【大家一起學發音】[ɔi]該怎麼發(視頻)

ing-bottom: 100%;">

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.

雙元音[ɔɪ]由law中的[ɔ]音和sit中的[i]音組成，不過它的第一個音[ɔ]更接近於[ɔ:]。發這個音時口腔的位置是同[ɔ]一樣的，臉頰收緊，嘴脣呈圓形並往外突，但是發這個音時舌根處要擡得略微再高些。

第二個音[i]中摻雜了一些[i:]音的成分，但它絕對不像[i:]音那樣嘴角拉得那麼開。發第一個音時由於舌根擡高，可以看到口腔中的黑暗部分，而後舌頭向前伸來發[i]音，同時嘴角要向外拉一點。
