Laryngeal and vibroacoustic factors in Estill voice model figures – case study

Popis výsledku v původním jazyce

Laryngeal dimensions and glottal and acoustic parameters were measured in a single female subject who performed 7 out of 13 voice figures and 6 qualities from Estill Voice Training (EVT). High speed videolaryngoscopy and acoustic analysis showed that the influence of voice figures and qualities on vocal fold oscillations was significant. Factor analysis identified the glottal behavior in open and closing quotients and glottal stiffness as significant factors, which mainly describe body cover control figures. The second type of interpretable factor of vocal fold oscillation was related to the speed quotient; therefore changes in the degree of adduction as well as acoustic interaction between the vocal folds and the supraglottal vocal tract could be assumed. With the exception of the second formant, which was related to the vertical position of the larynx and tongue, changes in acoustic features were mainly manifested in the total SPL. This was primarily influenced by the level of the first harmonic component and secondly by the energy in the 2 - 4 kHz bandwidth.
