Abstract

Embodiments of the present invention improve content selection systems and methods using speech recognition. In one embodiment, the present invention includes a speech recognition method comprising storing content on an electronic device, wherein the content is associated with a plurality of content attribute values, adding the content attribute values to a first recognition set of a speech recognizer, receiving a speech input signal in said speech recognizer, generating a plurality of likelihood values in response to the speech input signal, wherein each likelihood value is associated with one content attribute value in the recognition set; and accessing the stored content based on the likelihood values.

Claims

1. A speech recognition method comprising:

storing content on an electronic device, wherein the content is associated with a plurality of content attribute values;

adding the content attribute values to a first recognition set of a speech recognizer;

receiving a speech input signal in said speech recognizer;

generating a plurality of likelihood values in response to the speech input signal, wherein each likelihood value is associated with one content attribute value in the recognition set; and

accessing the stored content based on the likelihood values.

2. The method of claim 1 further comprising ranking the likelihood values, wherein the stored content is accessed based on said ranking.

3. The method of claim 2 wherein the ranking is highest likelihood to the lowest likelihood.

4. The method of claim 1 further comprising generating a play list based on the likelihood values.

5. The method of claim 1 wherein the content is further associated with attributes, and wherein said attributes are added to a second recognition set, and wherein the first recognition set comprises a plurality of attribute recognition sets each including a plurality of content attribute values associated with a particular attribute, wherein generating the plurality of likelihood values comprises:

recognizing an attribute from a first spoke utterance in said speech input signal using the second recognition set;

selecting one of the attribute recognition sets based on the recognized attribute; and

recognizing a content attribute value from a second spoken utterance in said speech input signal using the selected attribute recognition set.

6. The method of claim 5 further comprising a command recognition set including a plurality of commands, wherein if a spoken utterance in said speech input signal includes one or more commands in the command recognition set, then said commands are executed by the electronic device.

7. The method of claim 1 wherein the content comprises content data and content metadata, and wherein the content metadata comprises said content attribute values.

8. The method of claim 1 wherein the content attribute values comprise a song title or a name of an artist.

9. The method of claim 1 wherein the content is digital music.

10. The method of claim 1 wherein the content is digital video.

11. The method of claim 1 wherein the content is a digital recording.

12. The method of claim 1 wherein the content is stored in a database.

13. The method of claim 1 wherein the electronic device is a portable music player, a portable phone, a portable digital assistant, or a portable video player.

14. A speech recognition method comprising:

storing content on an electronic device, wherein the content is associated with a plurality of content attributes and a plurality of content attribute values;

adding at least one content attribute to a content attribute recognition set;

adding the plurality of content attribute values to a plurality of content attribute value recognition sets wherein each content attribute value recognition set is associated with at least one content attribute;

receiving a speech input signal including multiple spoken utterances;

recognizing an utterance from the multiple spoken utterances as a content attribute using the content attribute recognition set;

selecting one of the content attribute value recognition sets based on the recognized content attribute;

generating a plurality of likelihood values in response to a subsequent utterance from the multiple spoken utterances, wherein each likelihood value is associated with one content attribute value in the selected content attribute value recognition set; and

accessing the stored content based on the likelihood values.

15. The method of claim 14 further comprising ranking the likelihood values, wherein the stored content is accessed based on said ranking.

16. The method of claim 14 further comprising a command recognition set wherein player commands are added to the command recognition set and used to recognize commands.

17. The method of claim 14 further comprising multiple recognitions of a plurality of content attributes and a plurality of content attribute values from the multiple spoken utterances and weighting each of the corresponding likelihood values based on the order of the content attributes or attribute values recognized from the multiple spoken utterances.

18. The method of claim 17 further comprising generating a play list based on the weighted likelihood values.

19. The method of claim 14 wherein the content is stored in a database.

20. The method of claim 14 wherein the electronic device is a portable music player, a portable phone, a portable digital assistant, or a portable video player.
