A schematic representation of articulatory gestures and audio signal for the syllable /pa/. The aspiration interval, measured as VOT, encompasses the acoustic consequences of supralaryngeal release and vocal fold adduction. In this model, both laryngeal and supralaryngeal gestures are controlled by a stiffness parameter k. The Syllable-Body-Stiffness Hypothesis proposes that the stiffness of both gestures is modulated by upcoming stiffness demands, thereby influencing movement duration and, in turn, aspiration in the syllable onset.
