Lectal Coherence in Conversation – Modelling Intra- and Inter-situational Language Behavior

Lucie Flek (University of Bonn), Alfred Lameli (University of Marburg)

This project investigates lectal coherence as a dynamic phenomenon emerging from speakers’ spontaneous linguistic decisions in interaction. Using conversational data from the REDE corpus, it explores how dialectal, standard, and mixed variants co-occur, how situational, interactional, and individual factors shape these patterns, and how coherence trajectories evolve in real time. Combining sociolinguistic analysis with AI-based modelling, the project links micro-level speech behaviour to macro-level language variation and change.
