Dynamic geo-fencing for voice recognition dictionary

1. A computer-implemented method, comprising:

obtaining, by an electronic device from at least one global positioning system (GPS), location parameters comprising a location of the electronic device, a direction of travel of the electronic device and a speed of the electronic device;

configuring, by the electronic device, a dynamic geo-fenced area based on the location parameters, wherein the dynamic geo-fenced area surrounds the location of the electronic device;

retrieving, by the electronic device, a Voice Recognition (VR) dictionary subset comprising data associated with the dynamic geo-fenced area from a VR dictionary, wherein the data comprise a broadcast station name and a broadcast frequency associated with the broadcast station name; and

performing voice recognition using the VR dictionary subset.

2. The method of claim 1 , further comprising:

determining, by the electronic device, that the speech comprises a desired broadcast station name;

determining the frequency associated with the desired broadcast station name; and

requesting, by the electronic device, that a broadcast tuner tune to the associated frequency.

3. The method of claim 1 , wherein the dynamic geo-fenced area is off-centered from the location of the electronic device along the direction of travel of the electronic device.

4. The method of claim 1 , further comprising:

receiving second location parameters;

determining that the second location parameters indicate travel of the electronic device above a threshold distance from the location;

retrieving, by the electronic device, a new VR dictionary subset pertaining to a new dynamic geo-fenced area surrounding the second location parameters; and

reconfiguring, by the electronic device, the new VR dictionary subset as the VR dictionary subset in use.

5. The method of claim 1 , wherein an update frequency of retrieving the VR dictionary subset is based on the speed of travel of the electronic device.

6. The method of claim 1 , wherein a size of the dynamic geo-fenced area is based on the speed of travel of the electronic device.

7. The method of claim 1 , wherein the broadcast tuner is configured to tune to one or more of an AM radio broadcast, an FM radio broadcast, a satellite radio broadcast, a terrestrial television broadcast and a satellite television broadcast.

8. The method of claim 1 , wherein the retrieving comprises adjusting the VR dictionary subset to comprise broadcast station names for the dynamic geo-fenced area.

9. The method of claim 1 , further comprising:

receiving, by the electronic device, broadcast station names via a broadcast; and

adding the received broadcast station names into the VR dictionary.

10. The method of claim 1 , wherein the VR dictionary subset further comprises names of points-of-interest in the dynamic geo-fenced area.

11. A mobile electronic device, comprising:

a broadcast tuner configured to receive tuning commands; and

a voice recognizer for communicating spoken commands to the broadcast tuner, wherein the voice recognizer is configured to

obtain, from at least one global positioning system (GPS), location parameters comprising a location of the electronic device, a direction of travel of the electronic device and a speed of the electronic device,

configure a dynamic geo-fenced area based on the location parameters, wherein the dynamic geo-fenced area surrounds the location,

retrieve a Voice Recognition (VR) dictionary subset comprising data associated with the dynamic geo-fenced area from a VR dictionary, wherein the data comprise a broadcast station name and a frequency associated with the broadcast station name, and

perform voice recognition using the VR dictionary subset.

12. The device of claim 11 , where the voice recognizer is further configured to:

determine that the speech comprises a desired broadcast station name;

determine the frequency associated with the desired broadcast station name; and

request that the broadcast tuner tune to the associated frequency.

13. The device of claim 11 , wherein the dynamic geo-fenced area is off-centered from the location of the electronic device along the direction of travel of the electronic device.

14. The device of claim 11 , where the voice recognizer is further configured to:

receive second location parameters;

determine that the second location parameters indicate travel of the electronic device above a threshold distance from the location;

retrieve a new VR dictionary subset pertaining to a new dynamic geo-fenced area surrounding the second location parameters; and

reconfigure the new VR dictionary subset as the VR dictionary subset in use.

15. The device of claim 11 , wherein an update frequency of retrieving the VR dictionary subset is based on the speed of travel of the electronic device.

16. The device of claim 11 , wherein a size of the dynamic geo-fenced area is based on the speed of travel of the electronic device.

17. The device of claim 11 , wherein the broadcast tuner is configured to tune to one or more of an AM radio broadcast, an FM radio broadcast, a satellite radio broadcast, a terrestrial television broadcast and a satellite television broadcast.

18. The device of claim 11 , wherein the voice recognizer is further configured to adjust the VR dictionary subset to comprise broadcast station names for the dynamic geo-fenced area.

19. The device of claim 11 , wherein the voice recognizer is further configured to receive broadcast station names via a broadcast and add the received broadcast station names into the VR dictionary.

20. The device of claim 11 , wherein the VR dictionary subset further comprises names of points-of-interest in the dynamic geo-fenced area.
