How do I make my mind stop reading text in a fictional characters voice? (full Metal Alchemist)?

Hahahaha happens to me all the time. Usually I just put on some music the whole time I'm on the computer so my mind focuses on that, but sometimes it gets kinda hard to do, especially if you kno the words cuz then you keep reading what you see on the screen but it's not really sticking in your head cuz of the song you're listening to is distracting lol. But honestly, like you said, I wouldn't mind Ed's voice reading everything in my head XD. Well I guess I didn't help much, but your question was interesting so I had to say something.
