This voice in my head isn't mine!

Does any one know or ever wonder about that voice in your head?
You know, the one who's basically reading this?
Your thought voice.
Mine sounds very different from my real voice.

It's just driving me crazy that I can't find any articles about this and I've googled it so many times.
My thought voice is very highish pitch.
And I can manipulate it to sound like anothers.
But I guess we all can do that?

It just sprung to me when I got my question if deaf people had an inner voice and I thought about my own.

Oh yeah, apparently deaf people do have inner voices.
And blind people who have schizophrenia can have visual hallucinations.

Weird stuff man.
What does your thought voice sound like?
