  • receiving a navigation-related voice-based input at an input mechanism associated with the navigation device, the voice-based input including at least a natural language utterance provided by a user;

    generating one or more preliminary interpretations of the natural language utterance using a dynamic recognition grammar associated with a speech recognition engine;

    analyzing the preliminary interpretations using a conversational language processor, the conversational language processor using shared knowledge and information associated with a navigation context to determine a probable interpretation of the natural language utterance in the navigation context; and

    communicating the probable interpretation of the natural language utterance to a navigation agent associated with the navigation context, the navigation agent operable to;

    identify one or more navigation-related requests contained in the voice-based input based on the probable interpretation of the natural language utterance; and

    resolve the requests using information associated with one or more of a plurality of information sources, the plurality of information sources including at least a navigation-specific information source.
