Prosodic effects on L2 French vowels: a corpus-based investigation

Abstract : We examine the effects of prosodic strengthening on the acoustic realization of L2 French oral vowels. We analyse 12,283 vowels produced by 20 learners of French (L1 Spanish and English) and 10 native speakers according to different prosodic positions: (i) IP-final (ii) AP-final (obligatory accent) or AP-initial (initial non-obligatory accent) and (iii) word-internal unaccented. We computed the convex hull area of F1/F2 and F2/F3 spaces, Euclidean distances and vowel durations. Results show that the L2 vowel space is expanded in strong prosodic positions. Differently from what we observe for native French speakers, vowel expansion does not consistently reflect the prosodic hierarchy for the two groups of learners. We discuss these results in the light of L2 acquisition phonology.
