Vocalization with semi-occluded airways is favorable for optimizing sound production

Expansion of the airway in a simulation model with a 3.0 mm diameter oral semi-occlusion and a lung pressure of 2.5 kPa.
The stiffness of the epilaryngeal airway wall was increased to prevent expansion. (Top) entire airway, and (bottom) glottal and epilaryngeal sections.
