This contribution deals with anticipatory modelling during pausing in clear speech, through a set of production and perception experiments performed in the frame of the "silent pause paradigm" for vowel-to-vowel gestures. A new model, first developed classically on upper lip protrusion behaviour for [i]-to-[y] rounding gestures through consonants, then extended to lip constriction, the MEM (Movement Expansion Model), is tested in pausing both for (i) rounding and (ii) for vowel [i]-to-[a] height gestures, (i) This procedure allows to "substract", when it occurs, consonantal influence in the building up phase of the rounding constriction, (ii) Expansion of the opening phase is also evidenced for height dimensions. Beside its advantages, this "silent pause paradigm" introduces more directly, than juncture through consonants, to articulatory prosody of pause control, as reflected in movement time, amplitude and peak velocity, for the two main vowel visible gestures.
