Yes, "The Batvoice" is actually a thing now, especially after the discussion that Christian Bale's growly take on Batman created. Unfortunately for fans eager to know what Ben Affleck's version sounds like, his voice is clearly being distorted by the fact that he's wearing that armoured costume. It's similar to how Robert Downey Jr. sounds in the Iron Man suit. It does seem to be clear though that this Batman will speak fairly normally and, if anything, will sound just slightly more rugged than Affleck normally does. It's not in the least big difficult to understand what he says, and if there's one well known take on the character to compare this voice to, it would have to be Kevin Conroy from Batman: The Animated Series.
