Abstract

Embodiments of the present invention improve content selection systems and methods using speech recognition. In one embodiment, the present invention includes a speech recognition method comprising receiving location parameters from a global positioning system, retrieving location data using the location parameters, and configuring one or more recognition sets of a speech recognizer using the location data.

Claims

1. A speech recognition method comprising:

receiving location parameters from a global positioning system;

retrieving location data using the location parameters; and

configuring one or more recognition sets of a speech recognizer using the location data.

2. The method of claim 1 further comprising automatically reconfiguring the one or more recognition sets if the location parameters change.

3. The method of claim 1 wherein the recognition sets are reconfigured if the location parameters change by a predetermined amount.

4. The method of claim 3 wherein the location parameters comprise a position, and wherein the one or more recognition sets are reconfigured if the position changes a predetermined amount.

5. The method of claim 1 wherein the location data is retrieved based on speed.

6. The method of claim 1 wherein the location data is retrieved based on direction.

7. The method of claim 1 wherein the location data is retrieved based on position.

8. The method of claim 1 further comprising:

receiving a speech input signal; and

processing the speech input signal using the one or more recognition sets of said speech recognizer.

9. The method of claim 5 further comprising determining one or more destinations based on a recognition result.

10. The method of claim 5 further comprising accessing destinations based on a recognition result and said location parameters.

11. The method of claim 5 further comprising generating a plurality of recognition results and weighting said recognition results based on said location parameters.

12. The method of claim 5 further comprising activating a guidance program in response to the speech input signal and outputting guidance information.

13. The method of claim 1 wherein the location data comprises a plurality of names of restaurants, and wherein the names of the restaurants are configured in the one or more recognitions sets.

14. The method of claim 1 wherein the location data comprises a plurality of names of gas stations, and wherein the names of the gas stations are configured in the one or more recognitions sets.

15. The method of claim 1 wherein the location data comprises a plurality of street names, and wherein the street names are configured in the one or more recognitions sets.

16. The method of claim 1 wherein the location data comprises a plurality of names, and wherein the names are configured in the one or more recognitions sets.
