They are playing the sound back without alteration,juist 0.2seconds after they've spoken it, which confuses the brains audio/language center, and makes it very difficult for them to continue talking, so they shut up.
Its a psychological effect, not a physical one.edit on 4/3/2012 by BMorris because: Typo correction

I'll tell you one thing.
If I was in a library, or wherever, and somebody pointed this device at me, I would walk up to the person, take this device, and promptly smash them over the head with it.
I'm quite serious.
