【英语启蒙】大家一起学发音：[ɔi]该怎么发

The [ɔɪ] 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[ɔɪ]由law中的[ɔ]音和sit中的[i]音组成，不过它的第一个音[ɔ]更接近于[ɔ:]。发这个音时口腔的位置是同[ɔ]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。
