A coupled FE/FV model of self-sustained vocal fold oscillation was presented. The driving pressure differences for the self-sustained oscillation were set up in a natural range. Other material properties were obtained from literature. The form of the oscillating vocal folds could be interpreted as combination of the first three eigenmodes. The second (horizontal) eigenmode eigenmode is of major importance since it is directly affects air jet modulation. The periodically changing convergent and divergent intraglottal shape, that has been reported before, is a combination of eigenmode two and three. To obtain a considerable excitement of these eigenmodes a pulling force (negative pressure) is required which varies its vertical position over time. This force turns out to be dependent of a certain channel length.
