Speech Jamming gadget. Colleges and schools teachers will be finding it as an gift. There will be no murmuring inside the class anymore. Yes,two Japanese researchers recently introduced a prototype for a device called "SpeechJammer" that can literally “jam” someone’s voice. Thus eventually it can stop people communicating.
Anyhow students will find a new way of communication to continue there work, but it will be actually very useful at places where the silence is must. For example hospitals, meditation halls etc.. Kurihara, a research scientist at the National Institute of Advanced Industrial Science and Technology in Tsukuba and his partner Tsukada is an assistant professor at Ochanomizu University in Tokyo were the men behind the idea.
The design of the SpeechJammer is deceptively simple. It consists of a direction-sensitive microphone and a direction-sensitive speaker, a motherboard, a distance sensor and some relatively straightforward code. The concept is damn simple. The operates on the well-studied principle of delayed auditory feedback. By playing someone’s voice back to them, at a slight delay (around 200 milliseconds), we can jam a person’s speech.
Scientist says, the gun is more effective when the delay varies in time and more effective against speech that involves reading aloud than against spontaneous monologue. Sadly, they report that it has no effect on meaningless sound sequences such as "aaaaarghhh". Being a DAF device, they can be located distant from the target. Being at a distance from the target means it’s possible to aim the device at people who are several feet away. Thus it may led to false application too.
