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.

Suffice 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.
