Abstract

The invention provides a voice identification method and system. The voice identification method comprises the steps that A, a client terminal module sends an obtained user voice instruction to a server module; B, the server module identifies the voice instruction preliminarily by the utilization of an instruction template set and a named entity set, obtains a preliminary identification result, and sends the preliminary identification result to the client terminal module, wherein the preliminary identification result is an identification result containing unknown variable information; C, the client terminal module identifies unknown variables through the named entity information stored in the client terminal module so as to obtain an integral identification result of the voice instruction. By means of the mode, the computing resources of a server can be fully utilized, and voice identification accuracy is improved.

Description

【Technical field】 [0001] The invention relates to speech recognition technology, in particular to a speech recognition method and system. 【Background technique】 [0002] With the development of software and hardware technologies related to mobile terminals, mobile terminals are becoming more and more intelligent. Operating mobile terminals through voice commands is the development direction of mobile terminal technology. To realize the control of mobile terminals by voice commands, the core is to correctly identify the user's voice commands. Only by correctly identifying the user's voice commands , to trigger the mobile terminal to execute the corresponding action. In the prior art, there are usually two methods for voice recognition of mobile terminals: [0003] The first method is to build a voice recognition system in the mobile terminal, and when the user issues a voice command to the mobile terminal, the built-in system is used to recognize the voice command. This me...
