Insufficient accessibility support. EPUB is well-aligned with the DAISY standard but does not presently incorporate all DAISY features; in particular, there is not explicit support for full synchronization of multiple media types, such as audio and text. The proposed EPUB 2.1 revision will coincide in time with the revision of DAISY (ANSI/NISO Z39.86); the option to further the harmonization of the two standards should be considered.

Has somebody come up with a working workaround for synchronizing audio and text in the current EPUB standard? I haven't bumbed into an EPUB with text-to-speech feature. I would like to do an e-book with audio synchronized to text but I guess I just need to wait for EPUB 3 standard.
I'm really looking forward that SMIL (Synchronized Multimedia Integration Language) will be supported by EPUB 3. Do you think reading devices will be able have support for this feature in the EPUB 3 standard? I guess new devices will be but are the companies willing to do firmware updates for older reading devices for full EPUB 3 support. I doubt but I hope so.
Here's a link how SMIL is used in EPUB 3 standard: http://idpf.org/epub/30/spec/epub30-mediaoverlays.html
