A speech recognition system includes a transducer placed in direct physical contact with the user. When the user speaks, the transducer receives the speech signal from the user based on its contact with the user instead of receiving the speech signal through free air. The transducer generates an analog electrical audio signal corresponding to the speech signal. The analog electrical audio signal is then converted to a digital audio signal and transmitted to a speech recognition engine using a wireless connection. By placing the transducer in direct physical contact with the user, ambient noise in the free air may be reduced and speech recognition accuracy may be improved.
