音声認識装置
Document Type and Number:
Japanese Patent JP4604377
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To make it unnecessary to input an entire voice input object again at the time of correction in the case of the voice input object having a hierarchical structure and to prevent degradation of the recognition rate. SOLUTION: A voice information holding part 41 holds voice information inputted from a voice input part 27. When a voice is inputted for correction, a comparison and discrimination part 42 compares current inputted voice information with preceding voice information held in the voice information holding part 41 to discriminate resembling parts between them. A dictionary control part 34 of a voice recognition part 30 uses also a recognition result stored in a preceding result storage part 33 to perform dictionary control of taking only a part corresponding to a correction part as a comparison object pattern candidate. For example, when 'Aichi Prefecture, Kariya City, Showa town' is erroneously recognized as 'Aichi Prefecture, Kariya City, Shoei town' and 'Showa town' is inputted with voice for correction, only the town name part (concretely, Showa town, Shoei town, or the like) following Aichi Prefecture, Kariya City is taken as the comparison object pattern candidate.
