STFU Gun: Speech Jammer Stops People Talking

March 2, 2012


This is the SpeechJammer, a device that, when pointed at a person talking, will make them STFU up by playing whatever they're saying back to them loudly and at a few hundred millisecond delay, which apparently your brain can't handle. *drooling on myself* HERPA DERP?

The SpeechJammer, developed at the National Institute of Advanced Industrial Science and Technology in Japan, works because when we speak, we aren't just using our mouths as an "audio out" speaker. We actively listen to what we're saying, and the way we sound dictates how we proceed with our speech. The SpeechJammer screws with that. The "gun" shoots your words back to you, but with a delay of a few hundred milliseconds, which is enough to mess up natural cadence. The effect is called Delayed Auditory Feedback.

Admittedly, I thought ALL guns could make people stop talking. Plus start emptying their pockets. But what do I know? I'm just a man on the run from the law that rides a motorcycle and has beautiful hair and should probably have a movie made about him. HAHA -- YOU'LL NEVER CATCH ME, COPPERS! *revs bike, crashes over curb into apartment landscaping*

Thanks to Beatty and daniel, who agree they should employ these things in movie theaters. "But that would ruin the experience." I WANT TALKERS TO PUKE THEIR F***ING GUTS OUT.

    This iPhone app do the same thing

    .....I guess you will need that speaker

  • this type of effect has the opposite effect on those who have severe stuttering issues. point this gun at someone who is a chronic stutterer and they will miraculously speak completely normal. Amazing how our brain works.

    I so need this for my husband when he nags about sex!

  • Tony Ploughe

    Maybe just try being better in bed! I'm sure that would shut him up

  • I want one of these. I promise only to use it for good.

    a swift smack to the side of someones face is also very effective

    Mybe the mic's name is Mike?  I don't care, I want to try it.

     I think the poster of the article was a bit confused as to how it works... The device doesn't play your voice back at you to annoy you, it plays it back in the exact opposite phase to literally cancel it out!  Look up "Active Noise Control".

    Anti STFU Gun = Earplugs

    Anyway this is an interesting dvice. This will help silence those annoying jabber jaws.

  • Call Nobel committee ASAP!

    Srsly though, the same effect happens when you're speaking on the phone and you get feedback of your own voice.

    ...I probably gave someone the greatest idea for an iPhone app. Remember to send me a thank you note written on a $100 bill, dude!

  • Mic, not Mike ... seriously. Here's our little ad, proving we don't even know how to properly name the various parts of our product ... please buy from us! ... FAIL

  • They're Japanese! You're lucky the labels make any sense at all.
