| Research Abstract |
In the present study, experimental analysis of this vibration was made to clarify phonation mechanism and seek better modeling of vocal folds, focusing on direct measurement of subglottal pressure and glottal velocity and simultaneous observation of vocal fold movement by means of a high-speed digital camera. The experimental results prove that subglottal pressure increases in closing phase of vocal folds and decreases in opening phase and high speed airflow just above glottis results in closing of vocal folds.
