Outline of Final Research Achievements

The research results so far are fragmentary, and the whole mechanism of perception and generation by North East Asian language learners could not be proved. This study was able to show how well the East Asian language learners (Mandarin, Shanghainese, Korean, and Japanese)perceived the category of Japanese plosives, the differences between dialect users, and the differences between first language users and second language learners. As a result of the study, significant differences in category perception were shown at the initial sound position in the order Mandarin> Shanghai> Korean, and sound position within words as Korean> Shanghai> Mandarin. The glottal opening pattern of the first language users is /p/ > / b/, where /p/ is almost the same as the non-aspirate （Korean）and the unvoiced and non-aspirate（Mandarin, Shanghai）plosive. / b/ was smaller than in any dialect of any language.
