Abstract(in English) | In speech recognition using Hidden Markov Models (HMM), time warping is realized by state transitions. In this case, we match incoming speech sequences using identical statics during the interval in which the HMM stays in the same state by way of a self-transition (self-transition interval). Therefore, HMM does not take into account local dynamics of speech in a self-transition interval. In this paper VLSP (Variable Length Segment Prototypes) is proposed as a basic statistical representation of 'local' speech dynamics. The effectiveness of using VSLP is confirmed through word spotting experiments where the proposed method improves the word detection accuracy by 10~20%. |
