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.

First claim

We claim:

1. A system comprising:
at least one processor;
at least one microphone;
at least one non-transitory computer-readable medium; and
program instructions stored on the at least one non-transitory computer-readable medium that are executable by the at least one processor such that the system is configured to:
cause a first playback device to play back a media item;
while the first playback device is playing back the media item:
capture, via the at least one microphone, a first voice input comprising (i) a first command word and (ii) a first one or more zone variable instances; and
determine, based on the first command word and the first one or more zone variable instances, a command to transfer playback of the media item to a second playback device;

after determining the command to transfer playback of the media item to the second playback device, cause playback of the media item to be transferred to the second playback device such that the first playback device continues playing back the media item and coordinates with the second playback device to begin playing back the media item in synchrony with the second playback device;
while the first playback device is playing back the media item in synchrony with the second playback device:
capture, via the at least one microphone, a second voice input comprising (i) a second command word and (ii) a second one or more zone variable instances; and
determine, based on the second command word and the second one or more zone variable instances, a command to ungroup the first playback device from the second playback device; and

after determining the command to ungroup the first playback device from the second playback device, cause the first playback device to be ungrouped from the second playback device such that the first playback device discontinues playing back the media item and the second playback device continues playing back the media item.

2. The system of claim 1 , wherein the media item is identified in a playback queue.

3. The system of claim 2 , wherein at least a portion of the playback queue is stored on a remote computing device associated with a cloud-based computing system.

4. The system of claim 2 , wherein the determined command to transfer playback of the media item to the second playback device comprises a command for the second playback device to assume playback responsibility for the playback queue.

5. The system of claim 1 , wherein the first command word is associated with a media playback system command to transfer playback of the media item, at a current playback position, to one or more other playback devices, and wherein the program instructions that are executable by the at least one processor such that the system is configured to cause playback of the media item to be transferred to the second playback device comprise program instructions that are executable by the at least one processor such that the system is configured to cause playback of the media item to be transferred to the second playback device such that the first playback device continues playing back the media item and coordinates with the second playback device to begin playing back the media item in synchrony with the second playback device at the current playback position.

6. The system of claim 1 , wherein the first one or more zone variable instances corresponds to a playback zone that includes at least two playback devices, and wherein the program instructions that are executable by the at least one processor such that the system is configured to cause playback of the media item to be transferred to the second playback device comprise program instructions that are executable by the at least one processor such that the system is configured to cause playback of the media item to be transferred to the playback zone such that the first playback device continues playing back the media item and coordinates with one or more playback devices in the playback zone to begin playing back the media item in synchrony with each playback device in the playback zone.

7. The system of claim 1 , wherein the program instructions that are executable by the at least one processor such that the system is configured to determine, based on the first command word and the first one or more zone variable instances, the command to transfer playback of the media item to the second playback device comprise program instructions that are executable by the at least one processor such that the system is configured to:
convert the captured first voice input from speech to text; and
parse the text to identify the command to transfer playback of the media item to the second playback device.

8. The system of claim 1 , wherein the program instructions that are executable by the at least one processor such that the system is configured to cause playback of the media item to be transferred to the second playback device such that the first playback device coordinates with the second playback device such that the second playback device begins playing back the media item in synchrony with the first playback device comprise program instructions that are executable by the at least one processor such that the first playback device is configured to transmit (i) audio information corresponding to the media item and (ii) playback timing information to the second playback device.

9. The system of claim 1 , wherein the program instructions that are executable by the at least one processor such that the system is configured to cause playback of the media item to be transferred to the second playback device such that the first playback device coordinates with the second playback device such that the second playback device begins playing back the media item in synchrony with the first playback device comprise program instructions that are executable by the at least one processor such that the first playback device is configured to receive, from the second playback device, (i) audio information corresponding to the media item and (ii) playback timing information.

10. The system of claim 1 , wherein the program instructions that are executable by the at least one processor such that the system is configured to cause playback of the media item to be transferred to the second playback device comprise program instructions that are executable by the at least one processor such that system is configured to cause the second playback device to receive an instruction from at least one of the first playback device or a remote computing device, thereby causing the second playback device to play back the media item.

11. The system of claim 1 , wherein one of the first playback device and the second playback device comprises the at least one processor, the at least one microphone, and the at least one non-transitory computer-readable medium.

12. The system of claim 1 , further comprising a third playback device, wherein the third playback device comprises the at least one processor, the at least one microphone, and the at least one non-transitory computer-readable medium.

13. The system of claim 1 , further comprising program instructions stored on the at least one non-transitory computer-readable medium that are executable by the at least one processor such that the system is configured to:
capture, via the at least one microphone, a third voice input comprising (i) a third command word and (ii) a third one or more zone variable instances; and
determine, based on the third command word and the third one or more zone variable instances, a command to begin playback of the media item via the first playback device in a standalone playback mode, wherein the program instructions
