DAISY

An international standard and consortium dedicated to making published information accessible to people with print disabilities including blindness, low vision, dyslexia, and physical disabilities that prevent handling books. The DAISY standard defines a format for creating structured, navigable digital talking books with synchronized text and audio. The DAISY Consortium played a key role in merging accessibility requirements into the mainstream EPUB standard, and DAISY 4 (the latest version) is technically aligned with EPUB 3. The consortium also develops tools for accessible publishing including the ACE accessibility checker for EPUB and the DAISY Pipeline for format conversion.
