A few episodes back, it showed Akatsuki meeting for the first time "like that" in a long time. After seeing Deidara in the manga looking all Ino-ish, you'd think he'd have a moderate to high pitch voice. But on that episode, you can hear Deidara's voice. He sounds like a damn butcher on meth or something. You can tell it's Deidara because he's saying "yeah" after everything... yeah.
