DAISY (Digital Accessible Information SYstem) is a technical standard for digital audiobooks, periodicals and computerized text. DAISY is designed to be a complete audio substitute for print material and is specifically designed for use by people with "print disabilities", including blindness, impaired vision, and dyslexia. Based on the MP3 and XML formats, the DAISY format has advanced features in addition to those of a traditional audio book. Users can search, place bookmarks, precisely navigate line by line, and regulate the speaking speed without distortion. DAISY also provides aurally accessible tables, references and additional information.〔Sabine Tenta: ''The Audible Gate to the World: The West German Audio Book Library for the Blind'' (Goethe-Institut, 2009) (online ) retrieved 26-May-2012〕 As a result, DAISY allows visually impaired listeners to navigate something as complex as an encyclopedia or textbook, otherwise impossible using conventional audio recordings.〔Ask-it: (A5.5.3: Examples of best practices of design for all ). Accessed 2009-11-23.〕 DAISY multimedia can be a book, magazine, newspaper, journal, computerized text or a synchronized presentation of text and audio.〔(DAISY/NISO Standard ). Accessed 2009-11-23.〕 It provides up to six embedded "navigation levels" for content, including embedded objects such as images, graphics, and MathML. In the DAISY standard, navigation is enabled within a sequential and hierarchical structure consisting of (marked-up) text synchronized with audio.〔George Kerscher: "(DAISY is )", December 2003. Accessed 2009-11-23.〕 DAISY 2 was based on XHTML and SMIL.〔DAISY Consortium: (DAISY 2.02 Specification - Recommendation, February 28 2001 ). Accessed 2009-11-23.〕 DAISY 3 is a newer technology, also based on XML, and is standardized as ANSI/NISO Z39.86-2005.〔(ANSI/NISO Z39.86-2005 Specifications for the Digital Talking Book ). Accessed 2009-11-23.〕 The DAISY Consortium was founded in 1996 and consists of international organizations committed to developing equitable access to information for people who have a print disability.〔DAISY Consortium: (About The DAISY Consortium ). Accessed 2009-11-23.〕 The consortium was selected by the National Information Standards Organization (NISO) as the official maintenance agency for the DAISY/NISO Standard.〔DAISY Consortium: (DAISY/NISO Standard ). Accessed 2009-11-23.〕 == Specification == A Digital Talking Book (DTB) is a collection of electronic files arranged to present information to the target population via alternative media, namely, human or synthetic speech, refreshable Braille, or visual display, e.g., large print.
