Comparison of Aerodynamic and Elastic Properties in Tissue and Synthetic Models of Vocal Fold Vibrations

  • Jacob Michaud-Dorko,
  • Charles Farbos de Luzan,
  • Gregory R. Dion,
  • Ephraim Gutmark and
  • Liran Oren

Three laryngeal models were used to investigate the aerodynamic and elastic properties of vocal fold vibration: cadaveric human, excised canine, and synthetic silicone vocal folds. The aim was to compare the characteristics of these models to enhance...

Biophysics of Voice Onset: A Comprehensive Overview

  • Philippe H. DeJonckere and
  • Jean Lebacq

Voice onset is the sequence of events between the first detectable movement of the vocal folds (VFs) and the stable vibration of the vocal folds. It is considered a critical phase of phonation, and the different modalities of voice onset and their di...

During phonation, the vocal folds exhibit a self-sustained oscillatory motion, which is influenced by the physical properties of the speaker’s vocal folds and driven by the balance of bio-mechanical and aerodynamic forces across the glottis. Su...
