Augmented M5 geometry of human vocal fold in phonatory position – pilot results

Popis výsledku v původním jazyce

Abstract: The presented contribution deals with a newly designed parametric planar geometry of the vocal fold – the augmented M5 model – which is fitted to a real-shaped human vocal fold. The real shape of the vocal fold during a phonatory position for 112 Hz was obtained from a plaster cast and was digitized by optical scanning. The geometry model of the vocal fold surfaces was constructed based on the data from the optical scanner and the augmented M5 model was fitted to a coronal slice of the selected vocal fold surface. The equations of the augmented M5 model are explained and its parameters, tuned to the real vocal fold geometry, are provided. The fitting is done in Python 3.8.5 using the scipy.optimize.curve fit package, which contains nonlinear least squares method. It is shown that the augmented M5 model fits the real data with coefficient R2 close to 1 and the tuned parameters are in a good agreement with the overall vocal fold dimensions and with the parameters of the original 2D M5 model.
