As an initial step towards self-training of dyslexics, this paper presents the overall design- and usability evaluation results of a simulated reading training system for dyslexics that uses ASR and multi modal presentation techniques as core components. Based on an analysis of dyslexic reading behaviour as well as extensive usability evaluations involving actual dyslexic test subjects it is indicated that current ASR performance in fact suffices for dealing with dyslexic input to an automated training system when the special phenomena present in dyslexic speech are taken into account. Finally, explicit design guidelines for such a system are derived experimentally aiming at assuring a high level of perceived usability when used by dyslexic users.
