They empower users to hear content and navigate with the keyboard. The technology helps people who are blind or who have low vision to use information technology with the same level of independence and privacy as anyone else. Screen readers are also used by people with certain cognitive or learning disabilities, or users who simply prefer audio content over text.
Screen readers read content differently from humans. The voice may sound somewhat robotic and monotone. Experienced users often like to speed up the reading rate to words per minute or more—well beyond what an inexperienced listener can easily understand.
It takes time to get used to a screen reader, but once users become accustomed to it, they can race through content at speeds that awe sighted individuals. This also facilitates automatic translation of content.
See full list of lang codes. Sometimes text is interspersed with foreign phrases. This flags a temporary departure from the previously-specified document language.
The Cost of an Incorrect lang Attribute When text in one language is read with the pronunciation rules of another, the result approaches a comically-thick accent. Here is a passage of text in English. Most people today can hardly conceive of life without the Internet.
Your browser does not support the audio element. The lang attribute can be applied to nearly any HTML element. Although it makes no visual changes in itself, it does provide a convenient hook for CSS. A common convention shared by this website is to italicize foreign phrases.
CSS handles this easily: Alternatively, it can all be done in HTML, like this: Content Linearization Audio interfaces present content linearly to users, one item at a time. This contrasts with the way in which most people use visual interfaces.
Sighted users can scan an entire screen almost instantaneously, comprehending the overall layout, the artistic style, and other macro-level aspects of the content.
Screen reader users cannot comprehend these macro-level aspects as quickly. The linear progression through the content from beginning to end is somewhat like automated telephone menu systems which do not reveal all of the options at once.
Users must progress through such systems in a step-wise manner. The insight that audio interfaces are linearized versions of web content is an important one that should guide web developers during the engineering and design process.
Navigating Content Despite the linear nature of audio interfaces, screen readers do provide ways for users to navigate content quickly.
Links and Form Controls One way is to use the Tab key to jump from link to link. This gives the user an idea of where the page links to, and can be a useful way to run through the content if the user is looking for a specific link. A related technique is to obtain a list of the links on the page, arranged alphabetically.
The drawback of these methods is that the user does not hear any of the non-link content, and may miss important information this way.
Links should make sense when read out of context. Headings Another way to get an overall impression of a page's content is to jump from heading to heading. Users can hear an outline of the page's main ideas, then backtrack to read the parts they are most interested in. The main drawback to this technique is that it relies on headings—which too many pages lack.
Authors should organize content with headings. To the extent possible, the headings should represent an accurate outline of the content. Paragraphs and page elements Users can jump from paragraph to paragraph, listening to the first sentence or two before moving on to the next paragraph.
This technique resembles the way visual users explore the page before focusing on an area of interest.Among science fiction stories with space flight, the overwhelming majority are about combat, both between spacecraft and between futuristic ground troops. "Modern man perceives time as a linear progression, with a fixed past, present, and future.
The Maya, on the other hand, understood time as something more fluid and they believed that periods of time would be repeated through a series of world ages. Ten Areas of Technological Change, John Smart, A read ahead in technological change, for senior leaders and middle managers.
