Title:
VOICE RECOGNIZING DEVICE
Document Type and Number:
Japanese Patent JP3171107
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To enable the recognition utilizing continuation time of syllable by correcting a vice, which is as candidate of recognition result, on the basis of the mean syllable length and the continuation time length of each syllable of the voice to be recognized.
SOLUTION: An input voice is also input to a syllable boundary detecting unit 104, and the syllable detecting unit 104 obtains a position of candidate of a syllable boundary on the basis of the power information or the like, and outputs it to a mean syllable length estimating unit 105. The mean syllable length estimating unit 105 utilizes a characteristic that the continuation time length of each syllable is nearly constant so as to estimate the mean syllable length of the input voice on the basis of the information on each syllable boundary candidate. A candidate selecting unit 106 checks whether the continuation time length of each syllable exists between the minimum continuation time and the maximum continuation time length, which are decided on the basis of the mean syllable length obtained by the mean syllable length estimating unit 105, or not for each candidate, which are output from a voice recognizing unit 101, and in the case where any one sound, of which continuation time is out of the range, exists, this candidate is discarded, and in the case where a candidate, of which all syllables having continuation time in the range, is found, this candidate is recognized.
