Anotace	Unilateral paralysis of the superior laryngeal nerve affecting the cricothyroid muscle produces an imbalance in the longitudinal tension of the vocal folds during phonation. Such an asymmetry causes changes in the vibratory pattern of the vocal folds and in the resulting voice quality. This problem was studied using the synthetic, three-layer, life-size vocal fold model joined to the simplified model of lungs and to the plexiglass model of the human vocal tract. Fluctuations of the subglottal (tracheal) and oral pressure were recorded synchronously with the signal from the high-speed camera to analyse vocal folds vibrations. The vibration pattern resembles pathological asymmetric vibration patterns observed in vivo in patients with unilateral vocal fold paralysis. The period irregularities on both the vocal folds are typical for rough or diplophonic voices.
