Study of intrinsic pitch of vowels [link]Paper  doi  abstract   bibtex   
It is established that high vowels have a higher intrinsic pitch than low vowels. But we found that nasalization of these vowels reduces this difference which vanishes in the case of French nasal vowels. These phenomena can be due to the combination of the following three types of source-tract coupling: (a) For very closed vowels, the vocal-tract constriction introduces an air-flow resistance which tends to raise the intraoral pressure and thus reducing the pressure difference across the glottis. This effect alone could account for a slight decrease in voice fundamental frequency. (b) The input impedance of the supraglottal cavities represents the voice-source acoustic load. We studied this type of coupling in simulating a nonlinear two-mass vocal-cord model loaded by an equivalent circuit of the vocal tract driving point impedance. It is found that the fundamental frequency decreases when the first formant frequency or bandwidth is lowered. (c) It is known that a mechanical interdependance exists between the supraglottal configuration and larynx position. Larynx movements change the vocal cord mechanical characteristics and consequently the oscillation frequency. From our results, it seems that the third type of coupling is predominant and could explain the intrinsic pitch of vowels.
