An answering device for answering callers on at least one telephone line, has a ring detector. The ring detector is adapted to be coupled to the telephone line for sensing an incoming call thereon. The detector can provide in response to this incoming call a ring signal. Also included is a central processor coupled to the ring detector. The processor can provide a command signal that varies according to a predetermined sequence, in response to successive occurrences of the ring signal. The answering device also has a voice synthesizer coupled to the central processor. The voice synthesizer is adapted to be coupled to the telephone line for providing thereon a speech signal waveform in response to the command signal.
