Jan Švec - How is the human voice created?

Dr. Jan Švec from the Biophysics Department of Science Faculty of Palacky University in Olomouc will present a lecture on how a human voice.

The human voice originates from air traveling from the lungs through closed vocal cords that begin to vibrate due to passing air. The vocal cord's vibrations cause a rarefaction and a compression of passing air, creating primal sound. This initial sound does not have all characteristics of a human voice. Those will be created by passing through resonance cavities above the vocal cords (larynx, pharynx, oral and nasal cavities). These cavities amplify some of the frequencies of the primal sound due to their resonance capabilities. The resulting voice carries information about the vocal cords' vibrations and the resonance cavities of each individual. It is possible to distinguish people by their voice since each of us has vocal cords and cavities slightly different.

In this lecture, the speaker will present the basic principles of human voice creation. The knowledge to successfully understand the creation of the human voice comes from information from many scientific fields.
