Definition: Defining the Meaning of Screen Reader

A screen reader is defined as a software application that attempts to identify and interpret what is being displayed on a computer screen. This interpretation is then re-presented to the user with text-to-speech, sound icons, or a Braille output device. Screen readers are a form of assistive technology (AT) potentially useful to people who are blind, visually impaired, illiterate or learning disabled, often in combination with other AT, such as screen magnifiers. Computer screen readers read out loud the content that is on the computer screen. Screen readers enable access to a computer and all the things it does when magnification no longer helps or when you might experience visual fatigue if you have to read large amounts of on-screen text.

Main Document

A screen reader is a software application that attempts to identify and interpret what is being displayed on the computer screen.

This interpretation is then represented to the user with text-to-speech, sound icons, or a braille output. Screen readers are a form of assistive technology (AT) potentially useful to people who are blind, visually impaired, or learning disabled, often in combination with other AT such as screen magnifiers.

Some programs speak or make other sounds so that they can be used by blind people or people who cannot see the screen. These programs are termed self-voicing and can be a form of assistive technology if they are designed to remove the need to use a screen reader.

Not only do screen readers differ widely from each other, but most are highly configurable. For example, most screen readers allow the user to select whether most punctuation is announced or silently ignored. Some screen readers can be tailored to a particular application through scripting. One advantage of scripting is that it allows customizations to be shared among users, increasing accessibility for all. JAWS enjoys an active script-sharing community, for example.

Microsoft Windows operating systems have included the Microsoft Narrator light-duty screen reader since Windows 2000.

Apple Inc. Mac OS X includes VoiceOver, a feature-rich screen reader. (List of VoiceOver Apps)

The console-based Oralux Linux distribution ships with three console screen-reading environments:

  • Emacspeak
  • Yasr
  • Speakup

BlackBerry 10 devices such as the BlackBerry Z30 include a built-in screen reader. There is also a free screen reader application for older less powerful BlackBerry (BBOS7 & earlier) devices.

The most widely used screen readers are separate commercial products:

  • JAWS from Freedom Scientific
  • Window-Eyes from GW Micro
  • Dolphin Supernova by Dolphin
  • System Access from Serotek
  • ZoomText Magnifier/Reader from AiSquared
  • The opensource screen reader NVDA is gaining popularity.
Screen readers that are free and/or offer a free trial period and can be purchased online.

Facts: Online Document Accessibility

  • In Australia the Human Rights and Equal Opportunity Commission (HREOC), takes the official position that posting a document online only as a PDF is inaccessible, hence a violation of the Disability Discrimination Act.
  • The WCAG sets the standards for web content to insure that it is accessible to people with disabilities. This set of guidelines is directed towards web content developers.
  • An accessible online document has an established reading order, as well as visual elements that are tagged with alternative text descriptions.
  • To comply with the Americans with Disabilities Act (ADA), documents posted online, including, but not limited to, Adobe PDF files, Microsoft Word documents, Microsoft PowerPoint presentations, and online flipbooks, must be screen-reader friendly.
  • A properly built web site is, by default, screen reader and, as such, also search engine friendly.
