Abstract

Embodiments of the present invention provide a voice detection method, device, and electronic equipment. The method includes: acquiring audio information through the audio acquisition unit; acquiring user voice information from the audio information; acquiring voice information through the video acquisition unit Video information; acquire facial expression change information when the user utters a voice corresponding to the voice information from the video information; judge the voice information and the facial expression change information, and when the judgment result indicates that the When the voice information satisfies the first preset condition and the facial expression change information satisfies the second preset condition, acquire the time when the facial expression change information satisfies the second preset condition, and the time is a time period or moment; The time is used to determine the audio end point of the audio message at the end. By adopting the method, device and electronic equipment provided by the embodiments of the present invention, the accuracy rate of obtaining the end point of the voice can be improved.

Description

technical field [0001] The present invention relates to the technical field of voice recognition, more specifically, to a voice detection method, device and electronic equipment. Background technique [0002] With the development of electronic equipment, speech recognition is more and more widely applied to electronic equipment. Speech endpoint detection is a necessary link in speech recognition, and the speech endpoint includes the tail point speech endpoint. [0003] Although speech endpoint detection technology has achieved encouraging accuracy in a quiet environment, in practical applications, the accuracy of tail speech endpoint detection usually decreases significantly due to the introduction of noise. Contents of the invention [0004] In view of this, the present invention provides a voice detection method and electronic equipment to overcome the problem in the prior art that the accuracy of end-point voice endpoint detection is usually significantly reduced due t...
