Title (EN) TARGETED VOCAL TRANSFORMATION
(FR) TRANSFORMATION VOCALE CIBLEE
Abstract:
(EN) The invention is a method for transforming a source individual's voice so as to adopt the characteristics of a target individual's voice. The excitation signal component of the target individual's voice is extracted and the spectral envelope of the source individual's voice is extracted. The transformed voice is synthesized by applying the spectral envelope of the source individual to the excitation signal component of the voice of the target individual. A higher quality transformation is achieved using an enhanced excitation signal created by replacing unvoiced and unsuitably voiced regions of the signal with data from appropriate voiced regions. Various methods of transforming the spectral characteristics of the source individual's voice are also disclosed.
(FR) Cette invention concerne un procédé permettant de transformer la voix d'un individu source en lui faisant prendre les caractéristiques de la voix d'un individu cible. On extrait la composante de signal d'excitation de la voix de l'individu cible, de même que l'enveloppe spectrale de la voix de l'individu source. La voix transformée est synthétisée en appliquant l'enveloppe spectrale de l'individu source à la composante du signal d'excitation de la voix de l'individu cible. Une transformation d'une meilleure qualité peut être obtenue en utilisant un signal d'excitation accru qui est généré en remplaçant les zones du signal non prononcées ou mal prononcées par des données provenant de zones prononcées correctement. Cette invention concerne également divers procédés de transformation des caractéristiques spectrales de la voix de l'individu source.
