Research Abstract |
In this research project, we revealed production mechanisms of ab- and supra normal phonations using physiological observations, such as high-speed digital recordings of vocal fold vibrations, and physical simulations. We proposed and implemented a laryngo-topography which is a method for modal analysis of vocal fold vibrations, and 3-dimensional measurements of vocal fold vibrations using stereographic high-speed digital imaging. We also proposed and implemented a new method for synthesis of subharmonic voices based on physiological observations.
