A Shift in the Point of Articulation for Korean Consonants with an Increase of their Tensity

한국어 자음의 긴장도 증가에 따른 조음점 이동에 관한 연구

This study aims to show why and how the shift in the point of articulation for Korean consonants occurs with an increase of their tensity. From an EPG study on the point of articulation for Korean alveolar stops, fricatives and velar stops, it was concluded that the shift in the point of articulation occurs because the increase in the tensity of Korean consonants requires more contact area with the roof of mouth by the tongue, and that the direction of the shift depends on the surface shape of tongue for the plain consonant.
