Abstract

The present invention relates to a system and method for speech recognition that receives speech input and converts the speech input to data. A database is accessed to determine stored data corresponding to the speech input data. The stored data is associated with desired output data. The output data is output to a user as speech output. The speech output data may be in the same voice as the user to enhance comprehension and clarity. The present invention may be used in sorting mail in which a street address or post office box number is spoken into the system and the system provides desired information in the form of speech. The desired information may include carrier route number, mail-forwarding information, mail hold information or fee payment information but is not so limited. The present invention may also be used to provide excerpts of written material to a user on command, such as a desired chapter/verse of the Bible.

Claims

1. A method of voice recognition of a user for sorting mail items, the method comprising:

receiving a first voice input of the user, said first voice input comprising a limited grammar corresponding to address information;

converting said first voice input into a first data;

identifying a second data in a database based on said first data, said second data being associated with said first data;

assembling output information from stored data based on said second data, said stored data being derived from voice input from the user;

converting the assembled output information corresponding to said second data into an audible output corresponding to the voice of the user.

2. The method of claim 1 further comprising receiving a third voice input of the user prior to receiving the first voice input of the user wherein said stored data is derived from said third voice input of the user

3. The method of claim 2 wherein the third voice input comprises digits.

4. The method of claim 1 wherein the first voice input comprises a predetermined set of phonemes.

5. The method of claim 1 wherein the first voice input comprises at least one of a destination street address or a destination post office box number of a mail item.

6. The method of claim 1 wherein the second data comprises information on the destination of a mail item.

7. A system of voice recognition of a user for sorting mail items, said system comprising:

a voice user interface for receiving a first voice input said first voice input comprising a limited grammar corresponding to address information;

a speech recognition engine for converting said first voice input into a first data;

an application unit for identifying second data based on said first data, said second data comprising output information associated with said first data, said output information being assembled from data stored in said database, the data stored in said database being derived from voice input from the user;

a text-to-speech engine for converting the assembled data corresponding to said second data into an audible output corresponding to the voice of the user.

8. The system of claim 7 wherein the voice user interface further receives a third voice input of the user prior to receiving the first voice input of the user wherein said data stored in said database is derived from said third voice input of the user.

9. The system of claim 8 wherein the third voice input comprises digits.

10. The system of claim 7 wherein the first voice input comprises a predetermined set of phonemes.

11. The system of claim 7 wherein the first voice input comprises at least one of a destination street address or a destination post office box number of a mail item.

12. The system of claim 7 wherein the second data comprises information on the destination of a mail item.

13. A computer readable medium comprising executable code for performing the steps of:

receiving a first voice input of the user, said first voice input comprising a limited grammar corresponding to address information;

converting said first voice input into a first data;

identifying a second data in a database based on said first data, said second data being associated with said first data;

assembling output information from stored data based on said second data, said stored data being derived from voice input from the user;

converting the assembled output information corresponding to said second data into an audible output corresponding to the voice of the user.

14. The computer readable medium of claim 13 further comprising receiving a third voice input of the user prior to receiving the first voice input of the user wherein said stored data is derived from said third voice input of the user.

15. The computer readable medium of claim 14 wherein the third voice input comprises digits.

16. The computer readable medium of claim 13 wherein the first voice input comprises a predetermined set of phonemes.

17. The computer readable medium of claim 13 wherein the first voice input comprises at least one of a destination street address or a destination post office box number of a mail item.

18. The computer readable medium of claim 13 wherein the second data comprises information on the destination of a mail item.

19. A method of voice-recognition for providing information from a database, said method comprising:

receiving a first voice input from a user;

parsing the first voice input into phonemes;

storing said phonemes in a database;

receiving a second voice input from said user and converting the second voice input into first data;

locating second data in memory corresponding to said first data;

converting said second data into a speech signal, said speech signal comprising words assembled from said phonemes stored in said database;

outputting said speech signal as voice output.

20. The method of claim 19 wherein said first voice input comprises predetermined text.

21. The method of claim 19 wherein said first data comprises at least one of a street address or a post office box number.

22. The method of claim 21 wherein said first data comprises a street address and said second data comprises destination information, said destination information corresponding to said street address.

23. The method of claim 21 wherein said first data further comprises an element selected from the group consisting of a name of a city, a name of a state, and a zip code.

24. The method of claim 21 wherein said voice output is in the same voice as said second voice input.

25. A system of voice-recognition for providing information from a database, said system comprising:

a voice user interface for receiving a first voice input and a second voice input from a user;

a processor for parsing the first voice input into phonemes and storing said phonemes in a database and converting said second voice input into first data;

a program for locating second data in memory corresponding to said first data;

a processor for assembling said phonemes stored in said database into a speech signal based on said second data;

an output for outputting said speech signal as voice output.

26. The system of claim 25 wherein said first voice input comprises predetermined text.

27. The system of claim 25 wherein said first data comprises at least one of a street address or a post office box number.

28. The system of claim 27 wherein said first data comprises a street address and said second data comprises destination information, said destination information corresponding to said street address.

29. The system of claim 27 wherein said first data further comprises an element selected from the group consisting of a name of a city, a name of a state, and a zip code.

30. The system of claim 25 wherein said voice output is in the same voice as said second voice input.
