Abstract
Abstract A communication system renders improved service for users by announcing in a vocal message information about the call such as the called person's name, calling person's name and class of urgency of the call during the phase or ring. For paging the called person's name, a directory number assigned to each of telephone users is dialled, or for notifying the calling person's name, a memory card such as a magnetic card memorizing the identification code of a calling person is set on a calling terminal device, so that necessary information is transferred to the switching system. The information is edited and synthesized into a vocal message in the switching system or in each terminal device using the speech synthesizing technique, and it is announced on the called terminal device during the silent time of the phase of ring.
