Exactly! It doesn't have to be weird if you're, for example, playing a 60-year-old grizzled warrior who's spend a lifetime drinking and smoking but has the voice of a fresh-faced 20 year old. Not to mention the gamut of voice depth different people have. If the voice is in your head it can be anything you want. I did like Commander Shepard in ME, but again, Shepard was a very defined character. There wasn't a lot of role play flexibility--Shepard was always Shepard. But I'm sure my tiefling is worlds apart from your dwarf.
