Current high-speed digital imaging (HSDI) allows thousands of images per second to be obtained, hence it provides significant information on the behavior of the vocal folds (VF) during phonation. Here we present our findings of glottis behavior for normal and exaggerated phonatory modes studied with HSDI, acoustics, and EGG.
