How to Build a Speech-Jamming Gun (SpeechJammer: Artificial Speech Disturbance)

How to Build a Speech-Jamming Gun

Japanese researchers build a gun capable of stopping speakers in mid-sentence.

Photobucket

The drone of speakers who won't stop is an inevitable experience at conferences, meetings, cinemas, and public libraries.

Today, Kazutaka Kurihara at the National Institute of Advanced Industrial Science and Technology in Tskuba and Koji Tsukada at Ochanomizu University, both in Japan, present a radical solution: a speech-jamming device that forces recalcitrant speakers into submission.

The idea is simple. Psychologists have known for some years that it is almost impossible to speak when your words are replayed to you with a delay of a fraction of a second.

Kurihara and Tsukada have simply built a handheld device consisting of a microphone and a speaker that does just that: it records a person's voice and replays it to them with a delay of about 0.2 seconds. The microphone and speaker are directional so the device can be aimed at a speaker from a distance, like a gun.

In tests, Kurihara and Tsukada say their speech jamming gun works well: "The system can disturb remote people's speech without any physical discomfort."

Their tests also identify some curious phenomena. They say the gun is more effective when the delay varies in time and more effective against speech that involves reading aloud than against spontaneous monologue. Sadly, they report that it has no effect on meaningless sound sequences such as "aaaaarghhh".

Kurihara and Tsukada make no claims about the commercial potential of their device but list various aplications. They say it could be used to maintain silence in public libraries and to "facilitate discussion" in group meetings. "We have to establish and obey rules for proper turn-taking when speaking," they say.

That has important implications. "There are still many cases in which the negative aspects of speech become a barrier to the peaceful resolution of conflicts, " they point out.

Clearly, speech jamming has a significant future role in contributing to world peace and should obviously be installed at the United Nations with immediate effect.

I’m sure that this is teleprompter-compatible. In my version of a bureaucracy that produces thousands of pages of regulations a year, mandating every teleprompter to be equipped with one would be top priority.

I would be curious to experience this myself. Can’t be that hard to create a tool to record and play delayed by 0.2 sec.

And the Senate.

And wherever Puhlousey is

Back in the old days, before effective echo-cancelers, talking on the telephone via satellite could be difficult because of the delayed echo. I have experienced the effect.

However. You can condition yourself to ignore it with practice.

i have this problem in the communications room in my office. The idiot that programmed our phone system has the two phones on the console on separate numbers. The result is that when you page somebody your voice comes out of the other phone a fraction of a second later. I have to plug that ear in order to make a page.

Looks like this same idiot is messing with your postings too!

I’m wondering if they could get this thing downsized a bit and built into the TV remote?

A speaker [(1100f/s) * (0.2s) = 220f] away from you and a mic?

The real irritating part is when, after a few seconds it says “Turn down your radio, caller!”

Closely mocking a speaker is a venerable method of discombobulating same. This simply mechanizes the mocking.

110 feet away. You have to account for the return travel time of the rebroadcast from the speaker.

Will not work on progressives. They are constantly engaged in self-parody.

With modern sound processing capability, you could shift the speaker’s voice pitch to a shrill region (or for a shrill speaker, to a boomy region) before playing it back to him/her. That would annoy.

It doesn't take sophisticated equipment. I was on a conference call this week. A co-worker in the adjacent office decided to call into the conference. He turned his speaker phone on. It didn't matter when we were all listening. When it was my turn to speak, my words round-tripped through the conference bridge and were audible through the wall from the adjacent office. It was just impossible to finish a sentence. I had to have him go off the speaker phone to continue.

Mystery over KCBS TV reporter's gibberish outburst at Grammys

KCBS TV reporter Serene Branson has told her TV bosses she is feeling fine despite concerns she had suffered an on-air stroke after talking gibberish in her live post-Grammys Award report.

Serene Branson garbles her words (Picture: KCBS)

 

News Reporter Talks Gibberish

 

Judge Judy, 4th to Talk Gibberish On Air…What is Wrong With People on TV?

 

Rick Perry looses train of thought in debate:

 

Just speculation, but I think somebody out there may be up to no good.  Could their have been devices hidden in the cameras that caused these speech disturbances?  And if so, were they testing and/or proving the effectivness of their devices to their..  lets say.. benefactors in high places?  Will they try something similar to this when the republican candidate debates obama during the election?

Just speculation.

Isn’t this how the ‘Peoples’ Mike’, beloved of the #OWS crowd, works? It disrupts a speaker by playing his own words back to him.

That is easily and quickly fixed if you have a good telephony company. Our family has been in that busines for over 30 yrs. And they should be able to do it remotely.

That would be easier if I didn’t have a government job, with a government telephone guy. The same people that are supposed to provide you with bandwidth deny your bandwidth requests, then steal your bandwidth to install a VOIP phone system.

Sounds like the perfect machine for the OWSers to use in their goofy echoing of the speaker’s message. Just think how much more efficient this would be — much faster echoing, no people unclear if they are repeating the right words, all the echos in proper unison, avoided strain on vocal chords. But that would lead to unemployed OWSers, so this machine should be destroyed immediately.

Jokes aside, liberals DO actually have techniques that they train their spokespeople with,

one of those techniques is called “jamming”,
and it involves continuing to speak out of turn and not letting the opposition get their point out.

Liberals are not constrained by the concept of “decency” or “politeness”. The only morality they adhere to is Nietsche’s “Will to Power”.

What type of VOIP phone system do you have? If you knew how, could you reprogram the phone to shut off the speaker?
