Abstract
A pattern recognition device has a DP matching section. The DP matching section performs frequency expansion DP matching to a standard pattern and a characteristic pattern obtained from input voice waveform to obtain a DP score and DP path pattern. It is determined by means of a category identification neural network using the DP path pattern obtained from the DP matching section whether a category of the standard pattern and a category of the characteristic pattern are the same, and a determination result corresponding to the degree of identification is obtained. A normalized DP score, which is the DP score normalized for individual differences within a required range, is then obtained in a divider by compensating the DP score using the determination result.
