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 an idle mode, the mobile device having a first processor and a second processor, the method comprising:
- receiving acoustic input while the mobile device is operating in the idle mode;
performing at least one first processing stage on the acoustic input using the first processor, prior to engaging the second processor to process the acoustic input, to evaluate whether the acoustic input includes a voice command;
performing at least one second processing stage on the acoustic input using the second processor to evaluate whether the acoustic input includes a voice command if further processing is needed to determine whether the acoustic input includes a voice command;
wherein performing the at least one first processing stage or the at least one second processing stage includes, while the mobile device is operating in the idle mode, transmitting at least a portion of the acoustic input to at least one server via a network for processing by the at least one server at least to evaluate whether the acoustic input includes a voice command; and
initiating responding to the voice command when either the at least one first processing stage or the at least one second processing stage determines that the acoustic input includes a voice command.

Abstract
Some aspects include a method of monitoring an acoustic environment of a mobile device operating in a low power mode, the mobile device having a first and second processor, the method comprises receiving acoustic input while the mobile device is operating in the low power mode, performing at least one first processing stage on the acoustic input using the first processor, prior to engaging the second processor, to evaluate whether the acoustic input includes a voice command, performing at least one second processing stage on the acoustic input using the second processor to evaluate whether the acoustic input includes a voice command if further processing is needed to determine whether the acoustic input includes a voice command, and initiating responding to the voice command when either the at least one first processing stage or the at least one second processing stage determines that the acoustic input includes a voice command.

14. A mobile device comprising:
-
at least one input to receive acoustic input from an environment of the mobile device while the mobile device is operating in an idle mode; a first processor to perform at least one first processing stage on the acoustic input to evaluate whether the acoustic input includes a voice command; a second processor to perform at least one second processing stage on the acoustic input to evaluate whether the acoustic input includes a voice command, and wherein the mobile device is configured to provide, prior to waking up the mobile device, at least one indication to the user to confirm that the acoustic input was received and is being processed, wherein the at least one first processing stage is performed prior to engaging the second processor, wherein the at least one second processing stage is performed if further processing is needed to determine whether the acoustic input includes a voice command, and wherein response to the voice command is initiated when either the at least one first processing stage or the at least one second processing stage determines that the acoustic input includes a voice command. - View Dependent Claims (15, 16, 17)
