Fifth International Workshop on Models and Analysis of Vocal Emissions for Biomedical Applications (MAVEBA 2007)
The study deals with mathematical modeling
of the vocal fold self-oscillations related to estimation
of the so-called output-cost-ratio (OCR), which is
computed from the numerically simulated sound
pressure level at the glottal level and the impact stress
(IS) during vocal folds collision. The dependence of
OCR on prephonatory glottal width, fundamental
frequency and lung pressure is discussed and partly
compared with a modified output cost ratio measured
in humans, where the closed quotient is used instead
