Patent ID: 7313522

Claim:
A voice synthesis system comprising a plurality of portable terminals and a server which are connectable to each other via communication lines, wherein: each of the portable terminals comprises a text data receiving unit for receiving text data from another portable terminal, a text data transmitting unit for attaching a voice sampling name to the received text data and transmitting the text data to the server, a voice synthesis data receiving unit for receiving voice synthesis data from the server, and a voice reproducing unit for reproducing the received voice synthesis data in a voice; and the server comprises a text data receiving unit for receiving the text data and the voice sampling name from the portable terminal, a voice synthesizing unit for converting the received text data into the voice synthesis data by using voice sampling data corresponding to the received voice sampling name, and a voice synthesis data transmitting unit for transmitting the converted voice synthesis data to the portable terminal, wherein the server converts the received text data into the voice synthesis data using voice data stored at the server corresponding to the received voice sampling name and not based on any voice information that may or may not have been sent along with the text data output from the another portable terminal to the portable terminal, wherein each of the portable terminals has a provisional database access permission ID assigned thereto by the server for use in storing voice data of a user of said each of the portable terminals, and wherein, when one of the portable terminals outputs the text data to another of the portable terminals, the one of the portable terminals includes the provisional database access right ID with the text data, which thereby enables the server to use voice data of the user of the another of the portable terminals in performing voice synthesis of the text data to be sent to the one of the portable terminals.
