 This study examined the differences between the vocal patterns of individuals with adductors spasmodic dysphonia, ADSD, and those without the condition. It found that the vocal patterns of individuals with ADSD differed significantly from those without the condition, with the former having longer glottal attack times and shorter glottal offset times. These differences could potentially be used as objective markers to identify ADSD. This article was authored by Mariam Nagabal-Hassini, Stephanie R. C. Zacharias, Serizinas, and others.
