Researchers Develop a Speech-Jamming Gun That Can Silence People From a Distance

Shut up, or I'll shoot

Japanese researchers have developed a gun that can silence people in mid-sentence. The Speech-Jamming gun can effectively jam the words of speakers who are over 100 feet away simply by pointing its visor at them. While countless jokes can be made about that gun (i.e. “I could use that on my wife” or “It was specifically designed for Kanye West”), the real purpose of it are not as funny. The gun is indeed being promoted as something useful to “mediate debates” or to “facilitate the quelling of protests”. There’s already “talks” of having such guns in public places such as libraries.

When there’s a way to make you physically unable to speak, we can say that free-speech is literally in danger. Like, literally. Here’s an article from ExtremeTech about the Anti-1st-Amendment device.

New speech-jamming gun hints at dystopian Big Brother future

Japanese researchers have created a hand-held gun (pictured above) that can jam the words of speakers who are more than 30 meters (100ft) away. The gun has two purposes, according to the researchers: At its most basic, this gun could be used in libraries and other quiet spaces to stop people from speaking — but its second application is a lot more chilling.

The researchers were looking for a way to stop “louder, stronger” voices from saying more than their fair share in conversation. The paper reads: “We have to establish and obey rules for proper turn-taking when speaking. However, some people tend to lengthen their turns or deliberately interrupt other people when it is their turn in order to establish their presence rather than achieve more fruitful discussions. Furthermore, some people tend to jeer at speakers to invalidate their speech.” In other words, this speech-jamming gun was built to enforce “proper” conversations.

The gun works by listening in with a directional microphone, and then, after a short delay of around 0.2 seconds, playing it back with a directional speaker. This triggers an effect that psychologists call Delayed Auditory Feedback (DAF), which has long been known to interrupt your speech (you might’ve experienced the same effect if you’ve ever heard your own voice echoing through Skype or another voice comms program). According to the researchers, DAF doesn’t cause physical discomfort, but the fact that you’re unable to talk is obviously quite stressful.

Speech jammer, in a librarySuffice it to say, if you’re a firm believer in free speech, you should now be experiencing a deafening cacophony of alarm bells. Let me illustrate a few examples of how this speech-jamming gun could be used.

At a political rally, an audience member could completely lock down Santorum, Romney, Paul, or Obama from speaking. On the flip side, a totalitarian state could point the speech jammers at the audience to shut them up. Likewise, when a celebrity or public figure appears on a live TV show, his contract could read “the audience must be silenced with speech jammers.”

Then there’s Harrison Bergeron, one of my favorite short stories by Kurt Vonnegut. In the story’s dystopian universe, everyone wears “handicaps” to ensure perfect social equality. Strong people must lug around heavy weights, beautiful people must wear masks, and intelligent people must wear headphones that play a huge blast of sound every few seconds, interrupting your thoughts. The more intelligent you are, the more regular the blasts.

Back here in our universe, it’s not hard to imagine a future where we are outfitted with a variety of implanted electronics or full-blown bionic organs. Just last week we wrote about Google’s upcoming augmented-reality glasses, which will obviously have built-in earbuds. Late last year we covered bionic eyes that can communicate directly with the brain, and bionic ears and noses can’t be far off.

In short, imagine if a runaway mega-corporation or government gains control of these earbuds. Not only could the intelligence-destroying blasts from Harrison Bergeron come to pass, but with Delayed Auditory Feedback it would be possible to render the entire population mute. Well, actually, that’s a lie: Apparently DAF doesn’t work with utterances like “ahhh!” or “boooo!” or other non-wordy constructs. So, basically, we’d all be reduced to communicating with grunts and gestures.

Download an app called Speech Zapper and try out for yourself. It's developed on the same principal as the Jap's silence gun

A baby is programmed to learn language-any language-but he isn't anymore prepared to discover a code than he is to learn Portuguese. If he were adopted by a family in Portugal, he would learn Portuguese plus not the English he usually discover from you.

Soon the U.S. government will place an order for several millions of these guns.

damn Japanese …. stop inventing evil sh*t!!

Thanks for this information, I really think this is in use here already but it helps to know the facts.

First thing I thought of was the reporters this past year, they were FINE and did not want to get checked out, remember the reports of "stress and headaches"?

Sucks for them that i know sign language, we all learn that, we'll be okay!

This version doesn't seem that ominous. If I understand it correctly, it just sends back an echo of what you are saying. This doesn't prevent you from speaking, it just makes it difficult to speak. For example, anyone who has ever heard feedback/echo of their own voice when talking on the phone…it makes it difficult to speak because you're trying to interpret what you're hearing at the same time you're talking. If you could tune it out, speaking would be no problem at all. This doesn't really seem like a weapon, or even very dangerous. In fact, if it were happening all the time, I wouldn't be surprised if people could adapt and tune it out.

Deception is like sleep: You won't realize that you're sleeping, until you wake up to realize that you've been sleeping. Same as deception, you realize that you've been deceived until you wake up to realize that you've been deceived. Rise above deception & snap out of it every1.

After watching these ya'll better make your choice/s.

F**k you SpeechJammer, f**k you! 🙁 It's societies way of silencing the people who speak about what they believe in, and things they shouldn't know. Once again, f**k you. 🙂

yeah, imagine the awkward silence from now on…

I wonder if it is responsible for burtation.

What a disgusting little 'gadget'. Should be called the 'orwell 3000'! What with the likes of this and those other abominations that fire high pitched sounds out to clear protestors you can see we're moving into potentially very dark times..

What the crap is this now!

I guess we will all go back to communicating like cavemen…grunt

Sometimes you just have to look at this stuff and laugh hysterically…

This can't be real. First off the thing is gigantic. I think this is a hoax.

They have to develop a camera to shut out desperate old dirty pervy men from the gossipy columns of trashy papers ASAP. Why they don't frequent more intellectual papers on the net instead of the trashy ones eh? Yikes just yikes. I can't stand this lot.

The Hidden Evil "This website is devoted to explaining a global program of torture, murder & persecution which I call the Hidden Evil. It includes a vast network of plain-clothed citizen informants, which is used for public stalking, & the use of Directed Energy Weapons on targeted individuals. All core factions of the community are involved, & everyone, from seniors to children, participates in Gang Stalking. Governments have used these groups in some form since the Roman Empire. The Hidden Evil is an example of this pattern repeating itself. The citizens' network patrols the streets of your neighborhoods. The evidence suggests that this network is not just part of a sub-culture within society, but that it literally permeates all aspects of it, & is therefore, part of the mainstream. As I'll demonstrate, this has happened before. The network is the creation of supra-governmental Think Tanks, which are made up… Read more »

im going to tell you all about the atrocities of the elite and illumin

Gosh nothing elitistic about pondlife. The real "elite" will be placed in heaven.

I am highly skeptical of this only because of the advertisement.. this technology may exist, but they wouldnt come right out and say you can use this gun in public to silence your teacher. that made it look like a joke and i think its bs.

"…this speech-jamming gun was built to enforce “proper” conversations."


At best, we'll have anonymous librarians being the Speech Police. Don't even want to give mental energy to worst-case scenarios.

I'm sorry, but if a librarian were to point that thing at me, i'd snatch it out of their hand and beat them over the head with it.

If there is such gun, I will use it to stop IU from singing and harming K-Pop.

No one has harmed K-Pop as much as IU.

I wish someone silences her forever.

Remember people, the technology that makes it to the public is the technology they don't use anymore! So, that means there's something more sinister is "their" nasty bag of tricks. This will be used when the world economy crashes and people are out in the streets.

Get that text-to-speech function ready on your laptops. We might all sound like Stephen Hawking, but at least we'll have a voice.

I am sure there is already a tech to stop that too.

Monstrous. It's…i don't know, probably one of the most awful creations of human kind. This thing will actually forbid free speech. Literally, we won't be able to express ourselves, express our opinions or present new ideas, because there might be someone nearby who can silence us. Stop us. Prevent us from saying something. Forbid us to speak.

Seriously, it's one of the most disgusting things i've ever heard of.
