Choosing an E-Text Format
PDF and DOC
PDF’s are a great visual aide for students with LD or who are hard of hearing. The DOC files will be more useful to a student who is blind. The type of e-text format provides different accessible options and is based on a number of factors.
Those factors are based on:
- The Subject Matter being converted
- The Formating of the book being processed
- The Assistive Technology used
- Personal Preference.

EPUB is the distribution and interchange format standard for digital publications and documents based on Web Standards. EPUB defines a means of representing, packaging and encoding structured and semantically enhanced Web content — including XHTML, CSS, SVG, images, and other resources — for distribution in a single-file format. EPUB allows publishers to produce and send a single digital publication file through distribution and offers consumers interoperability between software/hardware for unencrypted reflowable digital books and other publications.
DAISY denotes Digital Accessible Information SYstem. The DAISY Consortium is committed to making the transition from analog (print and tape) to Digital Talking Books (DTB). The idea is to use digital recording and add document structuring that would allow easy navigation by the user.
- One or more digital audio files containing a human narration of part or all of the source text;
- A marked-up file containing some or all of the text (strictly speaking, this marked-up text file is optional);
- A synchronization file to relate markings in the text file with time points in the audio file; and
- A navigation control file which enables the user to move smoothly between files while synchronization between text and audio is maintained.
The DAISY Standard allows the producing agency full flexibility regarding the mix of text and audio ranging from audio-only, to full text and audio, to text-only.
Some screen reader programs allow text to be output to an audio file (usually MP3 or WAV) which can then be imported to an audio player on a computer such as Windows Media Player or iTunes, transfered to a portable audio device such as an iPod, or burned to a compact disc. The drawback to this format is that these standard audio files have none of the navigation features of a DAISY book or a screen reader program.
Braille is a series of raised dots that can be read with the fingers by people who are blind or whose eyesight is not sufficient for reading printed material. Teachers, parents, and others who are not visually impaired ordinarily read braille with their eyes. Braille is not a language. Rather, it is a code by which languages such as English or Spanish may be written and read. 
Captions & Subtitles
Closed Captioning Captions vs. Subtitles Captions and subtitles display audio information as printed words on the viewing screen. Subtitles present only the spoken word whereas captions are specifically designed for viewers who are deaf and hard of hearing and are carefully placed to identify speakers, on- and offscreen sound effects, music, and laughter.
