Video Text: The [iə] diphthong. Ive seen some sources that leave this out altogether. Its always followed by an R consonant, and these sources dont see the schwa as really having its own sound, as in the ih-uh diphthong. And I say, I admit, I agree with that. Im putting in here though, because a lot of other sources use it as a separate diphthong: ih to uh -- schwa. Now, the first sound, ih. With many diphthongs, I find that the ih vowel, its written as an open ih as in sit, actually in the practice of the diphthong takes on a different color. I find it to be a lot closer to the ee as in she, though the tongue is not so far forward. I would think of the first sound of this diphthong more as a relaxed ee than as a pure ih as in sit. The second sound then is the schwa, and that sound is very quick as you are already moving into the R of the consonant that follows. So in slow motion, the sound, with the R, as it is always followed by the R, would be: iiiiihhhhhh uuuuuhhhhhh rrrrrrr: here. [iə]是一个双元音，有些材料中认为这个音是[i]和R音的组合，当中的[ə]音并不发声。但是还有很多材料中认为将它看做两个分开的元音：即[i]和[ə]。 对于第一个音[i]，很多双元音中，[i]这个元音写作短音，就像sit中的[i]，但是真的念起来的时候并非如此，它更接近于she中的[i:]，虽然舌头的位置不像发[i:]时那么靠前。其实这里的这个[i]音更像一个放松发出的[i:]而不是纯粹的sit中的[i]。第二个音便是[ə]，它出现得非常之快，刚发出你就进入到后面的R音了。如果我们用慢动作来念就是这样：iiiiihhhhhh uuuuuhhhhhh rrrrrrr。 |
