In this paper, the application of the Equilibrium Point Hypothesis originally proposed by Feldman for the control of limb movements to speech control is analysed. In the first part, physiological data published in the literature which argue in favour of such control for the tongue are presented and the possible role of this motor process in a global control model of the tongue is explicated. In the second part, using the example of the acoustic variability associated with vowel reduction, we focus on how the Equilibrium Point Hypothesis could help to search for physical regularities associated with a phonological sequence produced under variable speech conditions: the equilibrium point sequence could be invariant while the level of cocontraction and the timing of the commands could vary with the speech condition.
