Abstract

The invention provides a voice recognition method and device, electronic equipment and a storage medium. The method comprises the steps of determining to-be-recognized voice; based on the first voice recognition model, performing acoustic state prediction on the spectrum features of the to-be-recognized voice to obtain a first acoustic state posterior probability of the to-be-recognized voice; based on a second voice recognition model, acoustic state prediction is carried out on the semantic features of the to-be-recognized voice, and a second acoustic state posterior probability of the to-be-recognized voice is obtained; and fusing the first acoustic state posterior probability and the second acoustic state posterior probability, and performing speech recognition decoding based on a fused posterior probability obtained by fusion to obtain a recognition text of the speech to be recognized. According to the speech recognition method and device, the electronic equipment and the storage medium provided by the invention, speech recognition can be accurately carried out in a domain scene.

Description

technical field [0001] The present invention relates to the technical field of speech recognition, and in particular, to a speech recognition method, device, electronic device and storage medium. Background technique [0002] With the rapid development of artificial intelligence technology, speech recognition technology has been widely used in education, entertainment, medical care, transportation and other fields. [0003] At present, speech recognition models are obtained by training a large amount of corpus data collected in general scenarios, and speech recognition is performed based on the speech recognition models. However, when the speech recognition model is applied to specific domain scenarios, the speech recognition accuracy is low. SUMMARY OF THE INVENTION [0004] The present invention provides a speech recognition method, device, electronic device and storage medium, which are used to solve the defect of low speech recognition accuracy in specific field scena...
