Screen Reading Software
Screen readers (or speech output systems) are software programmes designed to give blind people access to standard computers and software, such as word processors, spreadsheets, email and Internet browsers. A standard computer, whether laptop or desktop, can be adapted by adding screen reading technology, which enables the computer to talk to the user.
The screen reader allows navigation around the computer screen and presents what is happening on the screen to the user in a meaningful way using speech output. The user then inputs to the computer using a combination of standard keyboard and keyboard shortcuts instead of a mouse. Examples of screen reading software include JAWS, Supernova, and Kurzweil
JAWS
JAWS is a software programme which speaks out whatever is on the screen. This enables a blind user to listen to, rather than look at the screen content. JAWS speaks using a voice synthesiser, and the user can adjust the speed of screen reading, as well as the voice used, to suit their personal preferences.
Supernova
Supernova is another option for screen reading. It is used mainly when the person has some residual sight as it comes with a magnifying option.
Kurzweil is a screenreader which is available in two versions: one designed for blind users (Kurzweil 1000) and another designed for users with literacy difficulties (Kurzweil 3000). Kurzweil 1000 makes printed or electronic text available to a blind user, by using text to speech software in naturally sounding voices. Kurzweil 3000 also has some magnification features and it allows the user to scan in hard copy documents and have them read aloud, and if necessary, magnified. Kurzweil 3000 also has a number of additional 'study' features including notebooks, thesaurus and text highlighting and as a package, can help improve reading speed and comprehension. When purchasing, Kurzweil it is important to check that the scanner is compatible with the software for optimum use. Visit www.kurzweiledu.com for an online demonstration of Kurzweil 3000.
In Windows computers, you can also activate the Narrator option in the Accessibility (XP) or Customisation (Vista or Windows 7) options in the Control Panel. On Apple Mac computers, VoiceOver from the Accessibility Centre works in a similar manner.
Free downloadable screen readers include Non-Visual Desktop Access (NDVA) and Thunder.
