A Study on the Realization of Korean Digits Recognition System Using the Simplified DTW Method

간소화된 DTW방식을 이용한 한국어 숫자음 인식기 구현에 관한 연구

This paper describes the simplified DTW algorithm for real time korean digit recognition and construct the digit recognition system using that algorithm. The DTW algorithm which is used nowadays have problems on real time recognition because of its massive computation. But, simplified DTW algorithm, which is proposed in this paper, solved these problems. In the case of single syllable, we use the characteristic of uniform distribution of epansion and contraction on time ais, compare distance of input pattern and reference pattern using constrainedly restricted path. As a result, we can reduce a great deal of computation and achieved that the real time korean digit recognition system.
