ABSTRACT:
A voice announcement technique of an electronic exchange system having a main processor for controlling a voice announcement function and a time switch which switches a voice announcement message to a subscriber interface unit includes a voice memory for storing coded data corresponding to words and pauses; a processor interface unit connected to the main processor, for interfacing a voice announcement command output from the main processor; a buffer unit connected to the processor interface unit, for buffering information for performing a voice announcement with the main processor; a digital signal processing unit connected to the buffer unit, for controlling the voice memory to access corresponding words and pauses if the voice announcement command has been received, thereby reproducing a voice announcement message; and an output device connected to the time switch via a sub highway, for outputting the voice announcement message to the sub highway under the control of the digital signal processing unit.
