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.

Abstract: A tooth microphone apparatus worn in a human mouth that includes a sound transducer element in contact with at least one tooth in mouth, the transducer producing an electrical signal in response to speech and a means for transmitting said electrical signal from the sound transducer to an external apparatus. The sound transducer can be a MEMS accelerometer, and the MEMS accelerometer can be coupled to a signal conditioning circuit for signal conditioning. The signal conditioning circuit can be further coupled to a transmitter. The transmitter can be an RF transmitter of any type, an optical transmitter, or any other type of transmitter. In particular, it can be a bluetooth device or a device that transmits into a Wi-Fi network or any other means of communication. The transmitter is optional.
