If you’ve ever taken part in an overseas call, or dialed into a conference call using VoIP, then you’ve probably experienced a horrid delay that allows you to hear your own voice. To say the least it’s distracting, and enough in some instances that it just about causes you to shut up and in most cases forces people to end the call.

Using the very same principal, the Speeching Jamming Gun can get just about even the most chatty of people to zip their lips. It uses a distance sensor, a laser pointer, a directional mic and a directional speaker. When fired at someone – you simply pull a trigger – it captures the speakers voice and then almost instantly returns it back to them. There is a few millisecond delay, but the result is that the person hear’s their own voice. The psychological impact, as often experienced during a voice over IP call, is enough to cause someone to studder and perhaps make them stop speaking all together.

The speech jamming gun’s designers, Kazutaka Kurihara and Koji Tsukada, say the gun can work from up to 50 meters away and would be effective in libraries, commencement speeches and those alike. ┬áScary.
