Abstract

A speech recognition system uses, in one embodiment, an extended phonetic dictionary that is obtained by processing words in a user'"'"'s set of databases, such as a user'"'"'s contacts database, with a set of pronunciation guessers. The speech recognition system can use a conventional phonetic dictionary and the extended phonetic dictionary to recognize speech inputs that are user requests to use the contacts database, for example, to make a phone call, etc. The extended phonetic dictionary can be updated in response to changes in the contacts database, and the set of pronunciation guessers can include pronunciation guessers for a plurality of locales, each locale having its own pronunciation guesser.

Claims

1. A machine readable non-transitory storage medium storing executable instructions which, when executed by a data processing system, cause the data processing system to perform a method comprising:

storing a phonetic dictionary for speech recognition;

obtaining words from a user'"'"'s set of one or more databases;

processing, using a set of one or more pronunciation guessers, the words from the user'"'"'s set of one or more databases, the processing producing additional phonetic data derived from the words, the additional phonetic data forming an extended phonetic dictionary for the user;

receiving a speech input;

processing the speech input by comparing phonemes detected in the speech input to the phonetic dictionary and to the extended phonetic dictionary to determine a set of one or more matches;

determining a best match from the set of one or more matches.

2. The medium as in claim 1 wherein the user'"'"'s set of one or more databases comprises a contacts database with names of people and telephone numbers, and wherein the phonetic dictionary is for natural language speech recognition and wherein the speech input is for calling a telephone number or sending a text message to another user'"'"'s device.

3. The medium as in claim 2, wherein the method further comprises:

obtaining changes in the contacts database and processing, using the set of one or more pronunciation guessers, the changes to update the extended phonetic dictionary based on the changes, wherein the obtaining of the changes occurs in response to the changes being made.

4. The medium as in claim 3, wherein the set of one or more pronunciation guessers comprise pronunciation guessers for a plurality of locales, each locale having its own pronunciation guesser.

5. The medium as in claim 3, wherein the set of one or more pronunciation guessers comprises different pronunciation guessers for the same locale.

6. The medium as in claim 4, wherein the method further comprises:

determining automatically a set of languages or locales from the words in the user'"'"'s set of one or more databases;

selecting a subset of the set of one or more pronunciation guessers, the subset selected based upon the set of languages or locales that were automatically determined from the words in the user'"'"'s set of one or more databases; and

wherein the processing which produces the additional phonetic data uses only the subset of the set of one or more pronunciation guessers when producing the additional phonetic data.

7. The medium as in claim 4 wherein the method is performed by a server that is coupled through a wireless network to the user'"'"'s device which includes the contacts database and wherein the server obtains the words in the contacts database from the user'"'"'s device through the wireless network and wherein the server receives the speech input from the user'"'"'s device through the wireless network and wherein the server transmits the best match to the user'"'"'s device through the wireless network.

8. The medium as in claim 3 wherein the method is performed by the user'"'"'s device which includes the contacts database.

9. The medium as in claim 7 wherein the server performs the method for a plurality of users, and each user in the plurality of users has a dedicated extended phonetic dictionary that is unique to each user.

10. A machine implemented method comprising:

storing a phonetic dictionary for speech recognition;

obtaining words from a user'"'"'s set of one or more databases;

processing, using a set of one or more pronunciation guessers, the words from the user'"'"'s set of one or more databases, the processing producing additional phonetic data derived from the words, the additional phonetic data forming an extended phonetic dictionary for the user;

receiving a speech input;

processing the speech input by comparing phonemes detected in the speech input to the phonetic dictionary and to the extended phonetic dictionary to determine a set of one or more matches;

determining a best match from the set of one or more matches.

11. The method as in claim 10 wherein the user'"'"'s set of one or more databases comprises a contacts database with names of people and telephone numbers, and wherein the phonetic dictionary is for natural language speech recognition and wherein the speech input is for calling a telephone number or sending a text message to another user'"'"'s device.

12. The method as in claim 11, wherein the method further comprises:

obtaining changes in the contacts database and processing, using the set of one or more pronunciation guessers, the changes to update the extended phonetic dictionary based on the changes, wherein the obtaining of the changes occurs in response to the changes being made.

13. The method as in claim 12, wherein the set of one or more pronunciation guessers comprise pronunciation guessers for a plurality of locales, each locale having its own pronunciation guesser.

14. The method as in claim 12, wherein the set of one or more pronunciation guessers comprises different pronunciation guessers for the same locale.

15. The method as in claim 13, wherein the method further comprises:

determining automatically a set of languages or locales from the words in the user'"'"'s set of one or more databases;

selecting a subset of the set of one or more pronunciation guessers, the subset selected based upon the set of languages or locales that were automatically determined from the words in the user'"'"'s set of one or more databases; and

wherein the processing which produces the additional phonetic data uses only the subset of the set of one or more pronunciation guessers when producing the additional phonetic data.

16. The method as in claim 13 wherein the method is performed by a server that is coupled through a wireless network to the user'"'"'s device which includes the contacts database and wherein the server obtains the words in the contacts database from the user'"'"'s device through the wireless network and wherein the server receives the speech input from the user'"'"'s device through the wireless network and wherein the server transmits the best match to the user'"'"'s device through the wireless network.

17. The medium as in claim 12 wherein the method is performed by the user'"'"'s device which includes the contacts database.

18. A data processing system comprising:

an input device for receiving a speech input;

a set of one or more processors coupled to the input device;

a memory coupled to the set of one or more processors, the memory storing a phonetic dictionary for speech recognition and storing an extended phonetic dictionary for a user, the extended phonetic dictionary produced by processing, using a set of one or more pronunciation guessers, words in a user'"'"'s set of one or more databases, and the set of one or more processors processing the speech input by comparing phonemes detected in the speech input to the phonetic dictionary and to the extended phonetic dictionary to determine a best match.

19. The system as in claim 18 wherein the system is a server that is coupled through a wireless network to a user'"'"'s device which stores the set of one or more databases which include a contacts database, and wherein the input device is a network interface that is coupled to the wireless network and wherein the server transmits the best match to the user'"'"'s device through the wireless network, and wherein the speech input is for calling a telephone number in the contacts database or for sending a message to another user in the contacts database.

20. The system as in claim 18 wherein the user'"'"'s set of one or more databases includes a contacts database and changes in the contacts database are processed using the set of one or more pronunciation guessers to update the extended phonetic dictionary based on the changes, and wherein the set of one or more pronunciation guessers comprise pronunciation guessers for a plurality of locales, each locale having its own pronunciation guesser.
