I would just pronounce it like "coke" and it would just sidestep the whole pronunciation issue. I'm not sure how most people pronounce it but that's what I would do to talk to my boss about it.
Btw, why is it "pronUnciation", but "pronOUced". English is hard.
In Australian English, it is "pronOUNCiation"
BTW, in case there has been some confusion here, since the topic was how things were said, I have been assuming this is what the person I was replying to was talking about, not spelling.
Actually, this varies with dialect. Route can be pronounced either way: |ˈrüt| or |ˈrau̇t|
