For students with dyslexia or other reading or writing difficulties, it is a good help for them to use a reading guide. The reading guide helps the student to stay focused on the correct sentence.
In Trelson the reading guide works only on the attached PDF. The student can enable and disable the reading guide by clicking on the reading guide icon in the upper right corner.
To activate the reading guide, when uploading the PDF, the file needs to be converted to support text to speech. This is done by selecting the checkbox next to the file.
