Outline of Final Research Achievements |
To refine the method of the acoustical measurement for the durational structure of rhythm units in English speech so that any type of English speech can be handled, multi-faced analyses regarding the phoneme composition of a rhythm unit, the position of a rhythm unit in a sentence, and an existence of a semantic emphasis for a rhythm unit were conducted, in addition, subdivided rules to increase the accuracy of the measurement were constructed. Moreover, as its application to education, to confirm that the difference between learner speech and native speech calculated by the refined measurement method of the rhythm unit can more accurately display the rhythm defect of the learner speech, its relationship with the subjective evaluation score showing the learner proficiency of the rhythm given by English language teachers was analyzed.

Academic Significance and Societal Importance of the Research Achievements |
まず,従来英語教育の現場で教師の経験に基づいて主観的に扱われてきたリズムの指導や評価に対して,客観的で定量的な情報を提供できる。この効果は,英語教育学や音声科学等の分野に貢献する。また,英語音声のリズムの時間構造が,精密な音響分析によって韻律的特徴に基づいて定量的に明らかとなる。この結果は,英語音声学のみならず諸言語のリズムを扱う韻律学の分野に寄与する。さらに,本研究の研究手法は,英語以外の言語に拡張することも可能であるため,本研究は,今後の多様な音声言語の評価や学習に対応し得る研究であるといえる。
