Many National Blindness Libraries use Dolphin Publisher to professionally produce digital talking books, making titles fully accessible to readers with vision and print impairments. Libraries are now ready for the future of accessible eBook production with Dolphin Publisher's support for human-narrated EPUB 3 with media overlays.

"The EPUB 3 standard empowers publishers to create fully accessible text and audio content in a mainstream digital format" explains Mattias Karlsson, AltFormat Product Manager at Dolphin. "The addition of EPUB 3 support in Dolphin Publisher continues Dolphin's commitment to enabling digital libraries to fully engage readers with vision and print impairments with professionally produced, human-narrated eBooks"

With the ability to add 'media overlays' for synchronized audio and text, EPUB 3 is set to become the de-facto accessible digital book format. Digital libraries using Dolphin Publisher 3.50 can now create EPUB 3 books using either a human sounding synthetic voice, or human-narrated audio.
