Abstract: A handheld foldable voice-muffling device using passive noise silencing materials to dampen noise and a microphonic transceiver to transmit a user's speech and receive incoming signals allowing him to wirelessly communicate with another person or other communication devices without causing a disturbance to others in his surrounding area.

Abstract: An invention for eliminating the noise generated by a user speaking into a microphonic instrument is disclosed herein. In a first embodiment, the invention comprises a soundproofed housing arranged to cover a user's mouth region and a loudspeaker that outputs a processed sound wave having a phase that is opposite of the user's voice thereby canceling out the user's voice that was confined inside the housing. In a second embodiment, the invention comprises a soundproofed housing arranged to enclose a user's mouth area, a microphone to capture the user's speech, and a loudspeaker that outputs a processed sound wave having a phase that is opposite of the user's voice thereby canceling out the user's voice that was confined inside the housing.

Abstract: A language translation device having a contour shaped housing that covers the mouth area of a user thereby substantially preventing said user's speech from being heard by a person who speaks a different language thus enhancing realtime speech-to-speech interpretation. Said device comprises a microphone to capture a user's speech that is transmitted to a language processing system and a loudspeaker to output a received translated speech for said different language person to hear.

Abstract: A wireless hands-free language translation device in accordance to a headset configuration which when used swivels said device inwards to cover the mouth area of a user wherein such arrangement prevents the person spoken to from hearing most of the user's voice. Said device comprises a microphone to capture speech, a transceiver to transmit and receive signals, and a loudspeaker to deliver a received translated speech to a person other than said user.

Abstract: A foldable handheld communication device with a clamshell housing which when used is unfolded to cover the mouth area of a user wherein such arrangement allows said device to be portable and be stored in a pocket or purse. Said device comprises a microphone to capture speech, a transceiver to transmit and receive signals, and a loudspeaker to deliver a received translated speech to a person other than said user.
