Changes to Voice Actors

Why have some of the voice actors for NPCs been changed in 3.1? I'm just playing through the acts and so far I have noticed that Silk and Maramoa's voices have changed and unfortunately not for the better. Silk sounds like a bad actor trying to put on an accent and failing. Maramoa has lost her accent entirely. Why have these voices been changed? Why break something that wasn't broken?

Likely because the previous actors weren't available to do the new lines so they had to just redo the character voices (rather than have it change suddenly halfway through the game like it was in 3.0). I agree that old voices were a bit better, but the new ones probably won't be hard to get used to.

What will be jarring is some of the exile voices changing as some of their voice actors aren't available either. Hopefully the difference will not be too great when they do get around to fixing that up.
