Abstract: An example system is configured to cause a first playback device in a first playback zone to operate in a given playback state including play back of media items identified in a playback queue associated with the first playback zone. The system is also configured to, while the first playback device is operating in the given playback state, (i) receive data corresponding to a detected voice input including an indication of (a) a command word and (b) one or more zone variable instances and (ii) determine, based on the command word and the one or more zone variable instances, an intent to transfer the given playback state to a second playback zone. The system is also configured to transfer the given playback state to the second playback zone, thereby causing a second playback device in the second playback zone to play back the media items identified in the playback queue.

Abstract: A voice input comprising a command word, one or more media variable instances, and one or more zone variable instances is received. A media playback system command which corresponds to the command word is determined. Media content which corresponds to the one or more media variable instances is identified. The media playback system is caused to execute the media playback system command on the media content based on the one or more zone variable instances.

Abstract: Systems and methods disclosed herein include (i) receiving a voice command via a networked microphone device configured to receive voice commands for a media playback system, wherein the media playback system comprises a primary media playback device configured to perform a function and/or provide a first feedback in response to voice commands received via the networked microphone device, (ii) determining that the primary media playback device is not available to perform a function and/or provide the first feedback in response to the voice command, and (iii) in response to determining that the primary media playback device is not available to perform a function and/or provide the first feedback in response to the voice command, instructing a fallback device to perform a function and/or provide a second feedback in response to the voice command.

Abstract: 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.
