SpeechJammer: Utilizing Artificial Speech Disturbance with Delayed Auditory Feedback
Last Update: 2012/09/20@


In this paper we propose a system, "SpeechJammer", which can 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 several prototypes by combining a direction-sensitive microphone and a direction-sensitive speaker, which can disturb the speech of a specific person.
