    Tsuneo Kato; Mariko Sugahara; Seiichi Yamamoto
    日本語を母語とする小中学生の英語音声について身体的・知能的な発達,学習プログラム,言語的背景との関係性を明らかにするため,2016年から数十名規模の英語音声収録を継続してきた.2021年度は新型コロナウイルスが比較的収まった時期に,中学3年生約40名と小学2年生約60名の英語音声収録を再開した. 2019年度に収録を行った中学1年生37名には,国内で日本語による初等教育を受けた生徒(JP),国内で日本語と英語によるバイリンガル初等教育を受けた生徒(BP),外国で英語による初等教育を受けた生徒(EP)がバランスよく含まれ,英語の発音に明らかな違いがあった.そこで,無強勢母音の発音に焦点を当てて3群の比較分析を行った.分析の結果,EPは無強勢母音のスペクトル品質を強勢母音のそれと区別し,一方で無強勢母音の表記には強い影響を受けていなかった.JPは,無強勢母音のスペクトル品質を強勢母音のそれと区別できておらず,一方で無強勢母音の表記に強い影響を受けていた.BPはEPとJPの中間であったが,語によってEPに近い発音とJPに近い発音が確認された. 韻律自動評価手法について,任意の英単語に対して語彙強勢を踏まえた韻律評価を可能にするため,入力の時系列情報間の離れた依存関係を捉えられるニューラルネットワーク技術Transformerを用いる自動韻律評価手法を考案した.日本人大学生による英単語および英語短文発声において,英語母語話者による主観評価値との相関係数を従来の決定木に基づく手法に比べて大幅に改善した. 小学生の英語音声の分析成果について国内学会で2件発表し,自動韻律評価について国内学会で3件発表した.第二言語音声獲得に関する国際会議New Sounds 2022の採録通知も受けたがコロナ禍により現地参加が叶わないため採録を辞退した., Japan Society for the Promotion of Science, Grants-in-Aid for Scientific Research Grant-in-Aid for Scientific Research (C), 2020/04 -2023/03, Principal investigator, Grant-in-Aid for Scientific Research (C), Doshisha University
  • Joining-in-type CALL system using dialogue agent
    Yamamoto Seiichi
    Automatic speech recognizer (ASR) is indispensable for dialogue-based computer-assisted-language learning (DB-CALL) system to give learners adequate corrective feedback. However, ASR of the second language learners is still a challenge, because their speech contains not just pronouncing, lexical, grammatical errors, but is sometimes totally disordered. This research proposed a novel DB-CALL system using two conversational agents, one as a teacher and the other as an advanced learner. The system is designed to simulate multiparty conversation, expecting implicit learning and enhancement of predictability of learners' utterance through an alignment similar to "interactive alignment" observed in human-human conversation. The experiment demonstrated that repetitive queries of specific grammatical expressions consistently improved the correct use of the expressions than simple single query, and also suggests that its retention effect is higher than conventional repeating training., Japan Society for the Promotion of Science, Grants-in-Aid for Scientific Research, 2019/04 -2022/03, Grant-in-Aid for Scientific Research (C), Doshisha University
