ABSTRACT:
A two-way communication system particularly valuable for noisy environments where a user has a tooth bone conduction microphone in his mouth normally controlled by a tongue switch that transmits an electrical signal representing speech to a retransmit module usually worn on the user's body or mounted on an earphone or headset where the speech electrical signal is retransmitted to a second user usually by RF. The retransmit module can also receive signals from the second user and transmit them to the earphone or headset thus providing two-way communication.
