Louisville, KY: I've heard the local pronunciation is more like "Looville."
Gloucester, MA, northeast of Boston: "Glawsteh"
Americans.
ruf instead of roof
Probably also a dialect.
"route"
I typically pronounce it "rowte" when talking about the machining operation, or when I'm talking about the process of routing someone somewhere.
"There's a detour there that will 'rowte' you around a small town."
But if it's a path I've already taken, I'll say "root."
"I had to take a detour. That 'root' ended up taking me around a small town."
