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.
