Want to be the kind of person who causes entire rooms to fall silent when you enter? Researchers from the National Institute of Advanced Industrial Science and Technology in Tskuba and Ochanomizu University in Japan have created a speech jamming gun that takes the words right out of speakers’ mouths using a clever trick of psychology.
Psychologists have long known that for whatever reason, it’s very difficult to talk when your words are being immediately repeated to you. Not annoying-younger-sibling repeated to you, but spit back at you just a fraction after you’ve spoken. So by using a simple directional microphone and speaker device, the researchers have created a handheld “speech jammer” that records what a person is saying and repeats it back at them with a two-tenths-of-a-second delay.
In tests, the researchers said the device works well at a distance, rendering the person at the receiving end without causing any physical discomfort (nevermind the mental discomfort caused by suddenly being rendered mute). The only limitation is that it only works with words; meaningless syllables like those often expressed by pirates or onomatopoeia don’t necessarily work.The researchers see it as a tool to maintain order in meetings or discussion groups where someone is trying to dominate the conversation. But the commercial applications are virtually endless, as there are obvious applications for anyone who ever plans to get into a relationship with another human being ever.
Five amazing, clean technologies that will set us free, in this month's energy-focused issue. Also: how to build a better bomb detector, the robotic toys that are raising your children, a human catapult, the world's smallest arcade, and much more.

Pltzzzzz!

oh yes, this would be so fun to have... I'm laughing at the possibilities already
Here’s how National Institute of Advanced Industrial Science and Technology in Tskuba and Ochanomizu University in Japan can make all the money they will ever need as long as they exist.
1. Create a unit that integrates into other devices such as a TV or computer. Or make an app for iPod /Pad like devices.
2. At the push of a button on it activates, rendering your wife/ girlfriend/ mother/ mother-in-law speechless.
3. Market to men and hire some people to help you manage the billions that will be in your bank account by tomorrow morning.
I would love to see this used by moderators during political debates.
I used to use a STU-III phone that would do this after I would go secure. I could hear my own voice through the receiver with a fraction-of-a-second delay. The first time I used it, I stammered like an idiot for a full minute. Not my best first impression. I got used to it over time, although it always took extreme concentration to ignore what I was hearing and speak plainly.
"The researchers see it as a tool to maintain order in meetings..."
If a person is consistantly speaking out of turn during a meeting, then ask them to leave. No technology required. If they refuse to leave, they are not going to be pacified by being involuntarily placed in the "cone of silence". More likely, someone is going to get punched in the mouth.
"The only limitation is that it only works with words; meaningless syllables like those often expressed by pirates ..."
Reason number 32,467 to be a Pirate...
The ultimate weapon to use against nagging women.
The technology is not silencing a person; but over powering them with reflective conversation and not allowing them to continue speaking.
If I blast a air horn, I can accomplish the same thing and extremely less cost.
So to the wonderful technology I say again,
pltzzzzzzz, the raspberry!
It is inventive to do, but I think these engineers could have spent their time doing much productive goals.

They can't take the words right out of my mouth--I use ASL to communicate.
So much for freedom of speech......if Obama got his way he would pull out this gun on every man woman and child.
I would love to shut up somebody with this thing.
Well! Finally someone has thrown some light on the inability of radio talk show callers to speak while their radio is on in the background.
If I had one of these, I'll put it on my balcony and switch it on 24 hours a day to shut up my noisy neighbors.
@contoria
Actually they different "noise cancelling head phones" detect outside sound and apply sound at a frequency that cancels out the external sound while leaving the sound you want to hear intact. AKA physics
this uses a psychological phenomenon.
So completely different......
I could see some serious downside to this device. Say someone used it at a key moment in a presidential debate? Or Dictators using it at public rallies? The ability of someone to speak well in public has huge impact on how others perceive them and their ideas.
I want one of these! This has got to be one of the best inventions in a long time. Personally, I think that the fact that human beings can talk is an over-rated phenomenon. Some people talk way too much and have nothing to say. And some people use words like weapons to hurt others, parents who berate their own children are the worst.It would be a better world if more people kept their mouths shut unless they had something positive, intelligent or really important and interesting, or even something funny to say. But, until then, let's get this thing mass produced!
That's nothing new! Sometimes you get it in the cell phone due bad conexion; you listen your voice in an annoying echo so makes you stop talking.
You know now that I think about it my friend who's a detective has a gun that can do the same thing but the effects last much longer.
"In tests, the researchers said the device works well at a distance, rendering the person at the receiving end without causing any physical discomfort."
I would think being rendered would be quite painful..... Otherwise, i think they might be missing an adjective somewhere in this sentence.
@Atomicsockbomb
I once saw a guy get tazed in the larynx too, that seemed pretty effective.
So, we do this with a computer and it's legal, but if I thwack you on your Adam's Apple it's not. We can permanently ban what you were going to say if we attach it to your ID. We can keep ANYTHING ABOUT YOU from ever being uploaded; and if it ever is, comes only to a runtime environment but never the web. At least if I bashed someone in the head with the 'ol forget-me stick' the bashee would eventually have SOME chance to recall that they liked applesauce and had wanted to share a recipe once.
