    　View Summary

    This study investigates the predictions of second language (L2) acquisition models — SLM, PAM-L2, and L2LP — on how native (L1) Japanese speakers implement the spectral and temporal aspects of L2 American English vowel categories. Data were obtained from 102 L1 Japanese speakers in the J-AESOP corpus, which also includes nativelikeness judgments by trained phoneticians. Spectrally, speakers judged to be less nativelike showed a strong influence of L1-L2 category assimilation, except L2 /æː/ whose dissimilarity from L1 categories likely triggered new category formation, in accordance with SLM and PAM-L2. However, more nativelike speakers showed vowel spectra similar to those of native English speakers for all vowels, which aligns better with L2LP. Temporally, although speakers tended to assimilate the phonetic length of English vowels to Japanese phonemic length distinctions, segment-level L1-L2 category similarity was not a significant predictor of the speakers’ nativelikeness. Instead, implementation of prosodic-level factors such as stress and phrase-final lengthening were better predictors. The results highlight the importance of suprasegmental factors in successful L2 category learning and also reveal a weakness in current models of L2 acquisition, which focus primarily on the segmental level. The use of speech corpora for L2 research is discussed.

  • 日本人学習者に対する英語リズム指導効果の縦断的検証

    2022  

    　View Summary

    本研究は日本人学習者の英語リズムの習得における明示的指導の効果を縦断的に検証するものである。英語音声のリズムは、ストレスアクセントとフットの等時性が影響しているが、日本人学習者は、習熟度とともに両者が母語話者のものに近付くことが先行研究により示されている。リズムの指導においては、聴覚刺激だけでなく視角刺激も音声知覚に影響を与えることが知られているため、マスク着用義務が緩和される2023年度当初に実験を行うこととし、2022年度内には指導時および成果検証 (事前、事後テスト) 時に学習者が読む文章を選定し、リズムの測定に適した形に改変するために適宜単語の挿入、削除、変更などを行った。この際、語彙習得を専門とする共同研究者の助言を得て、文章の語彙レベルも統制した。

    本研究では、英語の没入教育が行われている早稲田大学国際教養の1年生を対象に、入学直後である4月と、1月に同一音声の評定を行ってもらった。音声学者16名による評定 (相互の相関係数 > 0.9)の平均値と比較した結果、4月時点において英語の習熟度(TOEFL ITPのスコア)が高い学習者の方が総じて音声学者の評定との一致率が高かった一方、同一話者による4月時点と1月時点の評定値の一致率は極めて高く(およそ0.8)、音声学者の評定との一致度の縦断的変化も起こらなかった(相関係数最大0.5程度の変動)。この原因として、4月から1月のおよそ9ヶ月間で、今回の検定に影響を与えるほどの学習が起こらなかったことが想定される。

    　View Summary

    This is an adjunct study of Kaken Grant-in-Aid for Young Scientists (B) "Acoustic Analysis of Native Japanese Speakers' English Prosody Focusing on Listener Comprehensibility" (17K13513).    In the Kaken research, it was revealed that raters' first language does not affect the evaluation of Japanese-accented English read speech as far as they have backgrounds of phonetics or L2 pronunciation teaching. The raters were L1 speakers of 1)Japanese (n=4), 2)American English (n=4) and 3)other languages (e.g. German, French, Mandarin, Polish; n=1 each).    In the current study, we investigated whether the same consistency was observed for L1 speakers of other languages. We originally aimed to recruit Korean and Spanish learners of English but failed to recruit enough number of them. Instead, 27 Japanese learners of English (7 beginner, 12 intermediate and 8 advanced) without phonetic or English teaching backgrounds were recruited and compared to two native speakers of English. They evaluated 183 Japanese learners reading the North Wind and the Sun.    The results showed that although advanced learners accurately evaluated both segmental and prosodic accuracy of the speech (i.e. consistent with the phoneticians), beginner learners could only tell the accuracy of segments but not prosody. Also, advanced learners focused more on the prosody while native listeners focused more on the segments.

  • 日本語・中国語・韓国語母語話者のL2英語韻律比較分析

    2017  

    　View Summary

    The project aimed to compare the realisations of Second Language (L2) English stress by native speakers of Japanese, Chinese and Korean.     Previous studies (e.g. Lee, Guion & Harada, 2006; Zhang, Nissen & Francis, 2008; Kondo, 2012; Konishi & Kondo 2015) showed that Japanese, Chinese and Korean learners use different combinations of the parameters to manifest L2 English stress (i.e. vowel intensity, duration, F0 and quality).     Using corpora of L2 English by Japanese learners (n = 72) and Korean learners (n = 139), the current study compared the relative contribution of each of the four parameters by comparing the coefficients of the parameters that significantly contributed to the realisation of stress in regression analyses. Since Chinese data was not available, Japanese and Korean learner groups were compared.    The result revealed that advanced Japanese learners use more of the parameters used by native English speakers (i.e. intensity) and they relied less on the parameters used in Japanese phonology (i.e. F0). For the Korean learner group, transfer of Korean phrasal accent overrode L2 English stress and the analysis was not properly done. The future study will need to control the effect of intonational phonology in the analysis of Korean learners of English.

  • 日本語母語話者の英語の韻律の習得に関する研究

    2016  

    　View Summary

    Thecurrent project studied speech rhythm of L2 English produced by native Japanesespeakers. Among various factors of English speech rhythm, the study focused onvowel epenthesis that seems to severely impede accurate manifestation of it.    Vowelepenthesis by native Japanese speakers has been extensivelystudied in terms of the articulatory problem and L1 phonological transfer.However, it has not so much been studied in relation to speech rhythm.    Using72 read speech data of The North Wind andthe Sun in J-AESOP corpus,duration of epenthetic vowels was analysed for both beginner and advanced Japaneselearners of English.    Theresult first showed that the advanced speakers produced shorter epentheticvowels than beginner speakers, suggesting that advanced speakers’ English hasbetter rhythm. However, when we took into consideration thespeech rate, which was also shorter for advanced speakers, the statisticallysignificant difference was not observed.    Therefore, unlike the resultsof the previous studies about English reduced vowels, which are shorter foradvanced learners of English, the result of the current study shows that thedevelopmental change in vowel epenthesis by native Japanese speakers is on itsfrequency (less for advanced learners) but not on its realisation.
