1. A method comprising:
after receiving a voice command via a networked microphone device associated with a media playback system while one or more playback devices in the media playback system are playing audio content, selecting one playback device of the one or more playback devices of the media playback system to play an audio response to the voice command based on (i) a direction of the voice command relative to the networked microphone device and (ii) a proximity of the voice command relative to the networked microphone device;
determining a directionality for the audio response to the voice command based on the direction of the voice command relative to the networked microphone device; and
while the selected one playback device is playing the audio content at a first volume level, causing the selected one playback device to (i) reduce its volume to a second volume level lower than the first volume level and (ii) while playing the audio content at the second volume level, play the audio response according to the determined directionality for the audio response.
2. The method of claim 1 , wherein selecting one playback device of the one or more playback devices of the media playback system to play an audio response comprises causing the networked microphone device to select a determined audio response zone, and wherein playing the audio response according to the determined directionality for the audio response comprises causing the selected one playback device to play the audio response within the determined audio response zone.
3. The method of claim 1 , further comprising:
receiving, from a controller device, an indication of an audio response zone to which the networked microphone device is assigned.
4. The method of claim 1 , further comprising:
sending, to a computing device, an indication of an audio response zone to which the networked microphone device is assigned.
5. The method of claim 1 , further comprising:
applying acoustics of an environment in which the networked microphone device is placed to the received voice command.
6. The method of claim 1 , further comprising:
after receiving an indication of audio content, determining at least one music service from a plurality of music services that supports the audio content; and
causing the at least one music service to transmit the audio content to the media playback system.
7. The method of claim 1 , further comprising:
establishing a metadata exchange channel between the media playback system and the networked microphone device.
8. The method of claim 1 , wherein the media playback system comprises a fallback device, the method further comprising:
before causing the selected one playback device to play the audio response, determining that another playback device is not available to play the audio response.
9. The method of claim 1 , further comprising:
determining that the received voice command was received from a registered user of the media playback system; and
in response to determining that the received voice command was received from the registered user of the media playback system, configuring an instruction for the media playback system based on content from the voice command and information in a user profile for the registered user.
10. The method of claim 1 , wherein the received voice command comprises:
a command word, one or more media variable instances, and one or more zone variable instances.
11. A networked microphone device comprising:
one or more processors; and
tangible, non-transitory computer-readable media comprising instructions encoded therein, wherein the instructions, when executed, configure the networked microphone device to:
after receiving a voice command via a networked microphone device associated with a media playback system while one or more playback devices in the media playback system are playing audio content, select one playback device of the one or more playback devices of the media playback system to play an audio response to the voice command based on (i) a direction of the voice command relative to the networked microphone device and (ii) a proximity of the voice command relative to the networked microphone device;
determine a directionality for the audio response to the voice command based on the direction of the voice command relative to the networked microphone device; and
while the selected one playback device is playing the audio content at a first volume level, cause the selected one playback device to (i) reduce its volume to a second volume level lower than the first volume level and (ii) while playing the audio content at the second volume level, play the audio response according to the determined directionality for the audio response.
12. The networked microphone device of claim 11 , wherein the instructions that configure the networked microphone device to select one playback device of the one or more playback devices of the media playback system to play an audio response comprise instructions that, when executed by the one or more processors, configure the networked microphone device to cause the networked microphone device to select a determined audio response zone, and wherein the instructions that configure the networked microphone device to play the audio response according to the determined directionality for the audio response comprise instructions that, when executed by the one or more processors, configure the networked microphone device to cause the selected one playback device to play the audio response within the determined audio response zone.
13. The networked microphone device of claim 11 , wherein the instructions comprise further instructions that, when executed by the one or more processors, configure the networked microphone device to:
receive, via the networked microphone device from a controller device, an indication of a particular zone to which the networked microphone device is assigned.
14. The networked microphone device of claim 11 , wherein the instructions comprise further instructions that, when executed by the one or more processors, configure the networked microphone device to:
send, via the networked microphone device to a computing device, an indication of a particular zone to which the networked microphone device is assigned.
15. The networked microphone device of claim 11 , wherein the instructions comprise further instructions that, when executed by the one or more processors, configure the networked microphone device to:
apply acoustics of an environment in which the networked microphone device is placed to the received voice command.
16. The networked microphone device of claim 11 , wherein the instructions comprise further instructions that, when executed by the one or more processors, configure the networked microphone device to:
after receiving an indication of audio content, determine at least one music service from a plurality of music services that supports the audio content; and
cause the at least one music service to transmit the audio content to the media playback system.
17. The networked microphone device of claim 11 , wherein the instructions comprise further instructions that, when executed by the one or more processors, configure the networked microphone device to:
establish a metadata exchange channel between the media playback system and the networked microphone device.
18. The networked microphone device of claim 11 , wherein the selected one playback device comprises a fallback device, and wherein the instructions comprise further instructions that, when executed by the one or more processors, configure the networked microphone device to:
before causing the selected one playback device to play the audio response, determine that another playback device is not available to play the audio response.
19. The networked microphone device of claim 11 , wherein the instructions comprise further instructions that, when executed by the one or more processors, configure the networked microphone device to:
determine that the received voice command was received from a registered user of the media playback system; and
in response to determining that the received voice command was received from the registered user of the media playback system, configure an instruction for the media playback system based on content from the voice command and information in a user profile for the registered user.
20. The networked microphone device of claim 11 , wherein the received voice command comprises:
