The [au] diphthong. The first sound of this diphthong is once again a sound that does not stand on its own as a vowel sound in American English. However, it is very similar in sound to the aa as in bat. The way it is different from that sound is that the jaw on aa, aa, is tighter. And on aa as in ow, it drops more. In that way, it is similar to the ah as in father. Also, as you can see, aa, there's the lift here, and it's not quite as extreme in the 'ow', 'ow'. In that sense, the lips are also like the ah as in father. The tongue however, aa, ow, is similar to the aa as in bat in that it's raised in the back and then comes forward, and that's what you see.

The second sound is written as the uh as in pull. I do find, however, that it tends to taper a little bit towards the oo as in boo without the lips actually coming into that position.

[au]是一個(gè)雙元音，它的第一個(gè)音并不像它本身所寫(xiě)的那樣念作[a]，但是卻和bat中的[?]音很相近。它倆的區(qū)別在于：發(fā)[?]音時(shí)下頜收得緊些，嘴角有明顯的上揚(yáng)；而發(fā)[au]中的第一個(gè)音時(shí)是下頜要下垂一點(diǎn)，嘴角沒(méi)有那么上揚(yáng)。不過(guò)發(fā)兩個(gè)音時(shí)，舌跟都要抬起然后向前舒展。[au]的第二個(gè)音寫(xiě)做pull中的[u]，但是它更接近于boo中的[u:]音，但是唇形沒(méi)有收得那么緊。

cow 奶牛

bough 大樹(shù)枝

Sample sentence:

I came back from vacation and found my flowers dead and brown. 度假回來(lái)發(fā)現(xiàn)我養(yǎng)的花已經(jīng)死了，都變成棕色的了。
