Abstrakt: An inverse method was used to estimate the vocal tract geometry as a 1D model on the basis of acoustical characteristics of a professional musical singer before and after vocal exercising. The basic geometrical data for the model were obtained from MRI registered during sustained phonation of vowels [a:], [i:], [u:] produced in naive and professional ways. The model was used for numerical simulations of the voice signals. The results of simulation were compared to the acoustic recordings. According to the results, a singer’s formant cluster was accomplished after exercising. It seemed to be due to lowering of the larynx and lengthening and narrowing of the epilarynx. There was a qualitative agreement between 3D measurements of MRI and the results of modeling. The results suggest that for a singer’s formant cluster a relatively low pharynx over epilarynx ratio may be sufficient, at least if the larynx lowers.
Klíčová slova: acoustic effects of vocal exercises; biomechanics of voice; singer’s and speaker’s formant cluster
