Definition: DTBook

(Digital Talking BOOK) An electronic publishing format for people who cannot access a book due to a visual, mental or physical impairment from The DAISY (Digital Accessible Information System) Consortium, Zurich, Switzerland (www.daisy.org).

Superior to continuous analog voice recordings, DTBooks provide users with an eyes-free reading experience and still be able to skim and bookmark interesting passages. Based on the XML and SMIL standards, DTBooks use a navigation system, digitized audio files and additional human narration to allow people to move from page to page and chapter to chapter. DTBooks can be read on a portable playback device or a computer with DAISY software. See XML and SMIL.
