A voice annunciating system having an electronic memory for storing digital data representative of the analog audio signal of a plurality of predetermined sound components, selected series of said data being applied from said memory to a digital to analog converter adapted to produce an audio signal corresponding to the digital data applied thereto, by means of a control logic. The control logic is operative in response to an actuating signal associated with the desired message. Substantially all redundancy is eliminated from the digital data stored in the memory, said control logic being adapted to repetitively apply individual sound components or series of sound components to the digital to analog converter for reconstructing the desired message.
