Abstract
Comparatively macroscopic phonemic units consisting of continuous sounds are used as standard patterns in continuous dynamic programming. In matching intervals between these standard patterns and input patterns, a sampled pattern is labeled according to the phonemes and phonemic particles which form the standard patterns. In the matching intervals, the labeled pattern is called a matching history. The matching history of a standard pattern when the continuous dynamic programming value is below a certain threshold value is used to recognize the phonemes of the input patterns.
