Original Abstract

Different techniques for voice conversion based on nonlinear spectrum envelope warping, developed in the Institute of Radio Engineering and Electronics, CAS, 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. The fundamental frequency and intensity modifications are based on matching the means and standard deviations of these parameters for the source and target speakers. Speech rate modification is realized by a time modification factor.
