I have never heard him speak like that, and I have the original non-hacked/non-pirate version for NA. There was a pirated version, and it could've been changed. Although, the European version could be different to make his accent more like whatever region they were releasing the game to.

I don't think so. Maybe it was just the translator(s) had nothing to do and a dictionary at hand.
That's probably what happened. If not, then Cecil in FFIV has an American accent.
