receiving, by the computer system, a natural language utterance relating to a navigation context;

determining, by the computer system, one or more similarities between a user associated with the natural language utterance and one or more other users;

determining, by the computer system, a dynamic recognition grammar based on the one or more determined similarities; and

generating, by the computer system, one or more interpretations associated with the natural language utterance based on the dynamic recognition grammar.

6. The method of claim 1 , wherein the one or more determined similarities comprise a similar preference and a similar demographic profile between the user and the one or more other users.

7. The method of claim 1 , wherein the one or more determined similarities comprise a similar preference and a similar interest between the user and the one or more other users.

8. The method of claim 1 , wherein the one or more determined similarities comprise a similar demographic profile and a similar interest between the user and the one or more other users.

9. The method of claim 1 , wherein the one or more determined similarities comprise a similar preference, a similar demographic profile, and a similar interest between the user and the one or more other users.

10. The method of claim 1 , wherein the dynamic recognition grammar comprises one or more dictionaries or phrases for interpreting the natural language utterance.

11. The method of claim 1 , wherein the natural language utterance comprises one or more words from which a location is inferred, the method further comprising:

updating, by the computer system, the dynamic recognition grammar based on information relating to at least one of the inferred location, a current location of the user, or a route from the current location to the inferred location, wherein the information comprises at least one of traffic information, weather information, or event information relating to at least one of the inferred location, the current location, or the route; and

refining, by the computer system, the one or more interpretations associated with the natural language utterance based on the updated dynamic recognition grammar.

12. The method of claim 11 , the method further comprising:

determining, by the computer system, the information relating to at least one of the inferred location, the current location, or the route based on preference information associated with the user.

13. The method of claim 1 , wherein the natural language utterance comprises one or more words from which a location is inferred, the method further comprising:

determining, by the computer system, information relating to the inferred location based on preference information associated with the user;

updating, by the computer system, the dynamic recognition grammar based on information relating to the inferred location; and

refining, by the computer system, the one or more interpretations associated with the natural language utterance based on the updated dynamic recognition grammar.

14. The method of claim 1 , the method further comprising:

receiving, by the computer system, a subsequent natural language utterance;

updating, by the computer system, the dynamic recognition grammar based on the subsequent natural language utterance; and

refining, by the computer system, the one or more interpretations associated with the natural language utterance based on the updated dynamic recognition grammar.

15. The method of claim 1 , wherein the natural language utterance is received at an input device coupled to a navigation device, the method further comprising:

determining, by the computer system, a current location associated with the navigation device, wherein the dynamic recognition grammar is further determined based on the current location.

16. The method of claim 15 , the method further comprising:

downloading, by the computer system, the dynamic recognition grammar to the navigation device from a remote source, wherein a size of the dynamic recognition grammar is constrained based on one or more computing resources available to the navigation device.

17. The method of claim 1 , wherein the natural language utterance comprises one or more words from which a location is inferred, and wherein the dynamic recognition grammar is further determined based on: (1) information related to at least one of the inferred location, a current location relating to the user, or a route from the current location to the inferred location, (2) one or more topological domains associated with the current location, a subsequent natural language utterance, and/or (3) an availability of computing resources in the navigation device.

18. The method of claim 17 , wherein the one or more topological domains are selected based on a geographic proximity between the current location and the one or more topological domains.

19. The method of claim 17 , the method further comprising:

updating, by the computer system, the dynamic recognition grammar in response to one or more changes to the one or more topological domains.

20. A system for facilitating dynamic-recognition-grammar-based interpretation of one or more natural language utterance, the system comprising:

one or more physical processors programmed with computer program instructions which, when executed, cause the one or more physical processors to:

receive a natural language utterance relating to a navigation context;

determine one or more similarities between a user associated with the natural language utterance and one or more other users;

determine a dynamic recognition grammar based on the one or more determined similarities; and

generate one or more interpretations associated with the natural language utterance based on the dynamic recognition grammar.

21. The system of claim 20 , wherein the one or more determined similarities comprise at least one of a similar preference, a similar demographic profile, or a similar interest between the user and the one or more other users.

22. The system of claim 20 , wherein the natural language utterance comprises one or more words from which a location is inferred, and wherein the one or more physical processors are further caused to:

update the dynamic recognition grammar based on information relating to at least one of the inferred location, a current location of the user, or a route from the current location to the inferred location, wherein the information comprises at least one of traffic information, weather information, or event information relating to at least one of the inferred location, the current location, or the route; and

refine the one or more interpretations associated with the natural language utterance based on the updated dynamic recognition grammar.

23. The system of claim 22 , wherein the one or more physical processors are further caused to:

determine the information relating to at least one of the inferred location, the current location, or the route based on preference information associated with the user.

24. The system of claim 20 , wherein the natural language utterance comprises one or more words from which a location is inferred, and wherein the one or more physical processors are further caused to:

determine information relating to the inferred location based on preference information associated with the user;
