日本語学習者のカタカナ語の発音知覚率

Abstract

For this study, Koreans learning Japanese language were divided according their level to carry out perception rate tests on katakana pronunciation to examine the differences in perception rate in dictation test as proposed in my earlier study (2014) and the perception rate for each competence and mora (拍数). Also, factors affecting each perception rate were analyzed to contribute to education of katakana. The results of multilateral analysis and examination of the perception rate of katakana pronunciation can be summarized as follows: First, the perception rate for dictation of katakana was average 64.4% and the perception rate for the pronunciation as surveyed in this study was unexpectedly low with 53.3%. Second, similar to the results of dictation test, the lower the competence in Japanese language was, the lower the perception rate was; and the longer the mora was, the lower the perception rate was. Third, factors affecting perception rate for pronunciation include the problem of the sense of the special mora, especially the difficulty of pronouncing 「hikuon」, the phenomenon of 「sokuon」 insertion as well as the phenomenon of 「sokuon」 falling off, the difficulty of voiceless sound phenomenon of vowels, the interference of the mother tongue, the length of mora, and the problem of perceiving syllables such as 「ティ・ファ・フォ」 As discussed above, in order to reduce factors hindering perception rate in instructing katakana, the sense of the special mora should be first mastered sufficiently so that the learners reach confidence in the letters/characters and pronunciation of those words of short mora, and then the learners would be able to learn slowly the words of longer mora and words that include syllables such as 「ティ・ファフォ」
