To voice my support I repost my argument from the closed orc voice thread:

Something I'm mentioning all the time concerning character creation. We need something that's more than average human adventurer voices. Orc, dwarves even dragonborn Tav for me always lack immersion when they start talking. Also why is there never a voice for older people. You chose to play a wise old wizard and as soon as he opens his mouth instead of a Gandalf/Saruman styled version you get a Hogwarts student in his last semester.
