Abstract

L'INVENTION CONCERNE UN CONVERTISSEUR DE DONNEES POUR UN SYNTHETISEUR DE PAROLE. UNE SEQUENCE BINAIRE D'ENVIRON 300 BITS PAR SECONDE CONTENANT DES INFORMATIONS DE HAUTEUR, D'ENERGIE ET DE FREQUENCE CENTRALE EST DECODEE. LES DONNEES DE FREQUENCE CENTRALE DE SONS DE VOYELLES SONT CONVERTIES EN TEMPS REEL EN DES COEFFICIENTS DE REFLEXION AU MOYEN D'UN CIRCUIT QUI EFFECTUE UNE APPROXIMATION SOUS FORME D'UN DEVELOPPEMENT EN SERIE DE TAYLOR. L'INVENTION S'APPLIQUE NOTAMMENT A UN SYNTHETISEUR DE PAROLE EN CIRCUIT INTEGRE.
