PROBLEM TO BE SOLVED: To improve voice recognizing performance on hardware composed of a CPU which has a small memory and small processing capability. SOLUTION: Temporary phoneme speech continuing times T11, T12... by phonemes constituting an input voice are obtained, the voice section of the input voice data is divided by the mentioned phoneme speech continuing times, and the path from the 1st-stage phoneme model to the final-stage phoneme model of HMM is given limitations on some phoneme model in sections (other than the sections shown by thick-line arrows) from certain time to certain time based upon the temporary phoneme speech continuing times. The limitations of the path is the control for inhibiting the transition from the final state of one phoneme model to the initial state of the next phoneme model from certain time to certain time based upon the temporary phoneme speech continuing times.
