Vilkas' voicetype is MaleNord. He shares it with several other marriageable characters (such as Calder). Here is a list of all marriage quotes by voicetype. Sure, maybe it's different in French, but I doubt they've recorded more different dialog. I've heard that Vilkas just sounds cheesy (?) when he speaks his marriage lines, but otherwise, they are standard.
