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.

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; and

recognizing, using a speech recognition module, the identifier based on the type of business.

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.

6. The method of claim 5 wherein providing information about the specific business comprises providing a phone number of the specific business.

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.

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, the geographical location and the category; and

recognizing, using the speech recognition module, the name based on the geographical location and the category.

12. The method of claim 11 wherein the entity comprises a profit organization, a non-profit 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.
