Claim 13:
14. A battery powered device comprising:
one or more microphones,
one or more Wi-Fi network interfaces;
one or more processors; and
memory storing instructions that, when executed, cause one or more of the processors to:
recognize speaking of a predetermined phrase in audio data received via one or more of the microphones; and
in response to recognizing the speaking of the predetermined phrase:
transmit, by the battery powered device:
a second device request that causes a second computing device, that is located in a physical environment with the battery powered device, to emit a second device audio signal via a second device speaker component of the second computing device, and
a third device request that 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; and

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