- Résumé : The general auditory deficit in temporal processing is one of the main views still debated to explain nature and origin of dyslexia. In our study, we investigated the auditory temporal processing in expert readers and in dyslexics adults. By time-compression of rapid acoustic features, we explored their abilities of extraction and analyse of this cues (Experiment 1: voice onset-time and Experiment 2: second formant transition). Compared with controls, dyslexics exhibit deficit in temporal processing and the impairment is stronger for voicing than for formant transition. A distinct temporal processing for both acoustic features and mechanisms of compensation, have been observed for dyslexics.
