Figure 7.

(Color online) Forces and configurations at five planes X = 0.6, 0.8, 1.0, 1.2, and 1.4 cm: (a) phase averaged vertical force, (c) phase averaged lateral force, (b) mean and amplitude of vertical force relative to projected area, (d) mean and amplitude of lateral force relative to location, (e) glottal configuration, (f) glottal surface velocity at the X = 0.8 cm plane at the beginning of one vibration cycle. The projected area in (b) is calculated by projecting the subglottal surface area of the vocal fold onto the XZ plane (horizontal plane).
