Articulatory disorders have been occasionally associated with developmental phonological dyslexia. This study used acoustic and aerodynamic data to investigate to what extent developmental dyslexia is associated with potential disorders in the fine-grained control of articulatory movements in voiced and voiceless bilabial stops /b/ and /p/ production in a repetition task. Our results reveal more deviations from the target consonant for the dyslexic than for the control. This study shows also differences in the timing of the articulatory movements between dyslexics and controls. These observations are consistent with recent findings pointing to a general deficit in fine motor control in dyslexia.
