Abstract: A programmable doorbell controller for the operation of a doorbell. In a preferred embodiment, an audible announcement is recorded and stored by a doorbell control module using speech controller integrated circuitry. A self-contained remote module may interface with the doorbell control module by means of a wireless intercom system. When the doorbell actuation means is actuated, the remote module transmits a tone or signal that is received and detected by the doorbell control module. In response, the doorbell control module activates an internal speech controller circuitry to generate a playback of a stored audible announcement. Similarly, a visitor can easily respond by actuating a recording actuation means to activate a microphone for generating a responsive audible message that can be transmitted to the control module for encoding and storage. In this manner, the visitor's audible message is encoded, recorded and stored by the speech controller integrated circuitry of the control module for playback.
