Indeed, should Jar Jar talk in the same high pitched voice but in a different language? The current voice doesn't bother me as much as long as Ahmed Best is keeping the conversation straight forward. The squealing is what gets on my nerves. Putting the voice in a different language would eliminate that much maligned 'Stepin Fetchit' aspect. I think the voice needs to keep some of the original tone, or the shock of something new will drive folks bonkers. Remember the outcry at Anakin's dub? I'd say that Jar Jar's voice needs to be different, but familiar. Or as George would say, "Same thing, only better!"
