Abstract

The invention provides a voice recognition method and system, electronic equipment and a storage medium, and the method comprises the steps: obtaining training sample sets of different scenes, and enabling the training sample sets to comprise a plurality of training voices and text labels corresponding to the training voices; training a preset machine learning model according to the training sample sets of the different scenes to obtain semantic models corresponding to the different scenes; to-be-recognized voice is obtained, wherein the to-be-recognized voice carries a scene label; obtainingsemantic models corresponding to the scene labels from the semantic models corresponding to the different scenes; processing the to-be-recognized voice by utilizing the target semantic model to obtainan initial recognition result of the to-be-recognized voice; and performing calibration processing on the initial recognition result by using a preset language model to obtain a target recognition result of the to-be-recognized voice. According to the invention, the problems that targeted voice recognition cannot be carried out for a specific service scene of a user and the recognition accuracy is not high can be solved.

Description

technical field [0001] The invention relates to the technical field of voice recognition, in particular to a voice recognition method, system, electronic equipment and storage medium. Background technique [0002] At present, with the business development needs of various companies, there are more and more application scenarios for speech recognition technology, especially in the field of call centers, such as intelligent voice customer service, customer service recording quality inspection, and outbound call failure analysis. application. In different application scenarios, words with the same pronunciation may have different meanings. [0003] Traditional speech recognition technology generally relies on various complex model designs, including acoustic models and hidden Markov models (HMM). These models need to be built by specialized companies for enterprise users. Not only are the construction costs high, and special voice formats are limited, but most importantly, th...
