Video Text:

The [ai] diphthong. This combines the ah as in father and the ih as in sit. Aahh-iihh. In the ah vowel, the tongue is very relaxed, so the front is just kind of sitting there. Ah. However for the ih, it moves up a little on the back of the teeth. Aahh-iihh. So I would say the emphasis goes from the back of the tongue to the front.

[ai]這個(gè)音包含了father中的[a:]音和sit中的[i]音。發(fā)[a:]時(shí)舌頭非常放松，舌尖基本就是躺在那里。但是到了[i]音時(shí)，舌尖要略微上臺(tái)，觸到齒背。所以我們可以說發(fā)[ai]時(shí)，重心是從舌根慢慢轉(zhuǎn)移到舌尖。
