Abstract
At the time of training reference speech, the relationship between durations of each recognition unit is obtained by a duration training circuit and, at the time of recognizing speech, a beginning and an end of input speech is detected by a speech period sensing circuit, and then by using the relationship and the input speech period length, the durations of the recognition units in the input speech are estimated. Next, the reference speech and the input speech are matched by the matching means by using the calculated estimation values in such a manner that the recognition units have a duration close to that of the estimated values.
