In my younger years I have been known to pronounce, in my head at least, Tanzania as I would Tasmania with the ending 'ania' pronounced the same.
The different pronunciation of another two place names occurred to me the other day, Tallangatta and Coolangatta. I rather like saying Coolangatta as I say Tallangatta. Try it yourself, with the emphasis on lang in Coolangatta.
Well, it amused me for a minute or so.
