Evaluation of Analytical Modeling Functions for the Phonation Onset Process

Left: image series of hs recordings of vocal folds; middle: single hs image of vocal folds with segmented glottis—blue area; right: function of the glottal area waveform (GAW) derived from the segmented image series over time (i.e., image series). Maxima in the GAW correspond to an open glottis and zero values to a closed glottis.
