Voice Synthesis System Based on Recursive Functions Designed by Graphs

A recursive function based on the use of graphs is presented. The recursive equation is based on mathematical morphology; A written text divided into syllables is related to phonemes of spoken Spanish in Mexico. The algorithm is implemented in a PIC and an integrated circuit that stores the sounds in memory locations. Each space in memory becomes a code that is related to a phoneme. Thus, the recursive function receives as input a vector that is the structure of a word; and outputs the corresponding memory locations. Obtaining intelligibility of more than 84%. The development of the recursive function in graphs is proposed, which allows an easy description of the sequence because it is handled as a black box with input and outputs; and the equation that governs the system can even be a transfer function.
