Detection and Identification of Plosive Sounds in Japanese Words

摘要

A system for detecting and identifying plosive sounds in Japanese words is presented. The fundamental measure employed here to detect candidates for plosive sounds is the cepstral distance between an odd pair of frames with their starting positions coincided. We may eliminate some candidates from a preliminary analysis based on short-term power, pole positions obtained by low-order analysis and relative disposition in the discrimination space. Phoneme identification or mutual discrimination among the detected candidates for plosive sounds is carried out by using a following-vowel dependent discrimination algorithm formerly developed by the authors.
