Text to voice apparatus accessing multiple gazetteers dependent upon vehicular position

摘要

An apparatus that changes text data into a voice signal based on the position of a vehicle is disclosed. A main gazetteer is subdivided into multiple area gazetteers, wherein each area gazetteer contains information corresponding to the mapping area that the vehicle is located. When the vehicle's position moves to a different mapping area, an analysis controller detects the change in mapping area and selects the new corresponding area gazetteer. The information of the new area gazetteer is then outputted as speech. This technique of subdividing the main gazetteer into area gazetteers increases the retrieval speed of information to the operator of the vehicle.
