Abstract

Multiple aspects of systems and methods for voice control and related features and functionality for various embodiments of media playback devices, networked microphone devices, microphone-equipped media playback devices, and speaker-equipped networked microphone devices are disclosed and described herein, including but not limited to designating and managing default networked devices, audio response playback, room-corrected voice detection, content mixing, music service selection, metadata exchange between networked playback systems and networked microphone systems, handling loss of pairing between networked devices, actions based on user identification, and other voice control of networked devices.

Claims

1. A method, comprising:

receiving, via a networked microphone device associated with a media playback system, a voice command, wherein the media playback system comprises one or more zones;

determining, via the networked microphone device, an audio response zone that is closest to a user, wherein the determined audio response zone comprises one or more playback devices;

selecting, via the networked microphone device, the determined audio response zone to play the audio response; and

causing, via the networked microphone device, at least one playback device of the one or more playback devices of the selected audio response zone to play the audio response.

2. The method of claim 1, wherein

determining, via the networked microphone device, the audio response zone comprises causing, via the networked microphone device, a computing device to determine the audio response zone, and wherein

selecting, via the networked microphone device, the determined audio response zone comprises causing, via the networked microphone device, the computing device to select the determined audio response zone, and wherein

causing, via the networked microphone device, at least one playback device of the one or more playback devices of the selected audio response zone to play the audio response comprises causing, via the networked microphone device and the computing device, the at least one playback device of the one or more playback devices of the selected audio response zone to play the audio response.

3. The method of claim 1, further comprising:

receiving, via the networked microphone device from a controller device, an indication of a particular zone to which the networked microphone device is assigned.

4. The method of claim 1, further comprising:

sending, via the networked microphone device to the computing device, an indication of a particular zone to which the networked microphone device is assigned.

5. The method of claim 1, further comprising:

applying, via the networked microphone device, 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:

causing, via the networked microphone device, the at least one playback device to adjust a volume of audio content to a volume level that is below a volume level of the audio response.

7. The method of claim 1, further comprising:

receiving, via the networked microphone device, an indication of audio content;

determining, via the networked microphone device, at least one music service from a plurality of music services that supports the audio content; and

causing, via the networked microphone device, the at least one music service to transmit the audio content to the at least one playback device.

8. The method of claim 1, further comprising:

establishing, via the networked microphone device, a metadata exchange channel between the media playback system and the networked microphone device.

9. The method of claim 1, wherein the at least one playback device comprises a fallback device, the method further comprising:

before causing the at least one playback device to play the audio response, determining, via the networked microphone device, that another playback device is not available to play the audio response.

10. The method of claim 1, further comprising:

determining, via the networked microphone device, 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, via the networked microphone device, an instruction for the media playback system based on content from the voice command and information in a user profile for the registered user.

11. 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.
