Gesture meaning needs speech meaning to denote – A case of speech-gesture meaning interaction

We deal with a yet untreated issue in debates about linguistic interaction, namely a particular multi-modal dimension of meaning-dependence. We argue that the shape interpretation of speech-accompanying iconic gestures is dependent on its co-occurrent speech. Since there is no prototypical solution for modeling such a dependence, we offer an approach to compute a gesture’s meaning as a function of its speech context
