| Research Abstract |
This research aims to analyze which phonological features of English pronounced by Japanese students, who majored in Education to be English teachers, are pronounced incorrectly and affect intelligibility. By using these results, we developed multimedia pedagogical materials to improve their English. Through being judged by the authors and being used with acoustic analysis, all the words and sentences pronounced by the Japanese students were transcribed into IPA symbols indicating the accuracy of their English. As for intelligibility, native English speakers evaluated how much the words and sentences were understandable. The following phonological features were pronounced incorrectly:(a) /l/ and /r/ distinction,b,(b) fricative substitutions, (c) weak pronunciation of fricatives, (d) no aspiration of plosives, (e) incorrect vowel length, (f) the wrong stress on words, phrases, (g) monotonous rhythm. Among these features, (a)(c)(d)(e)(f) would affect intelligibility.
