Abstract
Technologies are described herein that allow a user to wake up a computing device operating in a low-power state and for the user to be verified by speaking a single wake phrase. Wake phrase recognition is performed by a low-power engine. In some embodiments, the low-power engine may also perform speaker verification. In other embodiments, the mobile device wakes up after a wake phrase is recognized and a component other than the low-power engine performs speaker verification on a portion of the audio input comprising the wake phrase. More than one wake phrases may be associated with a particular user, and separate users may be associated with different wake phrases. Different wake phrases may cause the device transition from a low-power state to various active states.

24. A computing device, comprising:
-
a microphone; and a low-power engine to; recognize a wake phrase in audio input provided by a user to the microphone while the computing device is in a low-power state; verify the user based at least in part on a portion of the audio input comprising the wake phrase while the computing device is in the low-power state; and cause the computing device to transition from the low-power state to an active state. - View Dependent Claims (25, 26, 27, 28, 29)
