Abstract

The subject matter of this specification can be embodied in, among other things, a method that includes receiving geographical information derived from a non-verbal user action associated with a first computing device. The non-verbal user action implies an interest of a user in a geographic location. The method also includes identifying a grammar associated with the geographic location using the derived geographical information and outputting a grammar indicator for use in selecting the identified grammar for voice recognition processing of vocal input from the user.

Claims

1. (canceled)

2. A computer-implemented method comprising:

providing for display a map of a geographic region;

receiving voice data corresponding to an utterance to initiate a search;

in response to receiving the voice data corresponding to the utterance, updating the map to provide a visual indicator that identifies a location associated with a transcription of the utterance that is generated based on context information associated with the map.

3. The method of claim 2, wherein the context information comprises implicit geographical information that is derived from the map of the geographic region.

4. The method of claim 2, wherein the context information comprises geographical information derived from content that was previously provided for display.

5. The method of claim 2, further comprising:

transmitting geographical information about the map of the geographic region.

6. The method of claim 2, wherein the utterance identifies a location.

7. The method of claim 2, wherein the context information comprises a search history that identifies one or more search queries that were previously submitted to one or more search services by one or more computing devices that are associated with a user of the computing device.

8. The method of claim 2, wherein the transcription is generated using a dynamically selected grammar that is associated with a geographic location identified based on the context information.

9. The method of claim 8, wherein the geographic location is identified further based on search results that are associated with one or more search queries that were previously submitted.

10. A system comprising:

memory for storing data; and

a hardware processor operable to perform operations comprising;

providing for display a map of a geographic region;

receiving voice data corresponding to an utterance to initiate a search;

in response to receiving the voice data corresponding to the utterance, updating the map to provide a visual indicator that identifies a location associated with a transcription of the utterance that is generated based on context information associated with the map.

11. The system of claim 10, wherein the context information comprises implicit geographical information that is derived from the map of the geographic region.

12. The system of claim 10, wherein the context information comprises geographical information derived from content that was previously provided for display.

13. The system of claim 10, the operations further comprising:

transmitting geographical information about the map of the geographic region.

14. The system of claim 10, wherein the utterance identifies a location.

15. The system of claim 10, wherein the context information comprises a search history that identifies one or more search queries that were previously submitted to one or more search services by one or more computing devices that are associated with a user of the computing device.

16. The system of claim 10, wherein the transcription is generated using a dynamically selected grammar that is associated with a geographic location identified based on the context information.

17. The system of claim 16, wherein the geographic location is identified further based on search results that are associated with one or more search queries that were previously submitted.

18. A non-transitory, computer-readable medium storing instructions operable when executed to cause one or more processors to perform operations comprising:

providing for display a map of a geographic region;

receiving voice data corresponding to an utterance to initiate a search;

in response to receiving the voice data corresponding to the utterance, updating the map to provide a visual indicator that identifies a location associated with a transcription of the utterance that is generated based on context information associated with the map.

19. The computer-readable medium of claim 18, wherein the context information comprises implicit geographical information that is derived from the map of the geographic region.

20. The computer-readable medium of claim 18, wherein the context information comprises geographical information derived from content that was previously provided for display.

21. The computer-readable method of claim 18, wherein the transcription is generated using a dynamically selected grammar that is associated with a geographic location identified based on the context information.
