Abstract

The invention provides a voice recognition system and a voice recognition method used for individual equipment. The voice recognition method includes the steps of of: acquiring user voice input and recognizing the input voice on the basis of a limited grammar recognition network so as to acquire a first recognition result; in response to the first recognition result which does not satisfy the recognition acceptability condition, recognizing the voice input on the basis of a large vocabulary continuous voice recognition network to acquire a second recognition result; selecting a preferential result from the first recognition result and the second recognition result to be used as the final decoding result for the voice input. The embodiment of the invention provides a new voice recognition method and a new voice recognition device which are capable of supporting intelligent response to continuous voice inputs and quick response to a short voice command under uniform system interfaces.

Description

technical field [0001] The present invention generally relates to the field of voice signal processing, and particularly relates to a method and device for performing recognition on user voice input for mobile equipment. Background technique [0002] It has become an urgent need for the application and development of information technology to realize humanized and intelligent effective interaction between man and machine, and to build an efficient and natural human-machine communication environment. Especially in recent years, with the popularization of wireless communication networks, various intelligent portable mobile devices have played an increasingly important role in people's lives, and the increasing number of human-computer interactions requires a new and more intelligent device for small screen devices. For efficient and natural means of interaction. Voice, as the most natural and humanized means of interaction, is playing an increasingly important role. For exam...
