How to make this sound:

Video text:

The oh 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.  Oh, oh.  Sample words:  no, go.  Sample sentence:  Mr. Stone shows off his snow mobile.

This sound comines the closed oh, which in American English does not occur outside of this diphthong, with the 'uh' as in 'pull' [] sound.
