Abstract
AbstractCross-language data show that children with dyslexia are poor at recognizing syllable stress patterns, yet their speech production appears normal, suggesting an unexpected disconnect between speech input and output processes. Here we utilized a novel computerized speech copying task based on the speech amplitude envelope (AE) to investigate this disconnect. Seventy-five children with and without dyslexia copied familiar spoken targets like “Aladdin”. Children with dyslexia were significantly worse at producing the multi-syllabic targets as indexed by two similarity metrics for computing the AE. They did not differ from other children in producing the pitch contours of items. Accordingly, impaired AE perception in dyslexia is matched by impaired AE production. Children with dyslexia are heard to produce multi-syllabic words normally because their pitch contours are intact.
