The [əu] 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.
[əu]这个音容易与pull中的[u]音混淆，例如no一词要念作[nəu]而不是[nu]。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。
