| Outline of Final Research Achievements |
To address the problem of the shortage of teachers in second language learning, we have developed a Japanese language learning support system that enables self-study and cooperative learning.
In this research, we focused on three areas in particular: (1) development of a Japanese dialogue training system based on cooperative learners, (2) development of speech recognition technology for beginners of Japanese, and (3) realization of dialogue control with user profiles.
We developed a learning support system that enables learners to learn together with CLA, a cooperative learner agent, and a learning support system with a pronunciation error detection system that takes into account the pronunciations errors made by native speakers. We also developed a Japanese language learning support system with a function to recommend the next contents to be learned according to the learner's comprehension status.

| Academic Significance and Societal Importance of the Research Achievements |
現在，日本語対話訓練システムの研究は幾つか行われている．発音の評価を行うシステムなどは多く存在し商用のアプリケーションも存在する．しかし，音声対話をベースとした，日本語対話訓練システムはほとんど存在しない．本研究では，日本語を第二言語とする日本語初学者が，独学でも複数の学習者と教師がいる状況を疑似体験できる環境を構築する．これからますます日本語を学びたい学習者の数が増えていくと予想されるため，本研究で作成する音声が利用可能な日本語対話訓練用システムを開発することは非常に意義のある研究といえる．
