Abstract

his study examines whether the yoo-on ( ) in Japanese is the palatalized singleton [Cj_{], the}

consonant-glide sequence [Cj] or the diphthong [CiV] from the view point of the lip shapes and the artic-ulatory movements of the tongue. The results show that the yoo-on has the [CjV] structure.

Keywords — consonant, palatalization, sylla-ble structure, lip shapes, Electropalatograpy, Japanese
