SpeechJammer Gun Gives Loudmouths a Dose of Medicine

For some of us, there are few things more exciting than a device that could get certain people to shut up. Japanese researchers created the 'new Speech Jammer gun'. Using a directional microphone, a directional speaker, and a distance sensor, the gun trips up its target by playing back their own voice to them at a slight delay of around 200 milliseconds. Researchers released a humorous video showing the SpeechJammer Gun in action, showing speakers apparently disoriented by the device.
