Convey structure • Structure implicit in page layout • Annotations • Keywords • Voice characteristics • Beeps between paragraphs SectionSome people must be provided with alternative access to the power of the written word. The blind are unable to read conventional books. People with dyslexia or other reading disabilities have trouble efficiently decoding the written word. Even people without a disability could benefit from an alternative to reading material; for example, when riding the bus, instead of reading they could listen to the text, as an audiotext. A computer system enables a person to access audiotexts, which give similar information as from reading conventional books. beep Audio versions of text must provide a literal reading and also convey the text’s structure. Text structure conveys meaning. Comprehension of writing comes from understanding a series of independent consecutive points. Sections or chapters represent different parts of a document’s main idea. Furthermore paragraphs are sub-points of the idea expressed in a section. In printed material, the format of section headings and whitespace between paragraphs implicitly indicates the transition between individual ideas. Similar format information must also be conveyed in audiotexts. beep
