Jaws is primarily designed for desktop computers, but they also offer a portable USB pen drive version. Jaws is developed by Freedom Scientific, market leaders in screen reader technology. Voice Over uses the Cepstral TTS by default. Instead of requiring a separate application to be purchased, Voice Over comes as part of the MacOSx Tiger OS.

MAC OS screen readersДЄpple took a new approach to screen reader technology. Both of these Linux screen readers follow the open source tradition, which means they are freely available for download.

The Speakup project developed the Speakup screen reader which can be run on some of the popular Linux distributions, including Debian and Slackware. It enables visually impaired computer users to access the Gnome 2 desktop. The Gnopernicus screen reader is developed by Sun MicroSystemвЂ™s Gnome Accessibility Project. Screen readers are available for each of the most common operating systems, Linux, Mac OS and Windows. Which operating systems do screen readers work with?

Each screen reader uses a different series of commands, so most people will tend to choose a screen reader and stick with it, as the task of learning a large number of new keyboard commands is considerable. An example of a Microsoft Windows keyboard shortcut is using the alt + A key combination to open the Favourites menu in Internet Explorer. A visually impaired computer user will use a combination of screen reader commands and operating system commands to accomplish the many tasks a computer is capable of performing.ДЄll current operating systems have their own keyboard shortcuts, which are available to everyone not just screen reader users. Tasks include reading part or whole of a document, navigating web pages, opening and closing files, editing and listening to music. Since the majority of users donвЂ™t use a mouse, all screen readers use a wide variety of keyboard commands to carry out different tasks. Whilst it is possible to use either format independently, Braille output is commonly used in conjunction with speech output. Each cell can be formed into the shape of a Braille character, a series of dots that are similar to domino dots in their layout.ДЄs the information on the computer screen changes, so does the Braille characters on the display change, providing refreshable information directly from the computer. A refreshable Braille display contains one or more rows of cells. An external hardware device, known as a refreshable Braille display is needed for this. In addition to speech feedback, screen readers are also capable of providing information in Braille. Originally, before computers had soundcards, screen readers always used hardware TTS devices, but now that soundcards come as standard on all computers many find that a software TTS is preferable. A TTS may be a software application that comes bundled with the screen reader, or it may be a hardware device that plugs into the computer.

There are two ways that this hardware can provide feedback to the user:ДЄ screen reader uses a Text-To-Speech (TTS) engine to translate on-screen information into speech, which can be heard through earphones or speakers.

How does a screen reader relay information to the user? The device provides access to the entire OS that it works with, including many common applications. Screen readers work closely with the computerвЂ™s Operating System (OS) to provide information about icons, menus, dialogue boxes, files and folders.

A screen reader is a software application that enables people with severe visual impairments to use a computer.
