Scientific journal,Background There is an increasing interest in cross-linguistic influences of the second language (L2) on the first (L1), but its communicative impact remains to be elucidated. This study investigates how L2 learners’ L1 pronunciation is perceived as foreign-accented and (in) comprehensible as a function of their L2 learning experience and proficiency levels. Methods Read speech of 154 L1 Japanese learners of L2 English in the J-AESOP corpus was examined, where approximately one-third of them had lived in English-speaking countries and the rest had never lived outside of Japan. Their L1 speech was rated by another group of native Japanese listeners for accentedness and comprehensibility (from October 25, 2022 to August 20, 2023), while their L2 speech was previously rated by native American English listeners for nativelikeness or proficiency. The speakers’ vowel acoustics were also examined. Results More proficient L2 speakers were perceived as more foreign-accented in their L1, but only if they had lived overseas; their length of residence abroad predicted the degree of perceived accentedness. In contrast, more proficient L2 speakers were consistently perceived as more comprehensible in the L1, regardless of prior overseas experience. Acoustic analyses indicated that perceived accentedness is associated with a clockwise chain shift of all vowel categories in the vowel space. It was also revealed that the dispersion, rather than compactness, of vowel production contributed to perceived comprehensibility, although the degree of L1 vowel dispersion did not predict L2 proficiency. Conclusions The overall results suggest two main conclusions. First, perceptible L1 foreign accent likely results from L1 disuse rather than L2 interference, thereby L1 pronunciation differs from native norms at a system-wide rather than category-specific level. Second, L2 learning has a positive influence on perceived L1 comprehensibility, rather than individuals with clearer and more comprehensible L1 speech being inherently better L2 learners.

2023年度は実験のための準備を進めた。本研究プロジェクトは先行する日本語の研究プロジェクト(2018年度~2023年度に実施)の研究成果との比較を行うことを念頭にしているため、日本語プロジェクトを英語に置きかえる上でどのような問題があるかの検討を行った。大学に在籍する米国からの留学生にヒアリングを行い、シナリオの内容を検討した。その結果、シナリオの大半が日本文化に特有の状況を設定しているため、そのまま英語に置きかえることはできないことが判明した。また謝罪が要求されるシナリオにおける言語表現の選定に関して考慮すべき要素をある程度特定することができた。2023年8月には米国においてパイロットとして謝罪の音声を収集したが、シナリオを提示してその申し訳なさに関する数値を得るまでには至らなかった。

学習者英語研究において、伝統的に文法や発音の正しさを判断してきたのは、イギリス、アメリカ等の英語の母語話者だった。しかし、 今世紀の英語非母語話者の飛躍的増加により、現在では英語母語話者よりも非母語話者間のコミュニケーションの機会が圧倒的に多い。これを受けて、英語教育においても「母語話者らしさ」よりも「聞きやすさ」や「理解しやすさ」が重視されるようになった。本研究では、英語レベルの異なる日本人学習者に、様々な母語の話者の学習者英語の評定を行ってもらい、その評定値に影響を与えている音声特性を明らかにすることにより、英語発音指導およびリスニング指導におけるレベル別重点指導項目を明らかにする

外国語訛には、文節音の調音の問題、発話リズム、イントネーション、発話速度などの韻律の問題等があり、話者が伝えようとする内容が正しく伝達されるのを妨げる可能性がある。これまで、外国語訛は対象言語の母語話者が判定することが普通であったが、英語では、母語話者数よりも非母語話者数の方が多いという世界英語、世界共通語としての英語という観点から、非母語話者同志による訛のある英語の評価が必要となってきた。
そこで本研究では、日本語訛の英語の文節音の外国語訛度、母語話者度、理解度について、アメリカ英語話者、日本語母語話者に加え、フランス語母語話者が、日本語訛度の程度が異なる文節音をどう知覚するか、バイリンガル合成の技術を使って日本語訛度を変化させた文節音を含む英単語を使い検証した。日本語母語話者の英語発話でエラーの多い([l, r, th, kh,θ, f, v])(tとkの後のhは気息の意味)が語頭に起きるCVC構造の英単語を用い、100%日本語訛から100%アメリカ英語訛まで訛度を変化させた合成音を用い、フランス人の日本語訛の英語の知覚を、アメリカ人、日本人英語上級者と初級者と比較と比較した。
フランス語話者は、日本人やアメリカ人と比較して、日本語のラ行子音の弾き音とアメリカ英語の後部歯茎接近音間の母語話者度と、無声唇歯摩擦音[f]と日本語の「フ」の無声両唇摩擦音の理解度に対する評価が、アメリカ人と日本人と比べて明らかに異なっていた。
フランス人英語学習者にとって、これら二組の日本語と英語の子音の変化は、通常聞きなれない音の変化があり、これが明瞭度に大きな違いを生じさせていると思われる。これら二組では、フランス人は、音素カテゴリの変化をより唐突に感じており、新しい文節音に対し、適切なカテゴリを割り当てることができないため、理解度が大きく下がることを示唆していると思われる。

2022年度はコロナ禍がようやく下火になり、大学内における実験を行うことができた。2021年度に引き続き、音響実験室の使用はあきらめ、実験の実施は教室を使用するために授業期間中はできず制約があった。前年度に収録した音声データを用いた知覚実験は、大学の学内アルバイトの制度を利用して実験参加者を募集し、50名を対象に2022年9月に実施した。このデータを分析し、国際語用論学会で発表するための研究要旨を執筆した。この要旨はPhonetic Encoding of Sincerity in Expressive Speech Acts: An Analysis of Japanese Apologies in Experimental SettingsというタイトルでLectureのカテゴリーで採択され、2023年7月にベルギーで発表する予定である。
上述の研究成果は実験参加者がシナリオに応じて音声を出すために、参加者が同種の作業に対して示す技能には幅広い変種があり、知覚実験ではそのこと自体が明らかになったが、現実の言語運用とは乖離している可能性が示唆された。これを受けて、2023年2月には演劇経験をもつ発話者5名を対象に謝罪や感謝を示す可能性が高い表現を見せ、こちらが示す様々な口調で発話してもらうという音声実験を行った。同3月にこのデータを使用した知覚実験を行った。この結果は、音声が聞き手が話し手が謝罪をしていると認識する上で大きな役割を果たしていることを示しており、当初の仮説を裏付けている。このデータは現在様々な角度から分析している。この研究成果も上述のものとは別個に2023年度に発表する予定である。

This study investigated the effect of Japanese English prosody (e.g. accent, rhythm) on listener comprehensibility. Although not many studies have been conducted on the relative influence of each prosodic factor, the results of the current investigation suggest stress accent and foot rhythm (basic rhythm in English) have the strongest effects on listener comprehensibility.
