Yes. Built with Readium’s rendering engine, the Open eBooks App takes advantage of the accessibility features that are native to the EPUB3 format in which the books are rendered. Open eBooks is compatible with Apple and Android’s Text to Speech (TTS). In the future we plan to improve the implementation of Readium to make this even more robust.
We're working on improving the experience and accessibility in future updates and versions of the app and its content. Again, making this content accessible is a top priority and we are working with all our industry partners to make progress in this area.
We also encourage families, teachers and librarians of readers with print disabilities to try applications like BARD, BookShare, and Learning Ally. These great resources can help students build an even bigger collection of eBooks.
