The [ ？：] sound. This aw is very similar to the [ ɑ：] as in father，
which is a little more open ， ah. Aw. You can see， there is a shift
in the lips ， and also the cheeks come in a little bit. Ah ， father ，
aw， law. So， the coming in of the cheeks kind of makes this a little
bit longer and the lips come out just a little bit. Ah， aw. There is
also a very subtle change that happens with the tongue. In ah as in father，
it's laying. And it continues to lay on the aw law， but the difference
is， in the back， it shifts back a little bit. It shifts back towards
the throat. Ah， aw. And that changes the color just a little bit.

    [ ？：] 這個音非常接近father一詞中的[ ɑ：] 音，不過發(fā)[ ɑ：] 的時
候嘴要張得更大些，ah. aw，就像大家看到的這樣，唇形有所變化，臉頰也略微
往里縮。ah， father. aw ， law. 臉頰往里縮使得aw這個音有些被拉長，另外
嘴唇要稍微向外張。ah，aw. 再有，發(fā)這兩個音時舌頭也是有細(xì)小變化的。在發(fā)
father中的ah時，舌頭是平放著的；雖然發(fā)law 中的aw時，舌頭也是平放著，但
是區(qū)別在于后部。發(fā)aw時舌頭要向后移一些，也就是向喉嚨處移動。ah， aw.就
是這樣造成了聲音的細(xì)微差異。
