The [ ？？] diphthong. This sound combines the aw as in law with the
ih as in sit. Though I have found in practice ， as with many diphthongs，
that the vowels within this diphthong are not quite so pure as they are
when they stand alone. So with the aw as in law ， I actually find it
to be a little closer to the oh ， as in the first sound of no. It does
assume the same mouth position， aw ， the cheeks come in a little bit
and the lips round and come out ， aw ， law， but rather than saying
an aw sound here， it's a little bit more like an oh. And to make that
differentiation in the sound， the tongue comes up a little higher in
the back than it does in the aw ， law， pure sound by itself. Oy ， o，
oy.

    The second sound： the ih as in sit. Ih ， ih ， oy. I sort feel at
times like it's ih with a little bit mix of an ee as in she though it
certainly is not oyee ， the lips don't come out that far. Oy ， oy ，
oy. So as you can see ， o， the tongue is raised in the back more so
you see the darkness in the mouth ： o， oy …… and there you see the
tongue come forward for the ih， ih ， ih. And the corners of the mouth
come out just a little bit.

    双元音[ ？？] 由law 中的[ ？] 音和sit 中的[i] 音组成，不过它的第一
个音[ ？] 更接近于[ ？：].发这个音时口腔的位置是同[ ？] 一样的，脸颊收
紧，嘴唇呈圆形并往外突，但是发这个音时舌根处要抬得略微再高些。

    第二个音[i] 中掺杂了一些[i：] 音的成分，但它绝对不像[i：] 音那样嘴
角拉得那么开。发第一个音时由于舌根抬高，可以看到口腔中的黑暗部分，而后
舌头向前伸来发[i] 音，同时嘴角要向外拉一点。
