Analysis of the voice source in different phonation types: simultaneous high-sped imaging of the vocal fold vibration and glottal inverse filtering
Glottal flow waveforms estimated by inverse filtering acoustic speech pressure signals were compared to glottal area functions obtained by digital high-speed imaging of the vocal fold vibration. Speech data consisted of breathy, normal and pressed phonations produced by two male and one female subjects. The results yield both qualitative and quantitative information about the relationship betwe...

متن کاملThe effect of gas density on glottal vibration and exit jet particle velocity.
Although theoretical studies include a term for gas density in their mathematical descriptions of glottal aerodynamics, the effect of gas density on glottal vibration has not been examined empirically. In this study, an in vivo canine model was used to evaluate the effect of gas density on glottal vibration by comparing phonation with air and helium. With gas flow and nerve stimulation held con...
متن کاملNumerical glottal sound source model as coupled problem between vocal cord vibration and glottal flow
Understanding of dynamics of the speech production process may lead to a breakthrough in increasing the quality of synthesized voice and contribute to medical science with respect to treating voice disorder. However, little is known about mechanisms of speech dynamics, in particular about complex interactions of glottal flow and vocal fold vibration. In this paper, a two-dimensional viscoelasti...
متن کاملCause-effect relationship between vocal fold physiology and voice production in a three-dimensional phonation model.
The goal of this study is to better understand the cause-effect relation between vocal fold physiology and the resulting vibration pattern and voice acoustics. Using a three-dimensional continuum model of phonation, the effects of changes in vocal fold stiffness, medial surface thickness in the vertical direction, resting glottal opening, and subglottal pressure on vocal fold vibration and diff...
