The 'oh' as in 'no' diphthong. The first sound of this diphthong does not occur on its own
as a vowel in American English, o, o, oh. You can see the lips have a rounded position,
o, oh. The tongue raises up a bit in the back towards the soft palate. In general, the tongue
raises some and shifts back a bit, o, o. This means the tip of the tongue, pulled slightly
back, is not touching anything. The second sound is the 'uh' as in 'pull' vowel sound,
though, in this diphthong, the lips will round more for the second sound than when the 'uh'
as in 'pull' occurs on its own as a vowel. Oh, you can see that tighter circle. The back
part of the tongue will stretch even further towards the soft palate in the second half
of this diphthong. The tip of the tongue, usually touching behind the bottom front teeth
for the 'uh' as in 'pull' vowel, may be slightly further back because it was further back in
the first half of the diphthong. Oh, no. Here we see both sounds of the diphthong. In the
first sound, you can see the jaw is dropped more. In both sounds the lips are rounded,
but they are more rounded in the second sound. Here are the two sounds in profile. Again,
note that the jaw has dropped more for the first sound. Here, parts of the mouth are
drawn in. In the first sound, the tongue is pulled slightly back and up. In the second
sound, it stretches up even more towards the soft palate. In both sounds, the tongue tip
is not quite touching the bottom front teeth. Sample words: lonely, owner, telephone. Sample
sentence: The window of the hotel was blown out and broken. Now you will see this sentence
up close and in slow motion, both straight on and from an angle, so you can really study
how the mouth moves when making this sound. The. Tongue through the teeth for the TH sound.
