The call circuit part(20) transmits and receives voice signals between mobile terminals. The microprocessor(30) is driven by the power supplied from a power supply part(31). If a key signal for voice dialing is inputted, the microprocessor(30) transmits an announcement voice signal, previously stored in a memory(32), to the voice input/output part(10). If a caller's voice is identical to a caller's announcement voice previously stored in the memory(32), the microprocessor(30) relays the transmitting and receiving voice signals transferred through the call circuit part(20) and the voice input/output part(10) and initiates a call.
