Abstract
An automatic message, time and temperature announcement system wherein the signals to be announced are stored in digitized form in a random access memory (32). Under control of a CPU (15), blocks of digitized speech signals are provided to a FIFO (35) and from there to a CVSD digital to analog converter (37), the output of which is coupled (41) to a plurality of telephone trunks (42). A digital counter timer peripheral (26) is used to maintain a count of the time of day (32) and the frequency output (49) of a voltage to frequency converter (48) connected to a temperature sensor (40). Loading of digitized speech signals, correction factors for time of day, and other controls may be accomplished remotely through a data link (27, 30) from a standard voice grade telephone line (31).
