| Abstract(in English) | Speaker dependent voice recognition performance was achieved with template matching (TM). In order to give a margin to TM, sums of absolute value of wavelet transform coefficients in each scale (SWLC's) are used for vector quantization. Japanese moras are recognized under the condition of 204.8msec (1024 pieces of data those are sampled every 0.2msec) as a unit of processing. As for a segmentation, the ratio of SWLC (the 0.8msec band)/SWLC (the 1.6msec band) and SWLC (the 1.6msec band)/SWLC (the 3.2msec band) become a node in t he transition region of vowel [a,i,u,e,o]. Vowels uttered the same speaker were recognized by TM with 15 piece of WLC's in low resolution (scale is over 0.8msec) where the segmentation of processing is shorter then the pitch in order to make adaptable to the valid speech sound. Here, the data were sampled at each 0,1mces and 64 pieces of data were picked up from each peak of voice and the set of data are transferred to Haar's discrete wavelet coefficients (WLC's). |
