This is directed to processing voice inputs received by an electronic device. In particular, this is directed to receiving a voice input and identifying the user providing the voice input. The voice input can be processed using a subset of words from a library used to identify the words or phrases of the voice input. The particular subset can be selected such that voice inputs provided by the user are more likely to include words from the subset. The subset of the library can be selected using any suitable approach, including for example based on the user's interests and words that relate to those interests. For example, the subset can include one or more words related to media items selected by the user for storage on the electronic device, names of the user's contacts, applications or processes used by the user, or any other words relating to the user's interactions with the device.

1. A method for processing a voice input, comprising: at an electronic device with one or more processors and memory storing one or more programs for execution by the one or more processors: receiving a voice input;identifying a user providing the voice input;identifying a subset of library words associated with the identified user, wherein the subset of library words relates to user interest information that is based on words or phrases from previously received voice inputs; andprocessing the received voice input using the identified subset. 2. The method of claim 1, further comprising: identifying an electronic device operation corresponding to the processed voice input. 3. The method of claim 1, further comprising: retrieving at least one instruction from the processed voice input; andidentifying at least one electronic device operation corresponding to the retrieved at least one instruction. 4. The method of claim 3, wherein: the at least one instruction comprises an operation and an argument qualifying the operation. 5. The method of claim 4, wherein: the operation comprises a media playback operation; andthe argument comprises a particular media item. 6. The method of claim 5, wherein processing further comprises: detecting a plurality of words in the received voice input;comparing the detected plurality of words with the identified subset of library words; andidentifying a plurality of words from the identified subset that correspond to the detected plurality of words. 7. The method of claim 6, further comprising: extracting an instruction for the identified plurality of words; andidentifying an operation corresponding to the extracted instruction. 8. The method of claim 1, wherein identifying the user further comprises: extracting a voice print from the received voice input;comparing the extracted voice print with a library of known voice prints; andidentifying the user having a voice print in the library of known voice prints that corresponds to the received voice print. 9. The method of claim 1, wherein the words or phrases are determined to be properly identified when a device operation corresponding to the words or phrases is approved by the user. 10. An electronic device controllable by voice inputs, comprising a processor, an input interface, and an output interface, the processor operative to: direct the input interface to receive a voice input from a user;identify the user providing the received voice input;provide the identity of the user to a library of words used to process voice inputs;receive a subset of the library of words, wherein the subset includes words likely to be used by the identified user, and wherein the subset of library words relates to user interest information that is based on words or phrases from previously received voice inputs that were determined to be properly identified;process the voice input using the received subset; anddirect the output interface to provide an output based on the processed voice input. 11. The electronic device of claim 10, wherein the processor is further operative to: direct the output interface to play back a media item. 12. The electronic device of claim 11, wherein the processor is further operative to: identify a media playback operation from the voice input; andidentify a media item qualifying the media playback operation from the voice input. 13. The electronic device of claim 10, wherein the processor is further operative to identify the user from at least one of: the content of the voice input;the time at which the voice input was provided; andthe voice signature of the voice print. 14. The electronic device of claim 10, wherein: the subset of media item words includes words corresponding to metadata values of content selected by the user for storage on the electronic device. 15. The electronic device of claim 14, wherein the content selected by the user for storage on the electronic device comprises at least one of: media items;contact information;applications;calendar information; andsettings. 16. A method for defining a subset of a library used for processing voice inputs, comprising: at an electronic device with one or more processors and memory storing one or more programs for execution by the one or more processors:providing a library of words from which to process voice inputs;identifying user interest information by identifying words or phrases from previously received voice inputs that were determined to be properly identified;extracting, from the user interest information, words that the user is likely to use to provide a voice input; anddefining a subset of the library, wherein the subset comprises at least the words of the library matching the extracted words. 17. The method of claim 16, further comprising: identifying particular media items of interest to the user; andincluding metadata values for the identified particular media items in the defined subset. 18. The method of claim 17, wherein the metadata values comprise at least one of: artist;title;album;genre;year;play count;rating; andplaylist. 19. The method of claim 16, further comprising: comparing the extracted words to the words of the library;identifying words of the library that share at least a common root with at least one extracted word; andincluding the identified words of the library in the defined subset. 20. The electronic device of claim 10, wherein the words or phrases are determined to be properly identified when a device operation corresponding to the words or phrases is approved by the user. 21.
