PURPOSE:To provide a voice dialing service device which is capable of performing a voice dialing even from a conventional telephone set which is not equipped with a voice dialing device. CONSTITUTION:In the data base part 58 of an exchange 5, the telephone numbers of transmitters, passwords and opposite telephone numbers are preliminarily registered. When a number for voice dialing transmission is inputted from a transmission terminal 1, a control part 57 retrieves the data base part 58 and judges whether a call is the originating call from an already registered transmission terminal or not. In the case of the registered transmission terminal, a guidance urging the utterance of the password is transmitted from a voice response part 55 to the transmitter. When the voice input of the password is performed from the transmitter, this voice input is analyzed in a voice recognition part 56 via a domestic network 3. The control part 57 retrieves the data base part 58 from this analysis result and the telephone number of the transmitter and determines the opposite telephone number. Based on the opposite telephone number, the line of the transmission terminal 1 and an incoming terminal 2 is connected.
