Individual difference and acoustic effect of female laryngeal cavities

Abstract: 

This study examines the acoustic effect of the laryngeal cavity of female speakers on the higher vowel spectra. To do so, MRI data of vowels /a/ and /i/ obtained from three female speakers were analyzed with data from a male speaker as reference. 3D vocal-tract shapes were extracted from the MRI data and printed as solid mechanical models. Transfer functions of the models' vocal tracts were estimated by a transmission line model. Individual variations of the laryngeal cavity were described by the area functions of the cavity. It is observed that female laryngeal cavities tend to have relatively stable cross-sectional areas in comparison to the male's cavity. Acoustic experiments were conducted using the solid vocal-tract models with different glottal conditions simulated by different hole sizes of the glottal coupler. The result suggests that female laryngeal cavities exhibit spectral changes in the wider frequencies at about 3-4.5 kHz in vowels /a/ and /i/ in comparison of data between open and closed conditions of the glottis.
