Abstract

Disclosed are systems, methods, and computer-readable media for disambiguating confusable speech using a table. The method embodiment provides assigning an identifier to each of at least one portion of received speech, querying a table to determine whether at least one entry is associated with the identifier, and if multiple entries are associated in the table with the identifier, then disambiguating between the multiple entries by generating a prompt to the user. Additional features include associating table entries that are not acoustically similar as confusable, presenting the items in the prompt in a sorted order, and dynamically modifying entries in the table.

Claims

1. A method of disambiguating potentially confusable speech, the method comprising:

assigning an identifier to each of at least one portion of received speech;

querying a table to determine whether at least one entry is associated with the identifier; and

,

if multiple entries are associated in the table with the identifier, then disambiguating between the multiple entries by generating a prompt to the user.

2. The method of claim 1, wherein for at least one identifier, there are multiple entries in the table that are associated as confusable for which the multiple entries do not have acoustic similarities.

3. The method of claim 1, wherein the prompt presents each of the multiple entries in a sorted order.

4. The method of claim 1, wherein an ASR grammar assigns the identifier to each of the at least one portion of speech.

5. The method of claim 4, wherein each possible output from the ASR grammar has a unique identifier.

6. The method of claim 1, wherein the method is practiced in an interactive voice response system.

7. The method of claim 1, wherein the identifier is unique for each portion of the received speech.

8. The method of claim 1, wherein table entries are modified dynamically.

9. The method of claim 8, wherein the table entries are modified either automatically or manually.

10. The method of claim 8, wherein characteristics of the received speech or characteristics of the speaker are used to dynamically modify table entries.

11. The method of claim 10, wherein at least one of a speaker'"'"'s language, location, or gender is used to dynamically modify table entries.

12. A system for disambiguating potentially confusable speech, the system comprising:

a module configured to assign an identifier to each of at least one portion of received speech;

a module configured to query a table to determine whether at least one entry is associated with the identifier; and

,

a module configured to if multiple entries are associated in the table with the identifier, then disambiguating between the multiple entries by generating a prompt to the user.

13. The system of claim 12, wherein for at least one identifier, there are multiple entries in the table that are associated as confusable for which the multiple entries do not have acoustic similarities.

14. The system of claim 12, wherein the prompt presents each of the multiple entries in a sorted order.

15. The method of claim 12, wherein table entries are modified dynamically.

16. A computer readable medium storing a computer program having instructions for controlling a computing device to disambiguate potentially confusable speech, the instructions comprising:

assigning an identifier to each of at least one portion of received speech;

querying a table to determine whether at least one entry is associated with the identifier; and

,

if multiple entries are associated in the table with the identifier, then disambiguating between the multiple entries by generating a prompt to the user.

17. The computer-readable medium of claim 16, wherein for at least one identifier, there are multiple entries in the table that are associated as confusable for which the multiple entries do not have acoustic similarities.

18. The computer-readable medium of claim 16, wherein the prompt presents each of the multiple entries either in a sorted order.

19. The computer-readable medium of claim 16, wherein table entries are modified dynamically.
