Focus Marking and Prosodic Boundary Strength in French.

Background/Aims: In French, the size of a focus constituent is not reliably marked through pitch accent assignment as in many stress accent languages. While it has been argued that the distribution of lower-level prosodic boundaries plays a role, this is at best a weak cue to focus, leaving open the question of whether other marking strategies are available. In this study, we assess whether the right edge of a contrastive focus constituent is marked by differences in prosodic boundary strength. Methods: We elicited utterances with target words in six combinations of focus and syntactic contexts using an interactive production task. Results: The results show that if a given location is realized as an accentual phrase boundary in an all-focus context, then it is realized as an intermediate phrase boundary when it coincides with the right edge of a narrow-focus constituent. A location that is an intermediate phrase boundary in an all-focus context, however, remains unchanged under narrow focus. Conclusion: These findings suggest that focus constituents are constrained to align with a minimum prosodic domain size in French (i.e., the intermediate phrase), and that French does not rely on a general strategy of prosodic enhancement for marking focus.
