Claim 20:
21. A method implemented by one or more processors of a first computing device, the method comprising:
recognizing speaking of a predetermined phrase in audio data received via one or more microphones of the first computing device;
in response to recognizing the speaking of the predetermined phrase:
transmitting a request that:
causes a second computing device, that is located in a physical environment with the first computing device, to emit a second device audio signal via a second device speaker component of the second computing device, and
causes a third computing device, that is also located in the physical environment, to emit a third device audio signal via a third device speaker component of the third computing device,
wherein the second device audio signal and the third device audio signal are each above a range of human hearing;

detecting, via one or more of the microphones of the battery powered device, the second device audio signal and the third device audio signal;
determining, based on at least (i) the second device audio signal as detected via one or more of the microphones and (ii) the third device audio signal as detected via one or more of the microphones, that the second computing device is most proximal to the first computing device; and
in response to determining that the second computing device is most proximal to the first computing device:
cause the second computing device to provide audible output.
