This really bugs me in any film; when the actors can't agree on the pronunciation of proper nouns.
At the tribal council when the medicine man conjures hungry wolves from the fire, Kocoum addresses the chief and says: "Great POW-uh-tun,..."
Every other person in the film and on Disney audio products calls him "Pow-HOT-un." As a close knit group the tribe would no doubt all know how the chief likes his name said.
