Speech-Jamming Gun Unveiled By Japanese Researchers (Video)

SpeechJammerIt’s only a prototype, but if it worked for a longer amount of time, wow. Geeta Dayal writes on Wired’s Underwire:

Two Japanese researchers recently introduced a prototype for a device they call a SpeechJammer that can literally “jam” someone’s voice — effectively stopping them from talking. Now they’ve released a video of the device in action. “We have to establish and obey rules for proper turn-taking,” write Kazutaka Kurihara and Koji Tsukada in their article on the SpeechJammer (PDF). “However, some people tend to lengthen their turns or deliberately disrupt other people when it is their turn … rather than achieve more fruitful discussions.”

    Just what the prevailing authorities need to silence dissent. 

  3. this device as packaged has limitations – regardless of power, the range is limited to ~0.25 X 1150 (speed of sound in air) about 300′, the source of the speech disruption is obvious and in a public context, would have to be protected from pissed off people who actually want to hear the speaker, and can work on only one person at a time.

  4.  If you stop and think about it, this machine will not work longer than it already does.
    If you stop the voice, there will be nothing feeding into the mic, and seeing as it needs the voice going in to use as the canceller…….. it wont ever work, unless it can predict the future of whatever may be coming out of your mouth.

  5. I can’t wait to stab the first guy who uses one of these on me.

    Can we get an Industrial Strength version and position it two inches from Rush Limbaugh’s mouth?

      Couldn’t we just, I dunno, bury him alive or something?

      • What would be more fun is to just drop off a whole bunch of synthetic opiates at his house and let him do it to himself. Maybe some mislabeled Carfentanil…

    Don’t let this come to America.

  9. Since a majority have their voices focused at technology, a cell phone jammer might be a better choice.

    Sorry, Japan, but the great comedic inventor Dave Chappelle beat you to this one. Now, Wrap It Up, B!


  11. A quick look at the specs provided and the principle of operation seems to indicate that this relies on some fairly specific “automatic” reactions in the brain of the target. I have the feeling that with a small amount of training, this can easily be overcome.

  14. I would shut up if someone pointed that big box at me with a laser on it!

  15. The Soundlazer is a Kickstarter that does the exact same thing.  Check it out at http://www.soundlazer.com
