Abstract

The invention relates to the technical field of voice recognition, provides a voice recognition method and device and electronic equipment, which aim to solve the problem of relatively low voice recognition accuracy. The method comprises the following steps of acquiring a to-be-recognized voice, performing feature extraction on the to-be-recognized voice to obtain voice feature information, determining a target character sequence corresponding to the voice feature information according to the target acoustic model and the target language model, wherein the target language model comprises a first language model and a second language model, the first language model is obtained by performing language model training through a command word training text of a first scene, and the second languagemodel is obtained by performing language model training through a first text training set. In the voice recognition process, two language models are adopted, and the first language model is obtainedby performing language model training through the command word training text of the first scene, so that the recognition capability of the first language model for related command words in the first scene can be enhanced, and the voice recognition accuracy can be improved.

Description

technical field [0001] The present disclosure relates to the technical field of voice recognition, in particular to a voice recognition method, device and electronic equipment. Background technique [0002] Speech recognition technology, also known as Automatic Speech Recognition (ASR), is a technology for converting speech into text and is widely used. For example, it can be applied to household appliances and voice-controlled devices (such as mobile terminals, smart toys, TVs, computers, automobiles, stereos, elevators, etc.), and can also be used in fields such as emergency calls. Get the text through speech recognition, convert the text into readable commands, and perform corresponding operations according to the commands. For example, for the elevator use environment, it is aimed at recognizing the control voice spoken by people in the elevator as relevant instruction words, and then converting them into commands readable by the elevator control chip, and then controll...
