Abstract

The invention discloses a voice recognition method, the method comprising: receiving a first voice input; performing coarse voice recognition on the received first voice input to obtain a first recognition result; receiving a second voice input; The second voice input is subjected to voice rough recognition to obtain a second recognition result; according to the first recognition result, a search is performed in the suggested complement lexicon to obtain a suggested complement; Whether the whole word matches; if it matches, confirm the suggested completion word as the fourth recognition result, increase the association weight of the suggested completion word in the suggested completion word lexicon, and output the fourth recognition result. The present invention can more quickly and accurately realize subsequent input voice recognition; it can flexibly update and suggest to complete the content of the thesaurus according to the user's language habits and usage habits to realize the dynamic update of semantic recognition and meet the personalized needs of users.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of speech recognition, and in particular to a method, device and system for speech recognition. Background technique [0002] Speech recognition technology is widely used in all aspects of the field of artificial intelligence. Artificial intelligence products such as smart home, assisted driving, and robots are inseparable from speech recognition technology. At present, although users can control artificial intelligence products through voice commands, there are still many limitations in the interaction between users and artificial intelligence products, and the content is relatively simple, which cannot yet reach or approach the communication mode between people. For example, the current speech recognition technology still has the defects of long speech input response time and low recognition accuracy. This requires an urgent solution to optimize the response time of voice input and i...
