Title (EN) A METHOD OF SYNTHESIZING OF AN UNVOICED SPEECH SIGNAL
(FR) PROCEDE DE SYNTHESE D'UN SIGNAL VOCAL NON VOISE
Abstract: front page image
(EN)The present invention relates to a method of synthesizing a signal comprising th steps of: a) determining of a required pitch bell location on the signal to be synthesized. b) mapping of the required pitch bell location onto an original signal to provide a first pitch bell location, c) randomizing the first pitch bell location to provide a second pitch bell location, d) windowing of the original signal on the second pitch bell location to provide a pitch bell, e) placing the resulting pitch bell at the required pitch bell location within the domain of the signal to be synthesized, f) repeating of the steps a) to e) for all required pitch bell locations and performing an overlap and add operatio with respect to the pitch bells in order to synthesize the signal.
(FR)L'invention concerne un procédé de synthèse d'un signal, qui consiste à : a) déterminer l'emplacement requis de la courbe de hauteur en cloche ; b) mapper l'emplacement requis de la courbe de hauteur en cloche sur un signal original afin de fournir un premier emplacement de la courbe de hauteur en cloche; c) randomiser le premier emplacement de la courbe de hauteur afin de fournir un second emplacement de courbe de hauteur ; d) fenêtrer le signal original sur le second emplacement de courbe de hauteur en cloche de la seconde courbe de hauteur en cloche afin de fournir une courbe de hauteur en cloche ; e) répéter les étapes a) à d) pour tous les emplacements de courbe de hauteur en cloche requis et procéder à une opération de superposition et d'addition par rapport aux courbes de hauteur, en cloche en vue de la synthèse du signal.
