To prevent the payment of wasteful charge by measuring and editing the listening charge of a program announcement as occasion calls and instructing the sending of the program announcement and a charge information announcement from a voice storing means.

When a service exchange part 3 receives a charge information request, the exchange part 3 sends the editing instruction of a call charge and an information charge until the present time to a service control part 6. Then the control part 6 edits the call charge and the information charge until the present time and after then the voice storing part 4 sends a request for sending a charge information announcement based on the edited call and information charges to the exchange part 3. The exchange part 3 acquires a line for charge the information announcement with the storing part 4 and after then the storing part 4 temporarily stops the program announcement to send the charge information announcement to a transmission terminal equipment 2. At the same time, information that the announcement is normally sent is informed to the control part 6 through the exchange part 3.
