Abstract

L'invention concerne un procédé et un appareil permettant d'augmenter la qualité de perception de signaux de parole synthétisés. Selon l'invention, le filtre de synthèse à variation temporelle comprend une ou plusieurs sections de filtre d'ordre fractionnel, c'est-à-dire des sections de filtre présentant un ordre non entier. En général, les filtres de synthèse employés pour la synthèse de données de parole paramétriques présentent un ordre entier, et sont souvent constitués par une composition de sections de filtre du second ordre disposées en parallèle ou en cascade. Le filtre de synthèse de parole peut dans ce dernier cas être composé d'un ensemble de filtres du second ordre disposés en parallèle ou en cascade ou de sections de filtre décrites dans le brevet d'invention WO 00/72305.
