Speech-Jamming Gun

SpeechJammer is a system that can be used to disturb people’s speech. In general, human speech is jammed by giving back to the speakers their own utterances at a delay of a few hundred milliseconds. This effect can disturb people without any physical discomfort, and disappears immediately by stop speaking. Furthermore, this effect does not involve anyone but the speaker. We utilize this phenomenon and implemented two prototype versions by combining a direction-sensitive microphone and a direction-sensitive speaker, enabling the speech of a specific person to be disturbed.

  1. This was a well-known phenomenon at the radio station I used to work at back in the late 70’s. A favorite engineer prank was to intercept the on-air announcer’s headphone monitor feed and run it through a tape delay while they were trying to read the news.

    We called it,’The Stutterphones.”
