TOKYO (Newscore) - Japanese researchers have invented a speech-jamming gadget that painlessly forces people into silence.
Kazutaka Kurihara of the National Institute of Advanced Industrial Science and Technology, and Koji Tsukada of Ochanomizu University, developed a portable "SpeechJammer" gun that can silence people more than 30 meters away.
The device works by recording its target's speech then firing their words back at them with a 0.2-second delay, which affects the brain's cognitive processes and causes speakers to stutter before silencing them completely.
Describing the device in their research paper, Kurihara and Tsukada wrote, "In general, human speech is jammed by giving back to the speakers their own utterances at a delay of a few hundred milliseconds. This effect can disturb people without any physical discomfort, and disappears immediately by stopping speaking."
They found that the device works better on people who were reading aloud than engaged in "spontaneous speech" and it cannot stop people making meaningless sounds, such as "ahhh," that are uttered over a long time period.
Kurihara and Tsukada suggested the speech-jamming gun could be used to hush noisy speakers in public libraries or to silence people in group discussions who interrupt other people's speeches.
"There are still many cases in which the negative aspects of speech become a barrier to the peaceful resolution of conflicts," the authors said.
I think one serious limitation of the device is that the subject actually has a working brain.
Or be president. Look for this at the White House press conference.
I’ve seen a talkshow host do this to his guest. He fed the guy’s voice back into his headphones with a slight delay. The effect was immediate and impressive...he started slurring his speech and then he stopped speaking. The slurring effect was pretty hilarious actually.
Now why did you want to hurt me like that? What have I ever done to deserve this?
Now if they could make something that zaps ugliness there would be no more liberals.
Unfortunately, the target must possess a minimum number of functioning brain cells and be capable of hearing their own bulls*** in order for the device to be effective. Rep. Jackson Lee and most of her colleagues are going to be immune.
This has happened to me when my cell phone connection feeds back my own speech. I’ve learned to power through it by ignoring the incoming sounds. You really can train yourself to be “relatively” unaffected by this, but it takes cpu (brain) cycles to do it.
Don't the occutards already do something similar with their annoying "people's microphone"?
This is more similar to someone not turning off their radio when calling a talk show and getting confused with the feedback. The response is to just plug your ears and go on talking
I do this all the time to my brother! When he is ordering from a take-out window I repeat exactly what he is saying as quickly as I can as he is saying it. It utterly confuses him and he can’t think of what he is saying.
Hee Hee, don’t you just love Friday surprises. :)
WHAT THE.... ?!
A similar effect happens when people call in to talk shows, and leave their own radio on. In that case the delay is several seconds, but the feedback makes it very difficult to keep talking. I can see this being quite effective, especially if they’ve worked out some “ideal” amount of delay to maximize the effect.
This guy would definitely want one of these.
Hee Hee, dont you just love Friday surprises. :)/
I think I saw her on an episode of NatGeo. It was about cavepeople. I have always thought she wrote with a poison hammer and chisel. :)
WOw, can they imbed that technology in a teleprompter?
Yeah, I noticed that happened on my cellphone a few times and it was annoying enough that I powered through a couple more sentences and ended the conversation. Not sure what length of time that cellphone feedback was. Maybe that .02 second delay discovered by Kazutaka Kurihara and Koji Tsukada is the perfect length of time to really just shut you down.
this is nothing, my Wife can silence me before I even open my mouth
I want one! Do they have a version for dogs???
Well, most women have always had the power to silence men within visual range, but this gizmo doesn’t require them to lift up their shirts.
