Abstract

The invention discloses a voice recognition method and device, computer equipment and a storage medium, and the method comprises the steps: obtaining to-be-processed voice data; performing entity recognition on the to-be-processed voice data by adopting an entity recognition algorithm to obtain at least two original entity recognition corpora; performing entity identification filtering on each original entity identification corpus to obtain an identification entity and an entity probability; performing intention recognition on each original entity recognition corpus to obtain a recognition intention and an intention probability; obtaining an entity probability weight based on the entity probability and the intention probability corresponding to each original entity identification corpus; and extracting the maximum entity probability weight as a target probability weight, and obtaining a target identification result. According to the method, the entity recognition accuracy can be effectively improved, inaccurate entities recognized in the to-be-processed voice data are filtered out, and the overall interaction efficiency of intelligent voice interaction is improved.

Description

Technical field[0001]The present invention relates to the field of intelligent interaction technology, in particular to a voice recognition method, device, computer equipment and storage medium.Background technique[0002]The voice assistant is equivalent to the "personal assistant", that is, when the user has a need, he can directly make a voice call to the device deployed with the voice assistant, and the voice assistant will answer the user's needs and help the user solve the problem. NLP ((Natural Language Processing, natural voice processing) Processing) is an important development direction. The voice assistant algorithm includes two major steps: entity recognition and intent recognition, that is, entity recognition first, then intent recognition. Obviously, the result of intent recognition depends on the result of entity recognition. If entity recognition Wrong, the subsequent intent recognition results are likely to be inaccurate. Currently, there is no mechanism for judging w...
