1. A computer-implemented method comprising:
- during operation of a mobile device in an awake mode providing full functionality of a voice recognition system of the mobile device;
determining, by data processing hardware of the mobile device, to operate the mobile device in a low-power mode;
in response to determining to operate the mobile device in the low-power mode and before entering the low-power mode, storing, in a frame buffer of the mobile device, a graphical user interface; and
operating, by the data processing hardware, the mobile device in the low-power mode by turning off a display of the mobile device and reducing the functionality of the voice recognition system of the mobile device; and
during operation of the mobile device in the low-power mode in which functionality of the voice recognition engine of the mobile device is reduced;
receiving, at the data processing hardware, an utterance of at least an initial portion of a predetermined command phrase, the predetermined command phrase comprising a series of multiple words configured to cause the mobile device to wake-up from the low-power mode in response to detecting each word of the series of multiple words in the utterance;
detecting, by the data processing hardware, the initial portion of the predetermined command phrase in the utterance; and
in response to detecting the initial portion of the predetermined command phrase in the utterance;
determining, by the data processing hardware, whether a remaining portion of the predetermined command phrase is detected in the utterance within a first predetermined period of time after detecting the initial portion of the predetermined command phrase in the utterance;
turning on, by the data processing hardware, the display of the mobile device; and
displaying, by the data processing hardware for output on the display, at least a portion of the graphical user interface that was stored in the frame buffer before the mobile device entered the low-power mode.

Abstract
A method include placing a first processor in a sleep operating mode and running a second processor that is operative to wake the first processor from the sleep operating mode in response to a speech command phrase. The method includes identifying, by the second processor, a speech command phrase segment and performing a control operation in response to detecting the segment in detected speech. The control operation is performed while the first processor is maintained in the sleep operating mode.
