Everyone has this problem with the limited dialogue. If you look, you'll probably find another thread complaining about the same thing. And believe me, it pisses everyone off. And one person says his name, though he doesn't have a voice when he says it, it just appears along the bottom of the screen. Letty, or one of the other Besaid Aurochs, says something like, "Tidus, you can't go this way. Cap'n Wakka's waiting for you," when the team are helping to fix Kilika, near the beginning of the game. But the rest is just "Hey, you," or "him," or, maybe the most annoying ones, "the star of the Abes," and, "Jecht's blood." It makes me want to hurt something.
