Personalizace vizuálních postav a textu na řeč (TTS) na podporu učení u studentů s obtížemi čtení

3. listopadu 2026 aktualizováno: IRCCS Eugenio Medea

Účinnost personalizace vizuálních parametrů a textu na řeč ke zlepšení rychlosti čtení, přesnosti a porozumění u studentů s poruchami učení

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.

Detailní popis

Seleggo is a free compensatory tool for dyslexic students. It is an online platform where school textbooks are transcribed and visualized on the screen in portable format (PDF) versions, characterized by special attention to graphical features and readability, and can be listened to via TTS technology. Special functions such as karaoke modality, conceptual maps building software, summary creation, verbal and visual definition search and the possibility to record and retrieve one's own notes and sketches are also provided. Each student with Specific learning Disorder (SLD) has a personal library and can choose the parameters for text visualization to facilitate reading, modifying the display of the text, choosing font, size and spacing, as well as TTS parameters, such as speed and pitch.

The availability of many options for text visualization and TTS, however, can be advantageous only as far as the students are able to choose and use parameters that objectively facilitate their reading and comprehension. Since the analysis of the literature suggests that subjective choices may be misleading and that general recommendations may not fit the individual's needs, we decided to build an automatized, as objective as possible procedure to help the students find the combination of parameters that is most likely to facilitate them in reading and studying. This procedure, composed by an initial, gross-grained subjective procedure and followed by a thorough, systematic analysis of reading and comprehension performance, was named "Seleggo test" to match the compensatory tool it was meant to complement.

The present study aims to assess the actual advantage of personalized parameter selection through the "Seleggo Test" procedure in supporting reading compared to the use of standard parameters. The working hypothesis is that children with reading disorders would benefit from personalized text features and TTS.

The recruitment of participants will take place in schools. It is foreseen that 30 participants are recruited for each of the three groups: typically Developing children (TD), Developmental Dyslexia (DD) and Special Educational Needs (SEN) - with reading difficulties).

Additional children will be recruited form patients with DD at Scientific Institute (IRCCS) E. Medea, if necessary to reach the expected number. Children will attend the third grade of primary school to the third grade of middle school (7 to 15 years old).

Experimentální: Participant

All participants in the study will be assessed with the Seleggo Test procedure and then tested on reading and writing to dictation in the two conditions, with personalized and with standard visual and auditory parameters for text visualization and TTS

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.
