  • Audiovisual English /r/−/l/ Identification Training for Japanese-Speaking Adults and Children

    Yasuaki Shinohara

    Journal of Speech, Language, and Hearing Research   64 ( 7 ) 2529 - 2538  2021.07  [Refereed]

     View Summary

    <sec>
    <title>Purpose</title>
    This study tested the hypothesis that audiovisual training benefits children more than it does adults and that it improves Japanese-speaking children's English /r/−/l/ perception to a native-like level.


    </sec>
    <sec>
    <title>Method</title>
    Ten sessions of audiovisual English /r/−/l/ identification training were conducted for Japanese-speaking adults and children. Assessments were made of age effects on the increase in identification accuracy in three testing conditions (audiovisual, visual only, and audio only) and auditory discrimination of the primary acoustic cue (F3 frequency).


    </sec>
    <sec>
    <title>Results</title>
    The results showed that both adults and children increased their identification accuracy in the audiovisual condition more than in the single-modality conditions (visual only and audio only). Their improvement in the visual-only condition was larger than that in the audio-only condition. Japanese-speaking adults and children improved their primary acoustic cue (F3) sensitivity to a similar extent. In addition, their identification improvement in the audiovisual condition was positively correlated with those in the audio-only and visual-only conditions. The improvement in the audio-only condition was also positively correlated with that in the visual-only condition and with primary acoustic cue sensitivity.


    </sec>
    <sec>
    <title>Conclusion</title>
    It was unclear whether children had an advantage over adults in improving their identification accuracy, but both age groups improved their auditory and visual perception of the English /r/−/l/ contrast and showed additive effects in the multisensory (i.e., audiovisual) condition.

Specific Research

  • 音素認知と音声知覚の関連性調査

    2020  

     View Summary

     本研究課題では、事象関連電位(ERP)と呼ばれる脳活動の内、ミスマッチ陰性電位(MMN)という成分を分析することで、音声と音素に対する知覚能力を評価している。2019年度は、日本語話者による音素/t/-/d/に対する知覚を分析し、論文を執筆した。この論文は2020年に国際ジャーナル(Brain Research)から出版された。 その後、コロナウイルス感染拡大の状況に合わせて研究を中断した。再開後は日本語話者や広東語話者に対して、母音や子音の長さに係る知覚実験をオンラインで実施し、母語の音韻体系による知覚能力への影響を調査した。我々はその結果を国際学会論文にまとめ、提出した。

  • 第二言語音声知覚の言語間研究

    2019   Arild HESTVIK, Chao HAN

     View Summary

     本研究は、日本語話者が英語の音素を知覚する際、日本語音素の存在がその知覚にどのような影響を及ぼすか、行動実験と脳波計測実験の両面から調査した。研究代表者はPerceptual Assimilation Model (PAM; Best, 1994; 1995)を基に仮説を立て、まずは行動実験によりその仮説を検証した。その結果は、国際学会(ICPhS 2019, New Sounds 2019)で発表し、論文も出版した。同時に脳波計測実験も実施し、事象関連電位(ERP)と呼ばれる脳活動の内、ミスマッチ陰性電位(MMN)という成分を分析した。行動実験では仮説通りの結果が表れたが、MMNの分析では予測と異なる結果が表れた。本研究費を使用して、第二言語音声知覚の分野で著名な研究者を国内にお呼びし、研究結果に関してディスカッションを行った。

  • 言語間における母音知覚

    2018   Arild Hestvik

     View Summary

    3年間のプロジェクトである本研究課題は、第二言語音声知覚に関する理論を行動実験及び脳波計測の両面から検証することを目的としている。最終年度にあたる2018年度は、英語話者と日本語話者による母音の知覚能力を調査した。音響の統制された母音の刺激音に対する知覚能力が、第一言語の音韻体系の違いによってどのように異なるか、実験を行った。それらの研究成果は2019年度に開催予定の国際学会(ICPhS2019やNew Sounds2019)での発表を予定している(Accepted)。その他、子音に対する知覚能力の実験結果は、2018年6月に国際学会(MismatchNegativity 2018)で発表した。

  • 事象関連電位による第二言語音声知覚の評価

    2017   酒井弘

     View Summary

     本研究課題は3年間のプロジェクトであり、日本語話者と英語話者による音声知覚能力を行動的評価だけでなく、脳科学的アプローチによって比較分析することを目的としている。二年目にあたる2017年度には、主に子音/t/-/d/の知覚を対象した研究を行った。日本語話者を対象に、音声の変化を知覚した際に表れる脳波形の変化 (Mismatch Negativity; MMN)を計測し、先行研究で示された英語話者のものと比較した。我々は本研究成果を国際学会(Society for the Neurobiology of Language 2017)で発表し、また、国際ジャーナルへ投稿した。2018年3月現在、査読を待っている状態である(Under review)。

  • 日本語母語話者による英語音声知覚

    2016  

     View Summary

     本研究は、3年間のプロジェクトとして、日本語話者の英語音声に対する知覚能力を計測することで、母語と第二言語音声の知覚能力の違いや母語による音声知覚への影響を検証している。2016年度は、本プロジェクトの初年度として、主に二つの実験を行った。一つは、日本語に含まれない英語音声に対する知覚能力を測定し、視聴覚トレーニング効果を検証した。もう一つは、日本語と英語の両方に存在する音声に対する知覚能力を測定した。日本語話者がそれらの音声を聞いた際の脳反応も測定し、先行研究で得られた他言語話者のものと比較した。
