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. See detail in our paper on the pre-print server: http://arxiv.org/abs/1202.6106

I think they will also shut up if you point at them with a regular gun.

It doesn't work for me. I downloaded the program, I even played with the MS delay settings and attempted various times. I surpass Speech Jammer!

i'd be more likely to buy it if it were smaller and more compact. hopefully this is just a prototype.
