Abstract

A sound processing device (100) having means to generate a responding sound signal (25) for termination, alteration or volume reduction of the voice signal (38) is disclosed. The device (100) comprises a means for receiving sound signal (15). a means for processing the received sound signal and generating a responding signal (25). and a means for emitting the responding signal (5). The device (100) generally receives the voice signal (38) produced as a person speaks, processes the sound signal (38) and emits a responding signal (48) for cancellation, alteration or volume reduction of the sound signal (38). The device (100) aims to preserve privacy in conversation, which lacks thereof nowadays, concerning the usage of cellular phones (60) and other communication devices and prevention of eavesdropping or overhearing can be achieved. The said device (100) also aims to provide an user-enabled proactive measure to courteously prevent our conversation or speech from disturbing others around or in the vicinity.
