<p><P>PROBLEM TO BE SOLVED: To suppress a decrease in recognition accuracy, in voice recognition using word co-occurrence information. <P>SOLUTION: A voice recognition device includes a word detection unit and an evaluation value calculation unit. The word detection unit detects, from voice data, a recognition object word and a co-occurrence word of the recognition object word. The evaluation value calculation unit calculates an evaluation value for the combination of the recognition object word and the co-occurrence word on the basis of a time interval between a first voice section where the recognition object word is detected and a second voice section where the co-occurrence word is detected. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
