Abstract

The invention discloses a simple offline voice recognition method and system; a front word and a rear word jointly form a complete voice control command, the front word is located at the front part ofthe rear word, the front word is contained in a preset front word model library, and the rear word is contained in a preset rear word model library. The method comprises the steps: firstly, performing a front word sampling process; and performing model comparison of the front word on the voice sampling data of the front word and the data in the front word model library in real time, performing asampling process of the rear word after the comparison of the front word is passed, and performing model comparison of the rear word on the voice sampling data of the rear word and the data in the rear word model library in real time. According to the method and system, rapid, effective and accurate recognition is realized for offline voice-controlled electrical equipment, a special wake-up word is not needed, voice control is directly and simply realized, and the method and system have relatively high practicability and operability.

Description

technical field [0001] The invention relates to the application field of offline speech recognition, in particular to a simple offline speech recognition method and system. Background technique [0002] With the extensive application of offline speech recognition products, most products must use wake-up words, and frequent use of wake-up words makes it more difficult for users to use, and the user experience is poor. Therefore, it is necessary to find a solution that does not require a wake-up word but can be accurately identified. Contents of the invention [0003] The present invention realizes precise recognition on offline voice products by adopting the method of using prepositional words and postpositional words to jointly form a complete voice control command. [0004] Technical solution: a simple offline speech recognition method and system, including voice control commands, prepositional word model library, postpositional word model library, sampling of prepositio...
