Disclosed herein are systems and methods for establishing a metadata exchange channel between a media playback system and a networked microphone system, wherein the networked microphone system comprises a networked microphone device and a networked microphone server. After establishing the metadata exchange channel, the media playback system experiences a metadata exchange triggering event. In response to experiencing the metadata exchange triggering event, the media playback system provides metadata to the networked microphone system via the metadata exchange channel.
