Concepts and technologies are disclosed herein for utilizing bone conduction to detect gestures. According to one aspect, a device can generate a signal and send the signal to a sensor network that is connected to a user. The device can receive a modified signal from the sensor network. The modified signal can include the signal as modified by a body of the user. The device can compare the modified signal to the signal to determine a difference in a feature between the signal and the modified signal. The device can determine a gesture performed by the user based upon the difference in the feature between the signal and the modified signal.
