Speech Conversion Using a Mixed-phase Cepstral Vocoder.
Martin Vondra, Robert Vích · ASEP · 2010
In the study a conversion of the voice character using a modification of the glottal pulse is described. The glottal signal is estimated by homomorphic speech deconvolution of the speech signal into the maximum- and minimum-phase parts. The maximum-phase part is an approximation of the glottal signal. For speech reconstruction the parametric mixed phase speech generation model based on the complex cepstrum is used.
