Abstract

The invention discloses voice signal enhancement method, device and equipment. The method comprises the following steps of: acquiring a voice signal and geographical position information correspondingto the voice signal; and matching an environment scene type for a voice field corresponding to the voice signal according to the geographic position information, eliminating the environment noise inthe voice signal according to the environment scene type, identifying required voice data from the voice signal after the environment noise is eliminated, and enhancing the identified voice data. Through the above mode, the interference of the environmental noise contained in the voice signal can be reduced, the accuracy of voice recognition from the voice signal is improved, and the effect of voice enhancement of the recognized voice can be improved.

Description

technical field [0001] The present invention relates to the technical field of voice, in particular to a voice signal enhancement method, device and equipment. Background technique [0002] Speech enhancement refers to the technology of extracting useful speech signals from the background of environmental noise to suppress and reduce the interference of environmental noise when the speech signal is interfered or even submerged by various environmental noises. [0003] However, the existing speech signal enhancement schemes generally perform speech recognition on the speech signal, and use a noise reduction method to perform speech enhancement on the recognized speech, but because the speech signal contains environmental noise interference, the speech recognition will be inaccurate , resulting in poor speech enhancement. Contents of the invention [0004] In view of this, the object of the present invention is to propose a voice signal enhancement method and device and equ...
