This paper aims to investigate whether--and how--consonant sonority (obstruent vs. sonorant) and status (coda vs. onset) within syllable boundaries modulate the syllable-based segmentation strategies. Here, it is questioned whether French dyslexic children, who experience acoustic-phonetic (i.e., voicing) and phonological impairments, are sensitive to an optimal "sonorant coda-obstruent onset" sonority profile as a cue for a syllable-based segmentation. To examine these questions, we used a modified version of the illusory conjunction paradigm with French dyslexic children compared with both chronological age-matched and reading level-matched controls. Our results first showed that the syllable-based segmentation is developmentally constrained in visual identification: in normally reading children, it appears to progressively increase as reading skills increase. However, surprisingly, our results also showed that dyslexic children were able to use syllable-sized units. Then, data highlighted that a syllable-based segmentation in visual identification basically relies on an optimal "sonorant coda-obstruent onset" sonority profile rather than on phonological and orthographic statistical properties in normally reading children as well as, surprisingly, in dyslexic children. Our results are discussed to support a sonority-modulated prelexical role of syllable-sized units in visual identification in French, even in dyslexic children who exhibited a developmentally delayed profile. We argue that dyslexic children have deficits in online phonetic-phonological processing rather than degraded or underspecified phonetic-phonological representations.
