On one of the Star Trek DVD's Sirtis talks about her accent. She was apparently instructed to come up with something "new" to be a Betazoid accent. Then, of course, Rodenberry's wife showed up as her mother and screwed the whole thing up. But I think the point is that she wasn't trying to sound American.
