Outline of Final Research Achievements

In this research project, (i) and (ii) were conducted: (i) a study of native English speakers' production and prosodic prominence ratings of English full vowels in a marked environment which is adjacent to the primary-stress syllables within the same words, and (ii) a study of English lexical stress location judgments by Japanese and Korean learners of English. As for (i), although no results were obtained to support the full vowels in the marked environment being rated as 'weak', the results of the production experiment suggested a possibility that lax full vowels in that environment may be reduced to the extent that their formant properties were deviated from the properties of full vowels in other environments. The study of (ii) suggests that when the learners’ native language has a lexical accent system, they make their English stress location judgments based on the unmarked lexical accent pattern of their native language.

Academic Significance and Societal Importance of the Research Achievements

英語は語強勢言語であり、語強勢の有無と母音の質との間に密接な関係がある。原則、強音節は完全母音を核とするのに対し、それに隣接する音節は弱音節であり母音の質も弱化する。しかし中にはその環境においても弱化せずほぼ完全母音と同じ音質を保つ母音も存在する。そのような母音の正体を明らかにすることが本課題の研究①の目的であったが、この①で得られた結果は日本における英語母音の発音教育に直接生かせる知見であると考える。研究②では、日本人英語学習者が英単語のどこに語強勢を付与する傾向が高いかを解明することを試みたが、この研究で得られた知見は日本人英語学習者への英語語強勢の指導に直接生かせる知見である。
