Abstract: [eng] [cze]
Different techniques for voice conversion based on nonlinear spectral envelope warping are presented. They enable transformation of an utterance of a source speaker into the utterance of a target speaker. The voice conversion algorithm is based on spectral speech analysis, frequency transformation, spectrum envelope warping and high quality cepstral speech synthesis. The described voice conversion approach also considers the change of speech prosody. Jsou popsány různé metody konverse hlasu založené na nelineární transformaci spektrální obálky. Umožňují transformaci promluvy zdrojového mluvčího na promluvu cílového mluvčího. Algoritmus konverse hlasu je založen na spektrální analýze, kmitočtové transformaci, modifikaci spektrální obálky a na vysoce kvalitní kepstrální syntéze řeči. Popsaná konverse hlasu zahrnuje také změnu prosodie.
