Embodiment Construction

[0043] In order to make the purpose, technical solutions and advantages of the present invention clearer, the technical solutions in the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the present invention. Obviously, the described embodiments are part of the embodiments of the present invention , but not all examples. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0044] Speech enhancement is the technique of extracting pure original speech from noisy speech. Due to the existence of various noises around the environment, such as white noise generated by nature, sudden noise made by man-made, and reverberation generated by room reflection, etc., the voice signal received by the microphone is also mixed with noise, and then Affect the quality and intell...

Abstract

The invention provides a voice enhancement method and device, electronic equipment and a storage medium, and the method comprises the steps: obtaining collected original voice, carrying out the noise reduction of the original voice, and obtaining noise-reduced voice; determining a speech enhancement mask of the original speech based on the original speech and the noise reduction speech; and performing voice enhancement on the original voice based on a voice enhancement mask. According to the embodiment of the invention, the original voice information and the noise reduction voice information are fused into the voice enhancement mask, so the voice enhancement mask can accurately learn the mapping relation from the original voice with noise to the clean voice, and the voice enhancement effect is improved.

Description

technical field [0001] The invention relates to the technical field of speech signal processing, in particular to a speech enhancement method, device, electronic equipment and storage medium. Background technique [0002] Since the speech collected by the device is usually noisy speech, the main purpose of speech enhancement is to denoise the noisy speech, that is, through speech enhancement, various interference signals can be effectively suppressed and the target speech signal can be enhanced. [0003] At present, the voice enhancement network model is used to enhance the speech with noise, but training the speech enhancement network model requires a large number of speech or noise data samples, and sometimes these samples are difficult to obtain, which affects the noise reduction performance of the speech network model . Contents of the invention [0004] The invention provides a voice enhancement method, device, electronic equipment and storage medium, which are used ...
