"Japanese researchers have invented a speech-jamming gadget that painlessly forces people into silence," Fox News reports.

The article continues, "The device works by recording its target’s speech then firing their words back at them with a 0.2-second delay, which affects the brain’s cognitive processes and causes speakers to stutter before silencing them completely."

It can work as far as 30 feet away from a person, the story says.

In a research paper the Japanese scientists wrote, "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 stopping speaking."

The article also notes that the scientists "suggested the speech-jamming gun could be used to hush noisy speakers in public libraries or to silence people in group discussions who interrupt other people’s speeches."


  1. Personally i think it would be done too far to use such gadget in any occasion. Maybe just ask people to behave themselve will also work

  2. All the encryption procedures are so complicated that most of the people won’t simply mess with that. Under this condition, we provide two decent options available for concealing your information. The first option is to use the GSM and mobile internet jammer, which will help block the related frequencies and thus hide you for a short period. However, the drawback is that you won’t be able to make or receive a phone call. Then the second option is to avoid storing private and valuable data on your portable devices, smartphone or tablet.
