NVDA (NonVisual Desktop Access) is a free “screen reader” which enables blind and vision impaired people to use computers. It reads the text on the screen in a computerised voice. You can control what is read to you by moving the cursor to the relevant area of text with a mouse or the arrows on your keyboard.
NVDA can also convert the text into braille if the computer user owns a device called a “braille display”.
NVDA provides the key to education and employment for many blind people. It also provides access to social networking, online shopping, banking and news.
