Abstract

During operation of an electronic device such as a cellular telephone with a touch screen display or other electronic equipment, a voice recognition engine may gather data on spoken words. Data on the spoken words that are recognized may be maintained in a spoken word database maintained by an input processor with an autocorrection engine. A user may supply text input that contains mistyped words to the electronic device using the touch screen or a keyboard. The input processor may use the autocorrection engine to automatically replace mistyped words with corrected versions of the mistyped words. The corrected words may be displayed in real time as the user supplies the text input. The autocorrection engine may make word correction decisions based at least partly on information in the spoken word database.

Claims

1. A method of operating an electronic device with a storage, processing circuitry and input-output circuitry including at least a microphone and a display, the method comprising:

recognizing spoken words;

storing spoken word data in a database corresponding to the recognized spoken words; and

after storing the spoken word data in the database;

receiving one or more text input characters;

performing an automatic correction process on at least a subset of the one or more text input characters based at least in part on the spoken word data stored in the database; and

after performing the automatic correction process, displaying on the display corrected text corresponding to at least one of the one or more text input characters.

2. The electronic device method of claim 1, wherein the spoken word data includes information on when the spoken words were spoken.

3. The method of claim 1, wherein:

the input-output circuitry comprises a touch screen; and

receiving the one or more text input characters comprises gathering the one or more text input characters as the user enters the one or more text input characters with the touch screen.

4. The method of claim 3, wherein the electronic device comprises a cellular telephone.

5. The method of claim 1, wherein performing the automatic correction process comprises automatically replacing a mistyped word in the one or more text inputcharacters with a replacement word without obtaining replacement word choice confirmation input at the electronic device from the user.

6. The method of claim 1, wherein performing the automatic correction process comprises automatically substituting a replacement word on the display in response to receiving a space character as part of the one or more text input characters.

7. The method of claim 1, wherein performing the automatic correction process comprises automatically replacing a mistyped word in the one or more text input characters with a replacement word in response to receiving a user-supplied confirmation of which of a plurality of displayed potential word replacements is to be used as the replacement word.

8. An electronic device, comprising:

a storage;

processing circuitry;

input-output circuitry including at least a microphone and a display; and

one or more programs, wherein the one or more programs are stored in the storage and configured to be executed by the processing circuitry, the one or more programs including instructions for;

recognizing spoken words;

storing spoken word data in a database corresponding to the recognized spoken words; and

after storing the spoken word data in the database;

receiving one or more text input characters supplied by a user of the electronic device;

performing an automatic correction process on at least a subset of the one or more text input characters based at least in part on the spoken word data stored in the database; and

after performing the automatic correction process, displaying on the display corrected text corresponding to at least one of the one or more text input characters.

9. The electronic device of claim 8, wherein the spoken word data includes information on when the spoken words were spoken.

10. The electronic device of claim 8, wherein:

the display comprises a touch screen; and

receiving one or more text input characters comprises gathering the one or more text input characters as the user enters the one or more text input characters with the touch screen.

11. The electronic device of claim 10, wherein the electronic device comprises a cellular telephone.

12. The electronic device of claim 8, wherein performing the automatic correction process comprises automatically replacing a mistyped word in the one or more text input characters with a replacement word without obtaining replacement word choice confirmation input at the electronic device from the user.

13. The electronic device of claim 8, wherein performing the automatic correction process comprises automatically substituting a replacement word on the display in response to receiving a space character as part of the one or more text input characters.

14. The electronic device of claim 8, wherein performing the automatic correction process comprises automatically replacing a mistyped word in the one or more text input characters with a replacement word in response to receiving a user-supplied confirmation of which of a plurality of displayed potential word replacements is to be used as a replacement word.

15. A non-transitory computer-readable medium storing instructions for operating an electronic device, which, when executed by the device with a storage, processing circuitry and input-output circuitry including at least a microphone and a display, cause the device to perform operations comprising:

recognizing spoken words;

storing spoken word data in a database corresponding to the recognized spoken words; and

after storing the spoken word data in the database;

receiving one or more text input characters;

performing an automatic correction process on at least a subset of the one or more text input characters based at least in part on the spoken word data stored in the database; and

after performing the automatic correction process, displaying on the display corrected text corresponding to at least one of the one or more text input characters.

16. The non-transitory computer-readable medium of claim 15, wherein the spoken word data includes information on when the spoken words were spoken.

17. The non-transitory computer-readable medium of claim 15, wherein:

the input-output circuitry comprises a touch screen; and

receiving the one or more text input characters comprises gathering the one or more text input characters as the user enters the one or more text input characters with the touch screen.

18. The non-transitory computer-readable medium of claim 17, wherein the electronic device comprises a cellular telephone.

19. The non-transitory computer-readable medium of claim 15, wherein performing the automatic correction process comprises automatically replacing a mistyped word in the one or more text input characters with a replacement word without obtaining replacement word choice confirmation input at the electronic device from the user.

20. The non-transitory computer-readable medium of claim 15, wherein performing the automatic correction process comprises automatically substituting a replacement word on the display in response to receiving a space character as part of the one or more text input characters.

21. The non-transitory computer-readable medium of claim 15, wherein performing the automatic correction process comprises automatically replacing a mistyped word in the one or more text input characters with a replacement word in response to receiving a user-supplied confirmation of which of a plurality of displayed potential word replacements is to be used as the replacement word.
