| Outline of Final Research Achievements |
This study examines acoustic characteristics and perceptual cues for Japanese and Korean stops and offers new insights into Korean stop consonant teaching to Japanese-speaking learners.
For Korean, following the previous study that dealt with word-initial stops, word-medial stops were analyzed to determine what the acoustic characteristics and perceptual cues for a three-way laryngeal distinction are, and VOT and closure duration were confirmed as the most dominant factors. For Japanese, VOT and post-stop fo were analyzed using data drawn from four regions, and the result showed that post-stop fo differences could explain the voiced-voiceless distinction, but not alone. The acoustic space of VOT and post-stop fo demonstrated a clear distinction between the two categories, while the effect of VOT and post-stop fo on voicing contrast differed from region to region. As for the teaching of Korean stops, a method using pitch differences was proposed and confirmed its effectiveness.

| Academic Significance and Societal Importance of the Research Achievements |
日韓の語頭閉鎖音はそれぞれ二項対立と三項対立を成し言語学的には大きく異なるが，音響音声学的にはどちらもVOTと後続母音のfoの二つのパラメータで記述することができる。両言語は語頭閉鎖音のVOTに通時的変化が起こっており，その詳細を明らかにすることは言語学への貢献はもちろん，それぞれの言語の学習者に対する音声教育にも役立つものと考える。
