In all singers, we measured the length of the VF and of the glottis and the distance of the anterior commissure orthogonally to the vertebral spine and the antero-posterior distance of the trachea 1cm and 2cm below the glottis. [...] The difference between the mean vibratory capability of the vocal folds and the spectrogram of a vowel, the CPP, L/H ratio, SPI and VTI will each be examined separately using a sign test of the paired differences. [...] Results: The four investigated vocal effects could be related to particular and discrete vibratory pattern of supra-glottic structures; Distortion as vibrations of the ventricular folds, Growl as vibrations of the arytenoid cartilages against the epiglottis, Rattle as the vibration of the arytenoid cartilages against one another, and Grunt as the vibrations of the whole supraglottic structure from. [...] Methods: Computer-based patient-inspired models of the blood-supporting arterial vasculature of the human vocal folds were constructed based on our knowledge of the morphology of the major blood-feeding arteries from the computed tomographic angiography (CTA) data available in the literature as well as the reported anatomical data regarding the size and location of the individual branches. [...] We then measured the magnitude, latency, and direction of the reflexive vocal response based on the timing and direction of the perturbation in the phrase.
