Abstract: The present invention relates to speech synthesis system wherein the acoustic message items are optically stored. The system according to the invention comprises: an optical store including a plurality of diffractive elements pertaining to the holographic technique. Each element is constructed for selectively projecting images carrying acoustic information in optical form; each projected image being coverted into electrical speech signals through an image converter tube associated with a loudspeaker. The image selection and its analysis are controlled by adresses supplied from a computer.
