Didn't the Dark elves in Morrowind have raspy voices due to the volcanic ash from the red mountain? Maybe in DragonBorn some Dark elves who live on the island of Solsthiem have that raspy voice since they most likely got there from Morrowind. Just a thought, correct me if I'm wrong.
I seriously hope so. I hate so much the voice of the Dunmer (and Altmer for that matter) in Skyrim.
The best voices have accents like some of the the Nords, Redguards and Imperials voice overs.
That gay sounding Aussie voice is a serious failure IMO. What in the world were they thinking?
