This paper presents a simulation framework that enables a glottal chink model to be integrated into a time-domain continuous speech synthesizer along with self-oscillating vocal folds. The glottis is then made up of two main separated components: a self-oscillating part and a constantly open chink. This feature allows the simulation of voiced fricatives, thanks to a self-oscillating model of the vocal folds to generate the voiced source, and the glottal opening that is necessary to generate the frication noise. Numerical simulations show the accuracy of the model to simulate voiced fricative, and also phonetic assimilation, such as sonorization and devoicing. The simulation framework is also used to show that the phonatory/articulatory space for generating voiced fricatives is different according to the desired sound: for instance, the minimal glottal opening for generating frication noise is shorter for /z/ than for /Z/.

In previous studies of the 1D vocal tract model of articulatory synthesis, subglottal pressure is typically regarded as constant, ignoring its dynamics. However, human vocalization is initially generated by glottal airflow via subglottal pressure change. This change is caused by the expansion and contraction of the lungs. In the current study, we propose a new pressure-volume model that relates pressure changes to volume changes of the human lung. Using this model, the behavior of the human lung can be integrated with articulatory synthesis. This model produces positive and negative subglottal pressure corresponding to expiration and inspiration respectively. In addition, breathing could be implemented in the proposed model. This implementation would expand the possibilities for articulatory synthesis.

Extension of the single-matrix formulation of the vocal tract: Consideration of bilateral channels and connection of self-oscillating models of the vocal folds with a glottal chink

Abstract: 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 glottal chink, to be connected to the vocal tract.
