talking book
a recorded book distributed in a variety of formats (e.g., CD/DVD, memory card, Internet download) for use by individuals with visual impairment or certain learning disabilities (e.g., dyslexia). Requiring the use of specially designed playback equipment, talking books differ from commercial audiobooks in their use of the Digital Accessible Information SYstem (DAISY), a technical standard with advanced navigation that allows listeners line-by-line access to complex material, such as a textbook, encyclopedia, or periodical. Talking books provide synchronized multimedia files that include audio and text, and they also support braille output.
