receiving, while the device is operating in a first power mode, first input data corresponding to first audio detected by a microphone;
determining whether the first input data represents a first sound event that is other than ambient noise;
operating, based at least in part on a determination that the first input data represents the ambient noise only, in a second power mode in which the device consumes less power than in the first power mode;
receiving, while the device is operating in the second power mode, second input data corresponding to second audio detected by the microphone;
causing, based at least in part on the second input data, the device to operate in the first power mode; and
ceasing, based at least in part on a determination that the device is executing an audio function, analysis of third input data received after the second input data.
