Abstract
Vocalis muscle and vocal ligament are modeled separately, each by a row of eight masses, with 2 degrees of freedom per mass. This allows for motions in the direction of the flow and transverse to the flow. Vertical phasing at low pitches and horizontal phasing at high pitches are demonstrated. Parameters, which can be adjusted at liberty, are cord elasticity, ligament tension, vocalis tension during contraction, subglottal pressure, and the cord boundary. The variable boundary is employed to allow for various statically strained conditions, such as medial compression and open chink. The normal modes of the system are seen by applying either a sudden burst of pressure (such as in a cough) or by displacing one or several of the masses and allowing the motion to come to rest. Chest, middle, and high registers are demonstrated, including a register transition.
