Abstract

A storage machine holds instructions executable by a logic machine to receive a digital representation of a spoken command. The digital representation is provided to a speech recognizer trained with a user-specific grammar library. The logic machine then receives from the speech recognizer a confidence rating for each of a plurality of different media items. The confidence rating indicates the likelihood that the media item is named in the spoken command. The logic machine then automatically plays back the media item with a greatest confidence rating.

Claims

1. A storage machine holding instructions executable by a logic machine to:

receive a digital representation of a spoken command;

provide the digital representation to a speech recognizer trained with a user-specific grammar library;

receive from the speech recognizer a confidence rating for each of a plurality of different media items, the confidence rating indicating a likelihood that the media item is named in the spoken command; and

automatically playback the media item with a greatest confidence rating.

2. The storage machine of claim 1, wherein the user-specific grammar library includes item identifiers for a plurality of media items in a user'"'"'s media library.

3. The storage machine of claim 2, wherein the user-specific grammar library further includes parent container identifiers for a plurality of parent containers comprising the plurality of media items in a user'"'"'s media library.

4. The storage machine of claim 3, further holding instructions executable by a logic machine to:

automatically playback a plurality of media items included in a parent container if the parent container has a confidence rating greater than or equal to the greatest confidence rating of an individual media item.

5. The storage machine of claim 3, wherein the user-specific grammar library includes item identifiers and parent container identifiers for media items found in media libraries belonging to members of a user'"'"'s social graph.

6. The storage machine of claim 5, wherein the user-specific grammar library includes item identifiers and parent container identifiers for media items trending outside of the user'"'"'s social graph on an online social network.

7. The storage machine of claim 6, wherein the user-specific grammar library includes item identifiers and parent container identifiers for media items related to a user'"'"'s computer usage history and/or a user'"'"'s online network usage history.

8. The storage machine of claim 1, further holding instructions that, when executed by the logic machine, cause the logic machine to:

automatically playback the media item with the greatest confidence rating only when the greatest confidence rating is larger than a threshold.

9. The storage machine of claim 8, further holding instructions that, when executed by the logic machine, cause the logic machine to:

indicate to a user a plurality of media items with confidence ratings closest to the threshold if no individual media item has a confidence rating larger than the threshold;

receive user input selecting one of the plurality of media items with confidence ratings closest to the threshold for playback; and

playback the selected media item.

10. The storage machine of claim 1, further holding instructions that, when executed by the logic machine, cause the logic machine to:

indicate to the user that a media item with a greatest confidence rating is queued for playback; and

automatically playback the media item with the greatest confidence rating following a queuing time interval.

11. A computer system, comprising:

a logic machine; and

a storage machine holding instructions that, when executed by the logic machine, cause the logic machine to;

receive a digital representation of a user command;

determine a confidence rating for a plurality of different media items, the confidence rating indicating a likelihood that the media item is named in the user command;

indicate to a user that a media item with a greatest confidence rating is queued for playback; and

cancel playback of the media item with the greatest confidence rating responsive to user input; and

indicate to the user a plurality of media items with the next greatest confidence ratings.

12. The computer system of claim 11, where the plurality of different media items includes media items in a user'"'"'s media library.

13. The computer system of claim 12, further comprising a communications system in communication with a media server, and wherein the plurality of different media items further includes media items accessible via the media server.

14. The computer system of claim 13, wherein determining the confidence rating for a media item includes weighting media items in the user'"'"'s media library more than media items accessible via the media server.

15. The computer system of claim 11, wherein the plurality of media items with the next greatest confidence ratings does not include the media item with the greatest confidence rating.

16. The computer system of claim 13, wherein the plurality of media items with the next greatest confidence ratings does not include more than one copy of a media item.

17. The computer system of claim 11, where the storage machine further holds instructions that, when executed by the logic machine, cause the logic machine to:

interpret spoken commands of the user as input indicating not to playback the media item with the greatest confidence rating.

18. The computer system of claim 11, where the storage machine further holds instructions that, when executed by the logic machine, cause the logic machine to:

interpret gesture commands of the user as input indicating not to playback the media item with the greatest confidence rating.

19. A computer system including a logic machine, and a storage machine holding instructions that, when executed by the logic machine, cause the logic machine to:

receive a digital representation of a spoken command;

provide the digital representation to a speech recognizer trained with a user-specific grammar library;

receive from the speech recognizer a confidence rating for each of a plurality of different media items, the confidence rating indicating a likelihood that the media item is named in the spoken command;

indicate to the user that a media item with a greatest confidence rating is queued for playback;

automatically playback the media item with the greatest confidence rating following a queuing time interval;

cancel playback of the media item with the greatest confidence rating responsive to user input prior to expiration of the queuing time interval;

indicate to the user a plurality of different media items with the next greatest confidence ratings;

receive user input selecting one of the plurality of media items with the next greatest confidence ratings for playback; and

playback the selected media item.

20. The computer system of claim 19, wherein the user-specific grammar library includes a plurality of item identifiers for a plurality of media items available for playback, and further includes a plurality of parent container identifiers for a plurality of parent containers comprising the plurality of media items available for playback.
