Abstract

The invention provides a voice enhancement method, device, equipment and storage medium. The method comprises the following steps: acquiring a first voice signal and a second voice signal; acquiring asignal-to-noise ratio of the first voice signal; determining fusion coefficients of filtered signals corresponding to the first voice signal and the second voice signal according to the signal-to-noise ratio of the first voice signal; performing voice fusion processing on the filtered signals corresponding to the first voice signal and the second voice signal according to the fusion coefficientsto obtain a voice enhanced signal. The self-adaptive adjustment of the fusion coefficients of voice signals of a non-air conduction voice sensor and an air conduction voice sensor according to an environmental noise is realized, thereby improving the signal quality after voice fusion and improving the effect of voice enhancement.

Description

technical field [0001] The present application relates to the technical field of speech processing, and in particular to a speech enhancement method, device, equipment and storage medium. Background technique [0002] Speech enhancement is an important part of speech signal processing. Through the enhancement of speech signals, the clarity, intelligibility and comfort of speech in noisy environments can be improved, thereby improving the human auditory perception effect. In a speech processing system, before processing various speech signals, it is often necessary to perform speech enhancement processing first, so as to reduce the impact of noise on the speech processing system. [0003] At present, the speech quality is generally improved by combining a non-air conduction speech sensor and an air conduction speech sensor. The voiced / unvoiced segment is determined according to the non-air-conducted voice sensor, and the determined voiced segment representation is applied to...
