Abstract

There is a provided a mobile electronic device and a computer-implemented method. The method includes: receiving, by an electronic device, 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 comprises a broadcast station name and a broadcast frequency associated with the broadcast station name; and performing voice recognition using the VR dictionary subset.

Claims

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.
