In this article, we explored the pitch contour patterns of the French discourse marker donc in realizing different pragmatic functions from native and non-native oral corpora in French. Statistical analyses using generalized additive mixed modeling revealed that even though Mandarin Chinese L1 speakers learning French also used the pitch cue to realize pragmatic functions, their prosodic pattern is different from the native pattern. Their L1 Chinese seemed to influence their usage of the pitch cue significantly. In addition, women were shown to be better than men in using the pitch cue in conveying pragmatic functions with a closer pattern to the native pattern. Overall, our study sheds new light on the relationship between speakers’ L1 and L2 regarding the interaction between pragmatic and prosodic features. It also provides new reflections on the acquisition of socio-pragmatic competence.
