This is really turning into nitpicking. Nobody whined after TDK asking why Bruce would crash into Reese's car when he could have been not wearing a seatbelt and hit his head on the window and killed him. Or why Batman doesn't use a voice modulator instead of growling to hide his identity since he has all that Wayne tech. Or how Joker dressed as a 1950's nurse got into the hospital without anybody noticing. Or how was Two-Face wearing the same burned suit after he escapes the hospital when they would have cut it off his body because it was burned to his skin. Did those hurt TDK? If you look really hard, I am sure you can hate every movie ever.
He did....but they never explained it. Someone from the Nolan camp said the reason why his voice was so deep was he had a voice box thing in his suit.
And they enhanced it digitally.
But not sure if that counts because they never explained that in the movie.
And the Bumblething is simple...he's cooler without a voice.
