Title (EN) VOICE TRANSFORMATION WITH ENCODED INFORMATION
(FR) TRANSFORMATION VOCALE À L'AIDE D'INFORMATIONS CODÉES
Abstract: front page image
(EN)Method, system, and computer program product for voice transformation are provided. The method includes transforming a source speech using transformation parameters, and encoding information on the transformation parameters in an output speech using steganography, wherein the source speech can be reconstructed using the output speech and the information on the transformation parameters. A method for reconstructing voice transformation is also provided including: receiving an output speech of a voice transformation system wherein the output speech is transformed speech which has encoded information on the transformation parameters using steganography; extracting the information on the transformation parameters; and carrying out an inverse transformation of the output speech to obtain an approximation of an original source speech.
(FR)L'invention porte sur un procédé, un système et un produit programme d'ordinateur pour transformation vocale. Le procédé consiste à transformer un signal vocal source à l'aide de paramètres de transformation, et à coder des informations sur les paramètres de transformation dans un signal vocal de sortie en utilisant la stéganographie, le signal vocal source pouvant être reconstruit à l'aide du signal vocal de sortie et des informations sur les paramètres de transformation. Un procédé de reconstruction de transformation vocale est également décrit, lequel consiste à : recevoir un signal vocal de sortie d'un système de transformation vocale, le signal vocal de sortie étant un signal vocal transformé qui a codé des informations sur les paramètres de transformation en utilisant la stéganographie ; extraire les informations sur les paramètres de transformation ; et effectuer une transformation inverse du signal vocal de sortie afin d'obtenir une approximation d'un signal vocal source d'origine.
