enhanced speech, and restricting the performance of speech enhancement

Abstract

The invention discloses a single-channel speech enhancement system based on speech spectrum compensation. The single-channel speech enhancement system comprises a pre-enhancement module, a speech spectrum compensation module and a joint training module, wherein the pre-enhancement module is used for removing a part of interference signals in a speech; the speech spectrum compensation module is connected with the pre-enhancement module and is used for acquiring a weight matrix of speech spectrum compensation and fusing a pre-enhanced speech spectrum and an originally input speech spectrum by using the weight matrix; and the joint training module is connected with the pre-enhancement module and the speech spectrum compensation module and is used for performing joint training and optimizing the pre-enhancement module and the speech spectrum compensation module. The single-channel speech enhancement system based on speech spectrum compensation has the advantages that enhanced speech can be kept to have high tone quality in a noisy background environment, and the speech is clear and understandable.

Description

technical field [0001] The invention relates to the technical field of ranging, in particular to a single-channel speech enhancement system based on spectral compensation. Background technique [0002] Speech is one of the main means for human to exchange information, and speech enhancement has always played an important role in speech signal processing. 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] Interference encountered in actual speech can be divided into the following categories: ①Periodic noise, such as electrical interference, interference caused by the rotating part of the engine, etc., such interference is manifested as some discrete narrow-frequency peaks; ②Impulse noise, such as some electrical interference Noise interference caused by sparks and discharges; ③Broadband noise, whic...
