METHODS AND APPARATUS FOR DETECTING A VOICE COMMAND
First Claim
1. A method of monitoring an acoustic environment of a mobile device for voice commands when the mobile device is operating in a low power mode, the method comprising:
- receiving acoustic input from the environment of the mobile device while the mobile device is operating in the low power mode;
detecting whether the acoustic input includes a voice command based on performing a plurality of processing stages on the acoustic input, wherein at least one of the plurality of processing stages is performed while the mobile device is operating in the low power mode; and
using at least one contextual cue to assist in detecting whether the acoustic input includes a voice command.

19. At least one computer readable medium encoded with instructions that, when executed on at least one processor, perform a method of monitoring an acoustic environment of a mobile device to receive acoustic input from the environment of the mobile device while the mobile device is operating in a low power mode, the method comprising:
-
detecting whether the acoustic input includes a voice command based on performing a plurality of processing stages on the acoustic input, wherein at least one of the plurality of processing stages is performed while the mobile device is operating in the low power mode; and using at least one contextual cue to assist in detecting whether the acoustic input includes a voice command.
