In this paper a low-cost, small dimensions, multiple users audio response system using microprocessors and LSI circuits is presented, The synthesis strategy is performed by a MOS microprocessor, which provides 12 LPC parameters to a microprogrammable digital filter. The synthetic message is produced by a concatenation of units which range from words to dyad-like elements, depending on the application. The synthesis algorithm is based on two main steps: the segment concatenation rules and the prosodic rules. The fundamental frequency contour is defined by the type of sentence, the punctuation ma rks and the position of the accents.
