Abstract
Abstract The present invention is a speech module including a central processing unit, a memory, a continuously variable slope delta demodulator, and related filter, amplifier, and speaker circuits connected to a master controller in a reproduction machine. Upon sensing certain machine conditions, the master controller provides suitable signals to the voice response module. In response, the voice response module locates starting addresses and lengths of words and phrases and reproduces the appropriate response. In one embodiment, the speech module is connected to a shared line communication system.
