Voiced speech is a highly complex process involving coupled interactions between the
vocal fold structure, aerodynamics, and acoustic field. Reduced-order lumped-element …

A model-based inverse filtering scheme is proposed for an accurate, non-invasive
estimation of the aerodynamic source of voiced sounds at the glottis. The approach, referred …

The paper presents extensions of the single-matrix formulation (Mokhtari et al., 2008,
Speech Comm. 50 (3) 179–190) that enable self-oscillation models of vocal folds, including …

This paper proposes a modular architecture for articulatory synthesis from a gestural
specification comprising relatively simple models for the vocal tract, the glottis, aero …

The hypopharyngeal cavities consist of the laryngeal cavity and bilateral piriform fossa,
constituting the bottom part of the vocal tract near the larynx. Visualisation of these cavities …

It is known that the right and left piriform fossae generate two deep dips on speech spectra
and that acoustic interaction exists in generating the dips: if only one piriform fossa is …

Among the several speech synthesis techniques available nowadays, Articulatory Vocal
(AV) synthesis is one of the most challenging. Differently from other speech technologies, an …

A time-domain model of sound wave propagation in the branching airways of the subglottal
system is presented. The model is formulated as an extension to an acoustic transmission …

Many aspects of the coupling between vocal fold motion, glottal airflow, and resulting sound
waves remain unexplored, particularly during incomplete glottal closure. In addition, this …

The paper presents a numerical study about the acoustic impact of the gradual glottal
opening on the production of fricatives. Sustained fricatives are simulated by using classic …
