Abstract: A method is described including receiving real time signals from the sensor array, comparing the real time signals to corresponding training signals representing a gesture from each sensor in the sensor array to determine if a gesture has been recognized and transmitting a command corresponding to a recognized gesture to a remote computing device.

Abstract: Voice activity detection technologies are disclosed. In some embodiments, the voice activity detection technologies determine whether the voice of a user of an electronic device is active based at least in part on biosignal data. Based on the determination, an audio sensor may be activated to facilitate the recording of audio signals containing audio data corresponding to an acoustic environment proximate the electronic device. The audio data may be fed to a speech recognition system to facilitate voice command operations, and/or it may be used to confirm or deny a prior determination that user voice activity is present. Device, systems, methods, and computer readable media utilizing such technologies are also described.
