On glide and Off glide

最近在語音學的書上讀到了一句話: The articulation of a diphthong involves a changing, complex quality in that one starting, or on-glide, vowel moves to join a finishing, or off-glide, vowel and both fuse into a distinctive vowel sound. 想請問一下 1. 這句話應該怎樣翻譯比較好呢? 2.句中提到的 "on-glide" 和 "off-glide"是什麼東西? 能不能說明一下,或是舉例說明呢? 感激不盡的啦ˋ 顯示更多 最近在語音學的書上讀到了一句話:
