The [ ？？] sound does not occur on its own. It is always in diphthong
with the "uh" as in "pull" sound. For example ， 'no.' It's not 'no ，
' 'no.' To make this sound the corners of the mouth come in a little，
oh， which meant that the lips themselves press out a little bit： oh ，
oh. The tongue comes up a little bit in the back， and the tip of the
tongue comes forward， oh ， and is extremely lightly touching the soft
part of the mouth underneath the front teeth， right here.

    [ ？？] 这个音容易与pull中的[ ？] 音混淆，例如no一词要念作[n？？]
而不是[n？].发这个音时，嘴角略微向内收拢，也就是说嘴唇要向外突出。舌根
稍稍向上抬起，舌尖朝前伸，轻轻触碰门牙下侧的柔软处。
