Abstract
A driving directions system loads into memory a limited subset of prerecorded, spoken utterances of geographic names from a mass media storage. The subset of spoken utterances may be limited, for example, to the geographic names within a predetermined radius (e.g., a few miles) of the driver'"'"'s present location. The present location of the driver may be manually entered into the driving directions system by the driver, or automatically determined using a global positioning system (“GPS”) receiver. As the vehicle moves from its present location, the driving directions system loads into memory new names from the mass media storage and overwrites, if necessary, those which are now geographically out of range. Based on the current location of the driving, the driving directions system can audibly output geographic names from the run-time memory.

33. A driving directions system, comprising:
-
a large storage media for storing utterances of geographic names;
a location determination module for obtaining a location of a vehicle;
a storage manager for (a) receiving the location from the location determination module, (b) retrieving a subset of the utterances of geographic names from the large storage media based on the location, and (c) storing the subset of the utterances of geographic names in a working storage;
a dialog manager for receiving (d) the location from the location determination module;
(e) a final destination, and (f) a map;
wherein the dialog manager retrieves at least one of the subset of the utterances from the working storage based on (d), (e) and (f); and
wherein the dialog manager audibly outputs the at least one of the subset of the utterances. - View Dependent Claims (34, 35)

36. A driving directions system, comprising:
-
an utterance storage means for storing compressed, digitally-encoded utterances of geographic names;
a location determination means for obtaining a location of a vehicle;
a storage manager for (a) receiving the location from the location determination means, (b) retrieving a subset of the compressed, digitally-encoded utterances of geographic names from the utterance storage means, wherein the subset comprises compressed, digitally-encoded utterances of geographic names geographically located within a predetermined area surrounding the location, (c) decompressing the subset of the compressed, digitally-encoded utterances into uncompressed utterances, and (d) storing the uncompressed utterances in a working storage; and
a dialog manager for receiving (e) the location from the location determination means;
(f) a final destination from a destination input means, and (g) a map from a map storage means;
wherein the dialog manager retrieves at least one of the uncompressed utterances from the working storage based on (e), (f) and (g); and
wherein the dialog manager instructs a speech playback means to audibly output the at least one of the uncompressed utterances. - View Dependent Claims (37)
