Advantages and limitations of high-speed digital imaging in studying the singing voice: A critical look
It may be argued that singing requires a greater precision and control of timing and coordination of onset and offset mechanisms, as dictated by the musical score. Another important difference between sung and spoken phonation is the greater frequency range of phonation and control/precision necessary for smoother transition among registers in singing. HSDI has applied advantages in vocal pedagogy, by providing a direct visual example to help better understand the vocal fold (VF) vibratory mechanism during singing. It may also be used as a delayed visual feedback tool.
