Abstract
Abstract In a telephone answering device, artificial intelligence sends an outgoing message to the caller upon receipt of an incoming call. When the caller responds, the artificial intelligence determines whether the caller's voice is registered with the device, and if so, particular messages are played to the caller. If the caller's voice is not registered, the caller is notified by the device, and he may receive his specific message by sending a touch tone code (e.g., telephone number) from his telephone.
