Abstract

A speech recognizing apparatus designed to predicate a duration of a recognition unit to be subsequently recognized with the use of both of the duration of the recognition unit already recognized within an input speech and the duration of each recognition units learned and then to perform a matching with the use of the predicated duration so that it can be established as a recognition candidate only when the difference in duration of the recognition units within the input speech is realistic. The apparatus comprises a reference speech storage buffer for storing information of the reference speech for each recognition unit, a reference speech duration storage buffer for storing duration information of the reference speech, a duration predicator for predicating the duration of the input speech, a matching unit for performing a matching between the reference speech and the input speech for each recognition unit and outputting a recognition result and an input speech duration storage buffer for storing duration information of the recognition result.
