Scientific objectives

Linguistic models of the functioning of language have traditionally been based on linguistic examples obtained in controlled situations, quite far from the reality of everyday language. In the last decade, new work has sought to describe language in a more natural context, and in particular that of conversation. These studies focused on descriptions concerning several linguistic domains as well as their interactions: phonetics, prosody, syntax, semantics, pragmatics, mimo-gestural.

In this context, the team’s project aims to develop a language model placing interaction at the heart of the question of linguistic structures. In our approach, conversational interactions are further described in close relation to the way in which language is processed in the speaker’s brain. To meet this objective, several central themes will be addressed. In continuity with the project of the previous five-year period, it will be:

(1) To study phenomena appearing specifically during an interaction between speakers (eg. backchannels, imitation and convergence at the phonetic and discursive levels), in order to analyze the interaction between the different linguistic domains and to understand which linguistic units ( eg. prosodic, syntactic, mimo-gestural units) are the most relevant to reflect these interactions.

(2) To broaden our knowledge of how language and communicative activities are characterized by the interaction situation.

(3) To develop tools and methods for the analysis, exploration and annotation of mono- or multimodal data. This involves two complementary movements.

July 8, 2020: Roxane Bertrand and Noël Nguyen, two members of the Interactions team, have just published an article in “The Conversation France”. Entitled “The Complex Mechanics of Ordinary Conversation” (article in French), the article sheds light on the mechanisms and practices of oral conversation.
