Abstract

A method of operating a voice-enabled business directory search system includes prompting a user to provide a type of business and an identifier of a specific business, receiving from the user a speech input having information about the type of business and the identifier, and recognizing, using a speech recognition module, the identifier based on the type of business.

Claims

1. A method comprising:

prompting a user to provide a type of business and an identifier of a specific business;

receiving from the user a speech input having information about the type of business and the identifier;

recognizing the type of business from the speech input;

selecting a speech recognition module based on the type of business recognized from the speech input; and

recognizing, using the speech recognition module executing on one or more processors, the identifier from the speech input.

2. The method of claim 1 wherein prompting the user to provide information comprises prompting the user to provide a geographical location.

3. The method of claim 2 wherein recognizing the identifier comprises using the speech recognition module to recognize the identifier of the specific business based on the geographical location and the type of business.

4. The method of claim 1 wherein prompting the user for an identifier comprises prompting the user for a name of the specific business.

5. The method of claim 1, further comprising, after recognizing the identifier of the specific business, providing information about the specific business to the user.

7. The method of claim 5 wherein providing information about the specific business comprises providing a list of business names based on the recognition of the identifier of the specific business.

8. The method of claim 1 wherein recognizing the identifier of the specific business comprises biasing the speech recognition module towards one or more language models associated with the type of business.

9. The method of claim 1 wherein prompting the user for the type of business occurs before prompting the user for the identifier of the specific business.

10. The method of claim 1 wherein prompting a user to provide information comprises, using a single prompt, asking the user for the type of business and the identifier of the specific business.

11. A method comprising:

asking a user for a geographical location, a category, and a name of an entity;

receiving a speech input from the user having information about the geographical location, the category, and the name of the entity;

recognizing, using a speech recognition module executing on one or more processors, the geographical location and the category;

selecting a name speech recognition module based on the geographical location and the category; and

recognizing, using the selected name speech recognition module, the name.

12. The method of claim 11 wherein the entity comprises a profit organization, a nonprofit organization, or a person.

13. The method of claim 11 wherein recognizing the name comprises using one or more speech recognition language models associated with the geographical location and the category.

14. A method comprising:

receiving a geographical location and a type of business from a user;

selecting a speech recognition module based on the geographical location and type of business; and

recognizing, using the selected speech recognition module executing on one or more processors, a name of a specific business in a speech utterance of a user.

15. The method of claim 14 wherein the recognizing comprises using one or more language models associated with the type of business.

16. An apparatus comprising:

a voice-enabled user interface to output a voice prompt to request a user to provide a type of business and an identifier of a specific business, and receive from the user a speech input having information about the type of business and the identifier of the specific business; and

a speech recognition engine to select a speech recognition module based on the information about the type of business and recognize the identifier of the specific business using the selected speech recognition module.

17. The apparatus of claim 16 wherein the speech recognition engine biases toward speech recognition language models associated with the type of business provided by the user.

18. The apparatus of claim 16 wherein the voice prompt also requests the user to provide a geographical location.

19. The apparatus of claim 18 wherein the speech recognition engine biases toward speech recognition language models associated with the type of business and the geographical location provided by the user.

20. The apparatus of claim 16, further comprising a storage medium for storing a database comprising speech recognition language models, each language model for recognizing specific businesses associated with one or more particular types of businesses.

21. The apparatus of claim 16, further comprising a storage medium for storing a hierarchical tree of nodes, each node associated with one or more particular types of businesses.

22. The apparatus of claim 16, further comprising a storage medium for storing a script having instructions for controlling an interaction between the voice-enabled user interface and the user.

23. The apparatus of claim 16, further comprising a search engine to search for information related to the specific business based on the identifier of the specific business recognized by the speech recognition engine.

24. An apparatus comprising:

a voice-enabled search system comprising;
