This is a retrospective of my former work on the acquisition of prosody and specifically the role of the double face of prosody in acquisition is revisited. Also revisited are the notions of discontinuity and continuity by Jakobson and their insuing misinterpretations in the literature in further work on aphasia and phonology acquisition. Finally an approximation of the concepts of continuity/discontinuity and double face of prosody with “double vocation” by Didier-Weill is proposed.
