Using Nyquist-plots definitions and HSDI-based analyses of the acoustic and visual data base of similarly sounding disordered neurologically driven pathological phonations, we categorized these signals and provided an in-depth explanation of how these sounds differ, and how these sounds are generated at the glottic level. Combined evaluations based on modern technology strengthened our knowledge and improved objective guidelines on how to approach clinical diagnosis by ear, significantly aiding the process of differential diagnosis of complex pathological voice qualities in nonlaboratory settings.
