17. The non-transitory computer-readable media of claim 15 , wherein the navigation system data includes point-of-interest data.
15. Non-transitory computer-readable media bearing software instructions configured to instruct a processor to search navigation system data including phonetic data and text data stored in a storage device accessible from within a mobile platform, wherein the phonetic data includes a set of point-of-interest names in phonetic form, and the text data includes at least a portion of the same set of point-of-interest names in text form, by performing the steps of: receiving a representation of spoken utterance from a user; querying the phonetic data of the navigation system data with the spoken utterance to find a corresponding match; if a corresponding match is not found via the querying of the phonetic data, processing the representation of the spoken utterance to produce a dictation text substantially corresponding to the spoken utterance, wherein the dictation text is tuned for speech that is typical of navigation destination entry types; and querying the text data of the navigation system data with the dictation text using an approximate string matching criteria and producing a results list associated therewith.
