Phonation Models of Tone and Diatone in Mandarin

This paper is concerned with the study on the phonation models of tone and diatone in Mandarin. The method used in this study has 3 parts: 1) extracting glottal signal by inverse filtering; 2) extracting phonation parameters from glottal signal in time domain; 3) modeling the phonation natures of tones and diatones by polynomial curve fitting. There are 3 conclusions, which are 1) there are 3 types of phonation pulses, which are single peak pulse, double-peak pulse and tri-peak pulse; 2) F0 is in the inverse ratio of PR1 and PP1, which reflects the basic phonation natures of tones and diatones in Mandarin; 3) PR2 and PR3 have correlation with PP2 and PP3, which reflects the personal changes of phonation natures in different conditions.
