Abstract
Abstract In an intelligent work station of this invention, map information for a target is stored in a database. Word speech data input through a telephone line is recognized and analyzed, and the database is retrieved accordingly, so that map information specified by the speech input is extracted from the database. The map information is transmitted to a destination communication terminal. When the destination communication terminal does not have an image output function, the map information is analyzed, and document data representing the content of the map is created. The document data is speech-synthesized, and is output to the destination communication terminal via the telephone line.
