1. A method for activating an electric device from a standby power mode, comprising:
- (a) receiving an audio stream in the electric device when in standby power mode;
(b) digitizing the audio stream to an audio pattern when in standby power mode;
(c) comparing the audio pattern digitized in said step (b) to a digitized activation phrase stored in a non-volatile memory when in standby power mode;
(d) activating the electric device where the audio pattern matches the activation phrase to within a predefined tolerance; and
(e) confirming the audio pattern matches the activation phrase, after activation of the electric device in said step (d), using resources available to the electric device when activated.

Abstract
A system and method are disclosed for activating an electric device from a standby power mode to a full power mode. The system may include one or more microphones for monitoring audio signals in the vicinity of the electric device, and a standby power activation unit including a low-power microprocessor and a non-volatile memory. Audio captured by the one or more microphones is digitized and compared by the microprocessor against predefined activation pattern(s) stored in the non-volatile memory. If a pattern match is detected between the digital audio pattern and a predefined activation pattern, the electric device is activated.

11. A standby activation system for activating an electric device from a standby power mode, the standby activation unit comprising:
-
one or more microphones for detecting an audio stream in a vicinity of the one or more microphones; and a standby activation unit, including; a non-volatile memory including one or more stored activation patterns, and a processor for comparing a digitized audio pattern received from the one or more microphones to the one or more stored activation patterns stored in the non-volatile memory using power available to the electric device in standby power mode, the processor activating the device if the digitized audio pattern matches an activation phrase of the one or more activation phrases stored in the non-volatile memory to within a predefined tolerance, and the processor reverting the electric device to standby power mode upon activation if resources available to the electric device when activated do not confirm that the audio stream was a spoken activation command. - View Dependent Claims (12, 13, 14, 15, 16)

17. A method for activating a computing device of a NUI system from a standby power mode, comprising:
-
(a) receiving an audio stream in one or more microphones associated with the NUI system when in standby power mode; (b) digitizing the audio stream to an audio pattern when in standby power mode; (c) processing the digitized audio stream to facilitate matching of the digitized audio stream with one or more digitized activation phrases stored in a non-volatile memory of the computing device when in standby power mode; (d) comparing the audio pattern processed in said step (c) to one or more digitized activation phrases stored in the non-volatile memory of the computing device when in standby power mode; (e) activating the computing device where the audio pattern matches an activation phrase of the one or more activation phrases to within a predefined tolerance; and (f) confirming whether activation was intended after the computing device is activated in said step (e) upon a match between the audio pattern and the activation phrase, said step of confirming using a voice recognition engine available to the computing device upon full activation of the computing device. - View Dependent Claims (18)
