About this trial
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.

Treatments tested in this trial
Seleggo Test
DeviceSeleggo 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.

Trial outcomes
Primary outcomes
1
Reading facilitation (speed), i.e. the advantage in reading performance (speed) produced by personalized parameters as compared to standard parameters
difference between reading speed (seconds to read the text displayed by the software) with personalized and with standard visual parameters
Time frame
Intervention will take place during initial assessment and will last about 1,5 hours (comparison between personalized and standard parameters during the same assessment session)2
Reading facilitation (accuracy), i.e. the advantage in reading performance (accuracy) produced by personalized parameters as compared to standard parameters
difference between reading accuracy (number of errors in reading the text displayed by the software) with personalized and with standard visual parameters
Time frame
Intervention will take place during initial assessment and will last about 1,5 hours (comparison between personalized and standard parameters during the same assessment session)3
Comprehension facilitation, i.e. the advantage in auditory comprehension performance produced by personalized TTS parameters as compared to standard parameters
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
Time frame
Intervention will take place during initial assessment and will last about 1,5 hours (comparison between personalized and standard parameters during the same assessment session)Secondary outcomes
1
possibility to discriminate TD students' reading speed from that of students with DD and SEN
difference (ANOVAs) in performance (in terms of speed, expressed in seconds per syllable) on the reading tests delivered by the software, between the three groups (TD, DD and SEN)
Time frame
about 10 months2
possibility to discriminate TD students's reading accuracy from that of students with DD and SEN
difference (ANOVAs) in performance (in terms of accuracy, expressed in number of errors) on the reading tests delivered by the software, between the three groups (TD, DD and SEN)
Time frame
about 10 months3
possibility to discriminate TD students' writing accuracy from that of students with DD and SEN
difference (ANOVAs) in performance (in terms of accuracy, expressed in number of errors) on the writing tests delivered by the software, between the three groups (TD, DD and SEN)
Time frame
about 10 months4
validity and reliability values for the reading speed measures collected by the software
Pearson's correlations between the speed measures collected during the test and the speed measures obtained on standardized reading tests (MT test of reading speed and accuracy and Assessment Battery for Developmental Reading and Spelling Disorders).
