Abstract

A system and method for voice control of a media playback device is disclosed. The method includes receiving an instruction of a voice command, converting the voice command to text, transmitting the text command to the playback device, and having the playback device execute the command. An instruction may include a command to play a set of audio tracks, and the media playback device plays the set of audio tracks upon receiving the instruction.

First claim

What is claimed is:

1. A method for playing a media content item via a voice command, the method comprising:
receiving an audio clip of an instruction, the instruction comprising:
an activation trigger portion identifying a wake signal,
a command portion identifying intent information, and
a parameter portion identifying a shortcut;

identifying the instruction by converting the audio clip to a text version and determining the intent information and the shortcut from the text version;
identifying a plurality of media content items associated with the shortcut;
associating the shortcut with a physical button located on a media playback device;
transmitting the media content items to the media playback device for playback;
obtaining a second audio clip of a save instruction during playback of the media content items, the save instruction having a second command portion and a second parameter portion identifying a shortcut alias, and the second command portion including a save request;
identifying the save instruction by converting the second audio clip to a second text version and determining the second command portion and the shortcut alias from the second text version; and
associating the plurality of media content items with the shortcut alias of the media playback device; and
associating the shortcut alias with the physical button located on the medial playback device.

2. The method according to claim 1 , further comprising:
prior to identifying the media content item,
transmitting the shortcut to the media playback device; and
receiving a shortcut signal from the shortcut of the media playback device,

wherein the media content item is identified based on the received shortcut.

3. The method according to claim 1 , wherein the second parameter portion of the save instruction includes a shortcut number predetermined for the second shortcut alias.

4. The method according to claim 1 , wherein the second parameter portion of the save instruction includes a set of one or more words given by a user who provides the save instruction.

5. The method according to claim 1 , wherein the save shortcut command portion includes a set of one or more words automatically generated by at least one computing device.

6. The method according to claim 1 , wherein when the instruction does not comprise the wake signal, the command portion and the parameter portion are not converted to a text version.

7. The method according to claim 1 , wherein the save instruction further comprises an activation trigger portion, the activation portion identifying a wake phrase.

8. The method according to claim 7 , wherein when the save instruction does not comprise the wake signal, the save shortcut command is not converted to a text version.

9. A system for operating a voice command interface configured to control a media playback device, the system comprising:
a speech recognition engine configured to:
receive an audio clip of an instruction, the instruction comprising:
an activation trigger portion identifying a wake signal,
a command portion identifying intent information, and
the parameter portion identifying a shortcut; and

a speech analysis engine configured to:
identify the instruction by converting the audio clip to a text version and determining the intent information and the shortcut from the text version;
identify a plurality of media content items associated with the shortcut;
associate the shortcut with a physical button located on a media playback device;
transmit the media content items to the media playback device to perform the command;
obtain a second audio clip of a save instruction during playback of the media content items, the save instruction having a second command portion and a second parameter portion identifying a shortcut alias, and the second command portion including a save request;
identify the save instruction by converting the second audio clip to a second text version and determining the second command portion and the shortcut alias from the second text version; and
associate the plurality of media content items with the shortcut alias of the media playback device; and
associate the shortcut alias with the physical button located on the medial playback device.

10. The system according to claim 9 , wherein the second command portion includes a shortcut number predetermined for the shortcut alias.

11. The system according to claim 9 , wherein the second command portion includes a set of one or more words given by a user who provides the save instruction.

12. The system according to claim 9 , wherein the second command portion includes a set of one or more words automatically generated by at least one computing device.

13. The system according to claim 9 , wherein the save instruction further comprises an activation trigger portion, the activation portion identifying a wake phrase.

14. The system according to claim 13 , wherein when the save instruction does not comprise the wake signal, the save shortcut command is not converted to a text version.

15. The system according to claim 9 , wherein when the instruction does not comprise the wake signal, the command portion and the parameter portion are not converted to a text version.
