Patent attributes
A system for confirming that a subject is the source of spoken audio and the identity of the subject providing the spoken audio is described. The system includes at least one motion sensor operable to capture physical motion of at least one articulator that contributes to the production of speech, at least one acoustic signal sensor to receive acoustic signals, and a processing device comprising a memory and communicatively coupled to the at least one motion sensor and the at least one acoustic signal sensor. The processing device is programmed to correlate physical motion data with acoustical signal data to uniquely characterize the subject for purposes of verifying the subject is the source of the acoustical signal data and the identity of the subject.
