This paper analyzes the interaction between the vocal folds and vocal tract at phonation onset due to the acoustical coupling between both systems. Data collected from a mechanical replica of the vocal folds show that changes in vocal tract length induce fluctuations in the oscillation threshold values of both subglottal pressure and frequency. Frequency jumps and maxima of the threshold pressure occur when the oscillation frequency is slightly above a vocal tract resonance. Both the downstream… 

Modal locking between vocal fold and vocal tract oscillations: Experiments and statistical analysis

The human vocal folds are known to interact with the vocal tract acoustics during voiced speech production; namely a nonlinear source-filter coupling has been observed both by using models and in

Interaction Mechanisms between Glottal Source and Vocal Tract in Pitch Glides

In simulated glottal flow waveforms, the tendency towards a formant ripple increases when acoustic feedback to glottAl flow is enabled, whereas the phenomenon occurs more rarely as a result of the direct acoustic pressure to vocal folds.

Experimental study on source-filter interaction using physical model of the vocal folds

The purpose of the present study is to reproduce the nonlinear phenomena induced by the source-filter interaction using physical models of the vocal folds and observed resonance effect, quenching, and subharmonics induced byThe nonlinear source- filter interaction as F1 crossed F0.

Modal locking between vocal fold and vocal tract oscillations: Simulations in time domain

It is well known that during voiced speech, the human vocal folds interact with the vocal tract acoustics. The resulting source-lter coupling has been observed using mathematical and physical models

Modeling of aerodynamic interaction between vocal folds and vocal tract during production of a vowel-voiceless plosive-vowel sequence.

Simulation results suggest that the realization of an occlusion of the vocal tract produces a passive increase in glottal area associated with a voice offset and that the expansion of the supraglottal cavity is responsible for the extension of the phonation up to 40 ms after closure of the lips.

Study of the effects of vocal tract constriction on glottal vibration.

Effects of constriction can indeed be observed in the features of glottal vibration as well as vocal tract resonances, as shown in the studies on speech and electroglottograph signals.

Acoustic and Aerodynamic Coupling during Phonation in MRI-Based Vocal Tract Replicas

Voiced speech is the result of a fluid-structure-acoustic interaction in larynx and vocal tract (VT). Previous studies show a strong influence of the VT on this interaction process, but are limited

Self-entrainment of the right and left vocal fold oscillators.

An analysis of entrained oscillations of the right and left vocal folds in the presence of asymmetries is presented, showing that the damping asymmetry expands the 1:1 entrainment region at low subglottal pressures across the whole asymmetry range.
