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.
