Personalization of Visual Characters and Text-to-Speech (TTS) to Support Learning in Students With Reading Difficulties

Condition(s) studied

Investigational drug(s) / intervention(s)

Seleggo Test: Seleggo Test is a computerized procedure to identify the personalized visual and auditory parameters facilitating reading and writing for each participant. By applying these parameters to the visualization and to the TTS software during reading of school texts, the participants are expected to be facilitated in reading and understanding the text.

Study summary

Previous research has shown the importance of font type, size and spacing to facilitate text reading in dyslexia. A special automatized procedure was designed to select the most favorable parameters for both text visualization and text-to-speech (TTS) conversion to be used by students with reading difficulties. The validation of its outcomes will be carried out through a systematic comparison of the use of the personalized versus standard fonts and voices in reading and writing tests.

Eligibility

Primary outcome measure(s)

• Reading facilitation (speed), i.e. the advantage in reading performance (speed) produced by personalized parameters as compared to standard parameters — Intervention will take place at day 1 assessment and will last about 1,5 hours (comparison between personalized and standard parameters during the same assessment session)
  difference between reading speed (seconds to read the text displayed by the software) with personalized and with standard visual parameters
• Reading facilitation (accuracy), i.e. the advantage in reading performance (accuracy) produced by personalized parameters as compared to standard parameters — Intervention will take place at day 1 assessment and will last about 1,5 hours (comparison between personalized and standard parameters during the same assessment session)
  difference between reading accuracy (number of errors in reading the text displayed by the software) with personalized and with standard visual parameters
• Comprehension facilitation, i.e. the advantage in auditory comprehension performance produced by personalized TTS parameters as compared to standard parameters — Intervention will take place at day 1 assessment and will last about 1,5 hours (comparison between personalized and standard parameters during the same assessment session)
  difference between writing accuracy (number of errors in writing a pre-defined list of nonwords) for stimuli dictated with personalized and with standard auditory parameters in the TTS device
