Outline of Research at the Start

本研究は、アジア・アフリカなどの新興英語圏の英語の特性を調査し、日本語母語話者が新興英語圏の英語をどの程度理解できるかを検証するものである。その上で、音声学、言語習得の面から、①なぜ第二言語では学習したモデルの発音から逸脱した方言への対応が困難か、②第一言語から第二言語への音声理解へのストラテジーを考察し、③第二言語音声習得が方言習得とどうかかわるのかを検証し、方言音声を含む第二言語音声理解のメカニズムを包括的に研究するものである。

Outline of Annual Research Achievements

2024年度は、前年度に録音したインド英語(第一言語ヒンディー語)、シンガポール英語(第一言語北京語、)バングラディシュ英語(第一言語ベンガル語)と、香港英語(第一言語、広東語・北京語)の分節音と韻律の音声特徴の分析を行った。
文節音の特徴は、/k, g/の二重調音化や、各地域の英語独特のものもあるが、地理的には広域にわたり、また元になっている話者の第一言語の音声・音韻特性は必ずしも一様でないにもかかわらず、共通の特徴も数多くみられる。例えば、二重母音の短母音化、無声・有声歯間音”th”を隣接する[t, d]など破裂音で代用する、/t, d/は反り舌音や気息を強く伴う/t, d/で代用する、摩擦音”s”, “sh”, “z”, “ju” などの調音位置が隣接する調音位置への変化、無声破裂音に続く母音の声帯振動開始時間の違いによる無声音・有声音の境界の変化、/l/-/r/の混同及び、/r/による/l/の代用、異なる調音の/l/や/r/の使用、母音と子音の脱落と挿入など、様々な特徴がみられた。
韻律上の特徴としては、強勢位置の変化、音節を単位とする発話リズム、母音や子音の脱落や挿入や異なる音素配列規則による音節構造の変化、母音の弱化の欠如、イントネーションの変化、トーンを強勢の代わりに代用する等がみられた。
これらの地域方言のうち、単語や音節の様々な位置で分節音の省略が起きる香港英語の発話サンプルが数多く取れたので、それらを使った刺激音を既に作成済みである。
また、日本語母語話者の分節音の長さと発話リズムに対する知覚と長さへの反応を検証するために、母音・子音とも分節音の長さを三段階で区別するエストニア語の録音を行い、知覚実験を行う準備を整えている。

Current Status of Research Progress
Current Status of Research Progress

3: Progress in research has been slightly delayed.

Reason

2024年度は、これまで収録した香港、シンガポールの英語を中心に、それぞれの英語の特徴ある文節音を含む単語を使った刺激音を作成した。その他の英語方言は、サンプル数が少ないため、日本で話者が見つかるたびに、追加録音を随時行っている。録音は全て、同じテスト語と無意味のフレーズ、テキストを使って録音をしているため、各方言の特徴が顕著に出ている単語と、無意味フレーズに出てくる対象語の理解度、発音の正確さの知覚実験を行う予定である。
インド英語とナイジェリア英語話者は、話者の第一言語により、英語の分節音の発音が著しく異なる例が少なからずあるため、同じ第一言語話者のサンプル数を増やすか、異なる第一言語話者の英語をもう少し集めるか、現在最終調整を行っている。
アジア・アフリカの英語の理解度等の判定と比べるために、一般の日本語母語話者が普段接することが多い、アメリカ英語やイギリス英語を対象とした実験も行う必要があり、そのための音声収録も行っている。標準アメリカ英語と標準イギリス英語話者男女数名ずつの発話データを録音し、知覚実験用のプラットフォームを作成している。

Strategy for Future Research Activity

2025年度は、アジアとアフリカの英語の知覚実験を行う予定である。対象とする被験者は、日本語を母語とする英語レベルが中級程度の一般の大学生・大学院生と、通訳などの仕事をしている日本人母語話者、またはある程度長期間英語圏在住歴のある大学生・大学院生等、英語レベルの高い日本語話者を対象とする。
知覚実験の調査項目としては、録音されたテスト語、フレーズを使い、内容の理解度、発音の明瞭性、外国語訛度、母語話者度の評価を行い、テキストの音読と自由会話をつかって、話者及び発音の印象の判断を行う。
一般の英語話者は小・中・高で主に標準アメリカ英語をモデル発音として英語教育を受けている場合が多く、また通訳などの英語を専門とする職業についている人たちも、アメリカ英語やイギリス英語を使った訓練を受けている人が多い。海外在住が長い日本語話者も、アメリカ英語やイギリス英語が主体のインターナショナルスクールで教育を受けた人が多いため、アクセントの比較の対象として、標準アメリカ英語を元にした実験も並行して行う予定である。
英語が中級レベルの日本語話者と英語上級者が、あまりなじみのない訛の英語をどの程度理解できるかと、英語上級者が難解と感じる発音、またアジア・アフリカの英語の音声特性のなかで、日本語訛に近い音声特性がどう理解されているか、されていないのか、その原因はなにか、またなじみのない訛の英語に対する印象の要因についての分析を行う。
合わせて、日本語母語話者の発話リズムに対する反応の検証として、母音と子音の継続時間を三通りに区別するエストニア語の解析も併せて進める。
