Absolutely NO voice actors. I'm sorry if some are having such difficulty reading that they can't even read simple short narratives in a game they're SUPPOSED to be enjoying...
But personally I think that voice acting would be incredibly detrimental to the game. First of all... I would be very worried about WHO would be voice acting, and HOW "good" they'd be at it. Secondly... I don't think that the voice acting would EVER live up to the expectations of the majority of the fans.
See when I play the game... I already have a particular voice in mind (not really specific to any actor, at least that I know of) and I'm sure that to many other players, their choices in their heads are completely different from mine. So even if you had very good voice actors, you're going to still end up upsetting certain fans because it's a foreign voice, different from what they had in their heads, and it would change their perceptions of the characters.
To use an extreme example... would we really see Zelda as the elegant, courtly, soft spoken princess with a heart of pure gold, if she was voiced by someone with a very thick scottish brogue reminiscent of something out of the movie Braveheart? Or how about the thick accent of the Mexican cleaning lady from a couple of Family Guy episodes? (do a search, I think she shows up in a couple of episodes from volume 6 or 7) It would not be very fitting would it?
What's worse, is that, whoever did her voice acting, we as the players would never be able to replace it even for future or past games. That voice (whichever is used) would be imprinted in our heads for a long time. In Ocarina of time, to be honest, I was very disappointed with how she sounded whenever she gasped (when link got hurt) in fact, I hated it so much, I was glas she didn't talk because I was afraid to hear what she would sound as, if the full voice of the actress was used.
