DEVICE AND METHOD FOR RECOGNIZING VOICE AND RECORDING MEDIUM

摘要

PROBLEM TO BE SOLVED: To efficiently perform a processing while keeping high voice recognition performance. SOLUTION: A word preliminary selection part 13 selects preliminary words. A matching part 14 calculates the score of the selected words and constitute a word string to be the candidate of a voice recognizing result based on the score. A control part 11 generates word connecting relation between the words of the word string to be the candidate of the voice recognizing result, supplies it to a word connecting information storage part 16 and permits the part 16 to store it. A re-evaluating part 15 corrects word connecting relation stored in the storage part 16 one by one and the control part 11 establishes the word string to be the voice recognizing result based on word connecting relation after correction. In this case, a word connecting relation managing part 21 restricts a time to be taken in a word boundary as word connecting relation stored in the storage part 16 and a word connecting relation managing part 22 restricts the start time of the word for the word preliminary selection of the word preliminary selection part 113.
