Outline of Final Research Achievements

Numerous theoretical and/or practical problems make it challenging for teachers, researchers and policymakers to assess speaking proficiency in contexts that reflect real conversational situations. Using automated speech scoring technologies is one way to alleviate these problems. This study set out to build and evaluate a new system for automatically assessing learners’ speech within the context of an oral Discourse Completion Task (DCT). The DCT was administered to 210 undergraduate students of intermediate English language proficiency. The results show that the exact agreement between human and machine scores was moderately high, 72 %. This value is comparable to the extant literature on automated speech scoring and could serve as a foundation upon which to explore the applicability of the system in classroom settings. Areas for improvement in prediction accuracy and possible ways of untilising the current system in pedagogical settings are discussed.

Academic Significance and Societal Importance of the Research Achievements

今日、音声認識技術に加えて表情やモーションキャプチャーの技術も搭載し、バーチャル・エージェント(virtual agent)と英語で学習を進める双方向(やり取り)型の学習支援システムの開発・運用が進んでいる。しかし、(「学習」ではなく)自動「採点」(=「話す」能力の測定)において、継続・発展性のある文脈が用いられている例は皆無に近い。本研究では、今日の外国語教育で重視されている、文脈や目的に応じた情報の理解と伝達が求められる談話完成タスクを用いた自動採点のシステム構築・精査に取り組み、外国語教育における自動評価の運用の可能性について検討・提案を行える点で学術的・社会的意義に富むと言える。
