METHOD AND SYSTEM FOR SPEECH RECOGNITION BY COMMON VIRTUAL PICTURE AND STORAGE MEDIUM STORED WITH SPEECH RECOGNITION PROGRAM BY COMMON VIRTUAL PICTURE

摘要

PROBLEM TO BE SOLVED: To enable efficient vocal transmission of an intension to an object in a common virtual picture by allowing a grammar management server to distribute difference information of grammar needed for speech recognition to a user terminal. SOLUTION: The system has a grammar management server which manages the grammar having a recognition object vocabulary registered in a text, etc., and a speech recognition result distribution server which distributes a speech recognition result. When a user terminal requests the grammar management server to update the difference information of the grammar needed for speech recognition (S1), the grammar management server distributes necessary difference information of the grammar to the user terminal at the start of the speech recognition (S2). The user terminal updates the grammar according to the distributed difference information (S3), recognizes an input voice by using the updated grammar (S4), and extracts (S5) and distributes (S6) the most likelihood vocabulary in the vocabulary in the recognition result to the distribution server. The distribution server distributes it to other user terminals (S7).
