Sharpness of lateral peaks is a visually helpful clinical feature in high-speed videokymographic (VKG) images indicating vertical phase differences and mucosal waves on the vibrating vocal folds and giving insights into the health and pliability of vocal fold mucosa. Sharp lateral peaks indicate that the mucosa is pliable whereas rounded peaks indicate the mucosa is stiff. This study aims at investigating parameters that can be helpful in objectively quantifying the lateral peak sharpness from the VKG images.
