In search of cues discriminating West-african accents in French

International audienceThis study investigates to what extent West-African French accents can be distinguished, based on recordings made in Burkina Faso, Ivory Coast, Mali and Senegal. First, a perceptual experiment was conducted, suggesting that these accents are well identified by West-African listeners (especially the Senegal and Ivory Coast accents). Second, prosodic and segmental cues were studied by using speech processing methods such as automatic phoneme alignment. Results show that the Senegal accent (with a tendency toward word-initial stress followed by a falling pitch movement) and the Ivory Coast accent (with a tendency to delete/vocalise the /R/ consonant) are most distinct from standard French and among the West-African accents under investigation
