大家一起学发音：[u]该怎么发

The [u] sound. This is very related to the [ʌ] as in butter, but there's a difference in the tongue position, and a difference in the lip position. What the tongue does, is it comes more forward than it does for the uh {butter} sound, and it also raises a little bit in the back. But it doesn't touch the roof of the mouth. Uh, uh. So it comes up a little bit in the back and then forward. The lips, as you can see, uh, they come out a little bit, and the corners come in just a little bit. Uh {butter}, uh {full}, uh {butter}, uh {full}. Uh, butter -- uh, should, could, full.
