Sixth International Workshop on Models and Analysis of Vocal Emissions for Biomedical Applications (MAVEBA 2009)
The present contribution introduces three temporal measures of vocal fold opening as indicated by the time of decreasing contact of the vocal folds estimated from the electroglottogram signal. The sustained vowel [a:], produced when simulating the phonation types very pressed, pressed, neutral, strained (hyperfunctional) breathy and (hypofunctional) breathy, is analysed. The results indicate discrimination of phonation type along the adduction dimension for each of the measures of vocal fold opening duration.
