I've read discussions in the past about Ned's voice changing slightly. I thought it was quite noticable in episode #208. I wonder if Matt & Trey switched who does his voice, or if they're not bothering to keep it constant, or if they simply forgot how - nah! Nevermind that last one. So anyway, what could be happening here?
Or perhaps I'm completely mistaken and his voice sounds as it always has?
