Abstract: Techniques for biometric authentication using a voice accelerometer and an acoustic transducer includes receiving a first signal representing an output by a voice accelerometer of a device and a second signal representing an output by an acoustic transducer of the device. Characteristics of each of the first signal and the second signal are compared with stored biometric characteristics for a user of the device. The user of the device is then authenticated based on the comparison.
