Claim 0:
1. A first networked microphone device comprising:
a network interface;
at least one microphone;
at least one processor;
a wake-word engine configured to receive as input sound data via the at least one microphone;
a non-transitory computer-readable medium; and
program instructions stored on the non-transitory computer-readable medium that are executable by the at least one processor such that the first networked microphone device is configured to:
receive, via the at least one microphone, sound data;
determine, via the wake-word engine, that at least a first portion of the sound data is representative of a wake word;
determine that a second networked microphone device is available for processing of received sound data, wherein the first networked microphone device and the second networked microphone device are connected via a local data network;
based on determining that the first portion of the sound data is representative of the wake word and that the second networked microphone device is available for processing of received sound data, transmit, via the network interface, the first portion of the sound data to the second networked microphone device;
begin determining a command, based on at least a second portion of the sound data, to be performed by the first networked microphone device; and
receive, from the second networked microphone device, an indication of whether the first portion of the sound data is representative of the wake word.
