In this study we investigate voice productions of normal speakers and patients with varying vocal fold adduction deficiencies using a noninvasive method to measure spatial vibrations of the larynx. The current version accv4 of our acceleration sensor device was used. The study's primary goal is to find out whether lesions of vocal folds lead to additional spatial vibration modes compared to a non-disordered voice. Our results allow to assume that the composition of spatial vibration modes at the skin over the cricothyroid ligament may depend on the symmetry of vocal fold movements.
