Abstract
In this study, we examined mispronunciations of Japanese sokuon (geminate consonants) by Chinese-speaking learners of Japanese using the corpus named I-JAS, which is made by the National Institute for Japanese Language and Linguistics. Two patterns of mispronunciations of sokuon were observed: (1) dropping of sokuon (pikunikku < pikuniku) and (2) replacement of sokuon with long vowels or moraic nasals (basuketto < basukeeto, sandoitchi < sandoinchi). The information on the J-CAT test scores is given in I-JAS and the learners of the Pre-Advanced level also make such mispronunciations of sokuon. Therefore, we highlight the necessity of the careful instruction of sokuon.
