Abstract

The embodiment of the invention discloses a voice recognition method and device, electronic equipment and a storage medium, wherein the method comprises the steps: obtaining subtitle text informationin a communication range when a current condition meets a lexicon selection condition, and extracting a keyword of the subtitle text information; determining a representation vector of the subtitle text information according to the word vector of the keyword, and selecting a target industry representation vector similar to the representation vector of the subtitle text information from preset industry representation vectors; and performing voice recognition on pulled audio data in the communication range based on an industry exclusive lexicon corresponding to the target industry representationvector. According to the method, the industry exclusive lexicon matched with the professional terms in the specific field can be selected for voice recognition in a communication scene containing theprofessional terms in the specific field, so that the voice recognition precision is improved, and the user experience is improved.

Description

technical field [0001] Embodiments of the present disclosure relate to the field of computer technology, and in particular, to a voice recognition method, system, device, electronic equipment, and storage medium. Background technique [0002] With the continuous development of the Internet and communication technologies, information communication through communication applications has become one of the important ways for users to exchange information. When communication between clients includes audio data, the server can transcribe the audio data into text through Automatic Speech Recognition (ASR) technology, and send the transcribed text to the corresponding client, so that the client can display the subtitles corresponding to the audio data. Existing ASR models usually use a general-purpose lexicon for speech recognition based on a general-purpose lexicon in a communication scenario that contains specialized terms in a specific field. The recognition accuracy is low and ...
