12. A system for dynamically generating a recognition grammar in an integrated voice navigation services environment, comprising: an input device configured to receive a natural language utterance, wherein the natural language utterance relates to a navigation context; a location detection system configured to identify a current location associated with a navigation device; a conversational language processor configured to generate a dynamic recognition grammar that organizes grammar information based on one or more topological domains associated with the current location associated with the navigation device and configured to determine one or more affinities between a user that spoke the natural language utterance and one or more peers associated with the user, wherein the dynamic recognition grammar further organizes the grammar information according to the one or more determined affinities; and a speech recognition engine configured to generate one or more interpretations associated with the natural language utterance using the dynamic recognition grammar.
18. The system of claim 12 , wherein the conversational language processor is further configured to modify the grammar information in the dynamic recognition grammar in response to one or more changes to the one or more topological domains associated with the current location associated with the navigation device.
