Artificial System of Ex Vivo Animation of the Larynx

The human voice has an extremely variable range of acoustic characteristics depending on whether it is a whispered, sung, spoken or pathologically effected voice. To produce these different types of voices, humans use the length of the vocal folds and their level of contact (delineating the glottis).

Our project develops a mechanized system of ex vivo animation for human larynxes excised post-mortem. Following measures taken in vivo of the dynamic (amplitude and speed) of the glottis’ movements, we aim to reproduce them via an artificial mechanical controller.
