An electronic conference system comprising:

• a plurality of voice input/output units;
• a plurality of user terminals for entering/displaying electronic document information and transmitting/receiving electronic documents;
• a conference server for accumulating electronic documents received from said plurality of user terminals, selecting an electronic document, which has been designated by a user terminal, from among the electronic documents accumulated, and transmitting the electronic document selected to the user terminal;
• a voice information management unit for accumulating voice information received from said plurality of voice input/output units, selecting prescribed voice information, which is designated by a user terminal, from among the voice information accumulated, and transmitting the voice information selected to said voice input/output units;
• network equipment for interconnecting said plurality of voice input/output units, said plurality of user terminals, said conference server and said voice information management unit having a table which indicates user identification information in correspondence with connection addresses of said voice input/output units and user terminals;
• wherein when conference participation requests are issued from said user terminals or said input/output units, said network equipment obtains user identification information corresponding to these user terminals or voice input/output units from said table and communicates this information to said conference server;
• said conference server collects conference attendee information on the basis of the user identification information communicated and creates an attendee list;
• wherein a prescribed user terminal enters conference conclusion time into said conference server before the conference convenes;
• said conference server monitors remaining conference time and, when the remaining conference time attains a prescribed time, connects said voice information management unit to voice input/output units of all attendees via said network equipment;
• and
• said voice information management unit sends voice guidance informing of remaining conference time to all voice input/output units.
