English: How to Pronounce OH [oʊ] diphthong: American Accent

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.

Window, lips make the W shape, tongue up for the N. Teeth together for the D. And

here a quick 'oh' as in 'no' diphthong. Of, bottom lip up for the V, the hotel, again, 'oh'

as in 'no', 'eh' as in 'bed', and the tongue up for the L. Was blown, the 'oh' as in 'no',

you can see the lips rounding more at the end. Out, with the 'ow' as in 'now' diphthong.

And broken. Lips together for the B, R, and here is the 'oh' as in 'no' diphthong. Broken.

And from an angle. Tongue through the teeth for the TH. The window, lips make the W. Tongue
