From multi-dialogue to monologue in spoken Italian: the pragmatic/prosodic basis of multi-dialogue and its transformation in narrative and descriptive monologues – The paper summarizes the Language into Act Theory (L-AcT), according to which spoken texts are analysed and aligned per utterance to the acoustic source. Three stretches of spoken Italian taken from the LABLITA Corpus (multi-dialogue, dialogue, monologue) are described according to L-AcT as regards turn-taking, information structure, and illocution. The above texts are then compared to a short literary excerpt showing the different syntactic architecture of the two language varieties.
