At launch, every race had 8 male and 8 female voice actors. Then Becky Ichnoski worked out how to "hack" the voiceover tools to add more variety, and these tools have now been rewritten.
According to Becky Ichnoski on ESO Live, 23rd June 2017, the Nord accent is the hardest for the voice actors to do.
