I'm with SilveryRow on this one. Unfortunately, the pronunciation of common words does differ on the US and
UK sides of the Atlantic. Posters often comment that they would (or would not) use
Barry for a boy "because it sounds like Beary", for instance. Not in British English, it doesn't. And I'm no expert on American dialectology, but I can't think of a USE word with the same o sound as in UKE
Bob and
Tom.
What I don't know is how much of a problem it is. IPA is perfect for folks with some knowledge of phonetics, but maybe they are the very people who wouldn't need that kind of help.
