Abstract

An improved voice-recognition system and method that uses location data to build a library of location-specific terms. In one embodiment, the cell site of a caller'"'"'s wireless telephone is used to determine the approximate geographic location of the user, and based on this location, a list of nearby landmarks is compiled for aide in voice recognition. These landmarks can include street and cross-street names, building names and address ranges, public parks, businesses, and other such landmarks that can easily identify the caller'"'"'s specific location. Further, based on the determined cell site location, it is not necessary for the user to identify his general location, such as in terms of city and state.

Claims

1. A method for voice recognition, comprising:

receiving a communication request from a calling device;

determining the location, within a first geographic area, of the calling device;

loading a list of geographic landmarks corresponding to the first geographic area, each geographic landmark having associated location data;

receiving a voice input from the calling device;

comparing the voice input to the list of geographic landmarks; and

determining the location, within a second geographic area smaller than the first geographic area, of the calling device based on the voice input.

2. The method of claim 1, wherein the first geographic area is the operating range of a wireless network base station.

3. The method of claim 1, wherein the geographic landmarks include street names.

4. The method of claim 1, wherein the second geographic area is a street intersection.

5. The method of claim 1, wherein the calling device is a wireless telephone.

6. The method of claim 1, wherein the voice input does not include the identification of a city or state.

7. The method of claim 1, further comprising identifying a wireless network base station in communication with the calling device.

8. A method for voice recognition, comprising:

receiving a communication request from a wireless device;

identifying a base station in communication with the wireless device;

determining the location of the base station;

loading a list of geographic landmarks within in an operating range of the base station;

receiving a voice input from the calling device;

comparing the voice input to the list of geographic landmarks; and

determining the location, within the operating range of the base station, of the calling device based on the voice input.

9. The method of claim 8, wherein the geographic landmarks include street names.

10. The method of claim 8, wherein the calling device is a wireless telephone.

11. The method of claim 8, wherein the voice input does not include the identification of a city or state.

12. The method of claim 8, further comprising determining the city and state location of the wireless device based on the location of the base station.

13. A telecommunication network system, comprising:

means for receiving a communication request from a wireless device;

means for identifying a base station in communication with the wireless device;

means for determining the location of the base station;

means for loading a list of geographic landmarks within in an operating range of the base station;

means for receiving a voice input from the calling device;

means for comparing the voice input to the list of geographic landmarks; and

means for determining the location, within the operating range of the base station, of the calling device based on the voice input.

14. The system of claim 13, wherein the geographic landmarks include street names.

15. The system of claim 13, wherein the calling device is a wireless telephone.

16. The system of claim 13, wherein the voice input does not include the identification of a city or state.

17. A computer program product tangibly embodied in a machine-readable medium, comprising:

instructions for receiving a communication request from a wireless device;

instructions for identifying a base station in communication with the wireless device;

instructions for determining the location of the base station;

instructions for loading a list of geographic landmarks within in an operating range of the base station;

instructions for receiving a voice input from the calling device;

instructions for comparing the voice input to the list of geographic landmarks; and

instructions for determining the location, within the operating range of the base station, of the calling device based on the voice input.

18. The computer program product of claim 17, wherein the geographic landmarks include street names.

19. The computer program product of claim 17, wherein the calling device is a wireless telephone.

20. The computer program product of claim 17, wherein the voice input does not include the identification of a city or state.

21. The computer program product of claim 17, further comprising instructions for determining the city and state location of the wireless device based on the location of the base station.
