<p>An pattern dissimilarity calculator according to the present invention, which calculates a pattern dissimilarity between a first and second sequence feature pattern using either the DP matching approach or the HMM (Hidden Marcov Model) approach, comprises cumulative distance calculator 1 for calculating the distance between frame i of said first sequence feature pattern and each of frames of said second sequence feature pattern, and obtaining a current cumulative distance by adding to an cumulative distance obtained in terms of frame i-1, which is decoded in cumulative decoder 4; and cumulative distance encoder 2 for encoding the cumulative distance calculated by the cumulative distance calculator 1. The cumulative distance decoder 4 decodes cumulative distances encoded by the encoding means. <IMAGE></p> |
