| Outline of Final Research Achievements |
While this project covered scientific questions that explore the mechanisms of human speech production and applied the findings to pedagogy (including lectures at educational institutions and exhibitions/workshops at science museums), the main objective has been to develop physical models that facilitate easy understanding of the speech production system. We developed smaller connected-tube models, anatomical-type models with a flexible tongue/lips and a movable mandible, a reed-type sound source with an air pump to make intelligible/loud voices stably and sanitarily, and an online activity with instructions on how to make vocal-tract models and sound sources with everyday products. They have been used in university lectures, at conferences/meetings, and in workshops, including at the National Museum of Nature and Science (Tokyo, Japan) and the Regional Science Centre, Guwahati (Assam, India). A book chapter was also published on the models and programs that we developed.

| Academic Significance and Societal Importance of the Research Achievements |
音声生成機構の解明は音声科学や調音音声学の立場からも重要で、音声教育、言語治療等にも応用されるため意義も大きい。成果は常に講演等にも反映され、国際音声コミュニケーション学会のDistinguished Lecturerとして海外６大学等の他、国際会議や国内学会の招待講演等でも声道模型を用い講演した。国内外の博物館や教育機関と連携して模型を展示・活用していただき、音響音声学デモンストレーションのサイトからは声道模型の3Dプリンタ用ファイルに加え、動画の英語版も公開した。その他、成果はNHK Eテレ「えいごであそぼ with Orton」の実験監修にも活かされており、NHK総合でも紹介された。
