Abstract

Le signal de parole est caractérisé par une alternance de zones spectralement assez stables, entrecoupées de régions transitoires. Les systèmes de reconnaissance proposés par le passé reposent sur des propriétés de stabilité spectrale et de stationnarité; ils obtiennent des performances mitigées pour les régions de transition. Une représentation de ces régions par modèle AR évolutif, valide sur toute la durée d'une région transitoire, est proposée. Les coefficients du modèle dépendent du temps et s'expriment sur une base limitée de fonction temporelles. Cette méthode de représentation est appliquée à la reconnaissance de segments transitoires C-V extraits de parole naturelle, et comparée à des méthodes plus classiques.
