SpeechJammer, winner of this year’s Ig Nobel in acoustics
Authors: Kazutaka Kurihara: [http://goo.gl/YMRce] and Koji Tsukada [http://mobiquitous.com/en/] The project web: [http://goo.gl/3ho2w] 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.
