Czech Scientist Invents World's First Artificial Vocal Chords

The invention by Czech scientist Vojtech Misut from the Technological University in Brno can return voice to those who have lost it in the surgery. However, in spite of the success, the development of artificial chords is yet at the beginning. A suitable material, dimensions, shape as well as placement are yet to be found.

Misut first created a computer model of the vocal chords according to his own theory, and now he has successfully tested his physical model as well.

Since the vocal chords differ by length, Misut had to create special models for men, women and children that can be shaped so that people even recognise their lost voice.

Misut is not yet able to implant the artificial vocal chord in its original place in the patient's throat.

That is why air is conducted from the lungs through a tiny tube to the artificial vocal chord fixed for instance to the chest. The created source voice is led by the tube back to the voice tract where it is fine-tuned.

Misut is considering placing the artificial vocal chord in the nasal cavity.
