Abstract
An automatic answering telephone set comprises a voice synthesizing unit and a voice detector for reproducing a recorded message in response to a remote control performed by using a predetermined password number. A plurality of decoy numerals are inserted immediately before each of numerals constituting the preestablished password number to thereby form a pseudo-password number including the decoy numerals. A calling party is inquired of with the pseudo-password number. An input password number is then formed in accordance with replies of the calling party as detected by the voice detector. Only when coincidence is found between the predetermined password number and the input numerical password, the remote control is accepted.
