Title: Speech Conversion Using a Mixed-phase Cepstral Vocoder

Authors: Martin Vondra, Robert Vich

Abstract:

In the study a simple conversion of the voice character using a modification of the glottal pulse is shortly described. The glottal signal is estimated by homomorphic speech deconvolution of the speech signal into the maximum- and minimum-phase parts. The maximum-phasepart is an approximation of the glottal signal. For speech reconstruction the parametric mixed phase speech generation model based on the complex cepstrum is used, which takes into account not only the magnitude spectrum of the modeled speech frame, but also the phase spectrum.
