Abstract: When an internet access operation is conducted, a browser 2 demands acquisition or an HTML document from an HTTP server 11. When receiving the demand, the HTTP server 11 reads out contents 14 and transmits them to a terminal apparatus. The browser 2 Interprets the received contents 14, and if an exclusive tag for explaining an outline of the contents 14 exists, the browser sends an acquisition demand of a voice data 15 for explaining the outline of the contents to the HTTP server 11. When receiving the acquisition demand, the HTTP server 11 reads out the specified voice data 15, and transmits it to the browser 2. On a side of the browser 2, the voice data 15 is stored in a memory 6, and a regeneration demand of the downloaded voice data 15 is issued. A voice control section 9 regenerates the voice data 15 and outputs it from a speaker 10.
