Many of my accent reduction coaching clients get confused about how to pronounce the letter O in American English.

And it’s no wonder!!!

The O has at least  five different sounds in spoken English. Here are a few examples:

/ow/ as in rose
mobile
home
phone

/ɑ/ as in olive
content (n )
process, processor
problem, problematic

/ʌ/ as in mustard
love
some
one, once

/uw/ as in blue
do
move, remove
lose

/er/ as in purple
work
worry
world

I use The Color Vowel Chart to teach the 15 American English vowel sounds to my clients.

Just for fun, I’ve added four of the sounds of the letter O to this info-graphic. Click on the info-graphic to enlarge it in a new frame.

Th letter O is a tricky vowel to master, but you can learn to pronounce the sounds of O and the other 14 American English vowel sounds in my iBook, American Accent Fundamentals.

This iPad book for accent reduction is now available in the iBookstore.
