Évaluation contextuelle de la (dis)fluence en production et perception : pratiques communicatives et formes prosodico‐syntaxiques en français

Abstract

The objective of this thesis is to study the effects of (dis)fluencies on the production and perception of speech by French native speakers. The ease at which we produce, perceive and interpret spoken language depends on various linguistic, situational and social factors. Hence, the way one defines "fluency" or "disfluency" itself depends on which type of context is taken into account, and more precisely, on what kind of expectations one draws from this context. (Dis)fluencies are linguistic devices such as silent and filled pauses, vocalic lengthening, lexical repetitions or discourse markers (e.g. well, you know, I mean). The main hypothesis of this research is that not all (dis)fluencies are equal and that some of them may participate in the evaluation of fluency. Hence, their ambivalent status can either support or hinder the production and perception of speech in interaction. These analyses specifically target the definition of linguistic, situational and social expectations of disfluencies and discourse structure, by observing the variability and homogeneity of discourses across various situations. The method combines statistical and quantitative analyses of annotated corpora and perception experiments. Each chapter is devoted to one phenomenon (silent pauses, filled pauses, lengthening and repetitions). Linguistic or contextual disfluency is considered when there is a mismatch between expectations and the produced/perceived content in context, potentially creating discursive rupture.(LALE - Langues et lettres) -- UCL, 201
