ABSTRACT:
Human speech is coded by singling out from a transfer function of the speech, all poles that are unrelated to any particular resonance of a human vocal tract model. All other poles are maintained. A glottal pulse related sequence is defined representing the singled out poles through an explicitation of the derivative of the glottal air flow. Speech is outputted by a filter based on combining the glottal pulse related sequence and a representation of a formant filter with a complex transfer function expressing all other poles. The glottal pulse sequence is modelled through further explicitly expressible generation parameters. In particular, a non-zero decaying return phase supplemented to the glottal-pulse response that is explicitized in all its parameters, while amending the overall response in accordance with volumetric continuity.
