Embodiment Construction

[0041] The following will refer to Figures 2 to 8 A speech recognition system according to an embodiment of the present invention is described. Similar or corresponding parts in all drawings are denoted by similar or corresponding reference numerals, and descriptions will not be repeated below.

[0042] figure 2 The whole of the speech recognition system according to the first embodiment of the present invention is shown. Such as figure 2 As shown, the speech recognition system includes a client device 110 for receiving user speech, and a server device (additional speech recognition device) 120 that can communicate with the client device 110 through a communication network 130 . The illustrated client device 110 performs initial recognition on the user's voice, and generates a first-time recognition result of the user's voice. The server device 120 performs secondary recognition on the user's voice, generates a secondary recognition result of the user's voice, and outpu...

Abstract

A speech recognition system has: a recognition dictionary for storing speech information; a primary speech recognition device for performing primary speech recognition in response to input speech information sent by a user using the recognition dictionary; and a recognition result judging device for judging whether to accept or not Reject the initial speech recognition result. The voice recognition system includes: a transceiver device, used for sending the user's input voice information to an additional voice recognition device when the recognition result judging device rejects the initial voice recognition result, and receiving the voice information generated by the secondary voice recognition of the additional voice recognition device The secondary speech recognition result; and the recognition result output device, used to output the primary or secondary speech recognition result to the outside of the speech recognition system. The voice recognition system further includes: determination result input means for receiving determination information on the primary or secondary voice recognition result; and dictionary content control means for updating the recognition dictionary based on the determination information.

Description

technical field [0001] The present invention relates to a speech recognition system and method, more particularly, to a server-client speech recognition system and method. The present invention also relates to a computer-readable storage medium on which a program for voice recognition is recorded. The invention is applicable to voice input interfaces such as cellular telephones or personal digital assistants. [0002] This application claims priority from Japanese Patent Application JP 2005-217534, the disclosure of which is incorporated herein by reference. Background technique [0003] figure 1 is a schematic diagram showing an example of a conventional server-client speech recognition system having a client device and a server device. In a traditional server-client speech recognition system, a client device handles a relatively light-loaded speech recognition, while a server device handles a relatively heavy-loaded speech recognition. Specifically, such as figure 1 A...
