First Claim
Patent Images
1. A computer-implemented method comprising:
- during operation of a mobile computing device in a low power mode in which functionality of a voice recognition engine of the mobile computing device is reduced;
receiving, at data processing hardware of the mobile computing device, 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 computing 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;
activating, by the data processing hardware, a display of the mobile computing device;
providing, by the data processing hardware for output on the display, display data that was stored in a frame buffer of the mobile computing device before receiving the utterance of at least the initial portion of the predetermined command phrase; and
when the remaining portion of the predetermined command phrase is not detected in the utterance within the first predetermined period of time, automatically deactivating, by the data processing hardware, the display of the mobile device a second predetermined period of time after providing the display data for output on the display.

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.

15. A non-transitory computer-readable medium storing software comprising instructions executable by one or more computers which, upon such execution, cause the one or more computers to perform operations comprising:
-
during operation of a mobile computing device in a low power mode in which functionality of a voice recognition engine of the mobile computing device is reduced; receiving 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 computing device to wake-up from the low power mode in response to detecting each word of the series of multiple words in the; detecting 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 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; activating a display of the mobile computing device; providing, for output on the display, display data that was stored in a frame buffer of the mobile computing device before receiving the utterance of at least the initial portion of the predetermined command phrase; and when the remaining portion of the predetermined command phrase is not detected in the utterance within the first predetermined period of time, automatically deactivating the the display of the mobile device a second predetermined period of time after providing the display data for output on the display. - View Dependent Claims (16, 17, 18, 19, 20)
