Claim 0:
1. 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;
in response to recognizing the speaking of the predetermined phrase:
transmit a 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
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;

detect, at the battery powered device and via one or more of the microphones of the battery powered device, the second device audio signal and the third device audio signal;
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.
