Technology That Can Make Someone Hear Voices

Is there some kind of machine, toy or game that can make a person hear voices and possibly read their thoughts?

Not as far as I’m aware of. There is a toy, the Ouija board, which can give the illusion of contact with “other voices”, if you enjoy that kind of thing. But it’s a trick.

Here’s a link to a Skeptical Inquirer online column by Kenny Biddle which might answer your question. Scroll down to the one titled, “Groundbreaking Experiment Breaks No Ground”.

Reminds me of a solution to a bumper sticker I once saw: “You’re just jealous because the voice aren’t talking to you.”
