LEX is an Android-based voorleesapp developed by Stichting Dedicon, a non-profit organization that provides accessible reading materials for people with reading disabilities. The app helps students with dyslexia or visual impairments listen to their school textbooks, which are spoken by a human voice. LEX eliminates the need for a laptop or Daisy player to listen to Dedicon's educational books, making it a convenient solution for both home and classroom use.

To access the spoken textbooks for LEX, users must order them from the Dedicon Educational webshop. The books are offered via streaming, but users can download them to their mobile devices for offline use. The app also allows for easy navigation through the books, with the ability to jump to desired chapters and pages, add bookmarks, and adjust reading speed.

One of the most convenient features of LEX is the ability to play the textbook in background mode, allowing students to listen while using other apps. The app is fully accessible via VoiceOver functionality and has simple controls for easy use.

For those interested in trying out LEX, a free demo account is available for users to experiment with the app and access four spoken sample books. Overall, LEX is a useful tool for students with reading disabilities, providing an accessible and convenient way to access educational material.
