1. A network microphone device (NMD) comprising:
one or more processors;
one or more microphones; and
data storage having instructions thereon that, when executed by the one or more processors, cause the NMD to perform operations comprising:
detecting sound via the one or more microphones;
capturing sound data based on the detected sound, wherein the sound data includes a voice input;
analyzing the sound data to detect a wake word;
capturing metadata associated with the sound data, wherein the voice input is not derivable from the metadata;
obtaining an intent based on the voice input;
performing a command based on the intent; and
based on the metadata, modifying at least one performance parameter of the NMD.
