Screen readers can be used to access web content at home, at work or in educational environments.Īs well as providing a speech output, some screen reader technologies allow the magnification of web content and altering the appearance of a web page, for example, by increasing the contrasts or inverting colors.

Some screen reader technologies also allow their users to access web content via a refreshable braille display, which is particularly useful for deaf-blind people. This is typically achieved by the screen reader ‘announcing’ the site’s content (headings, text, links, images and so on) in an artificial voice – also known as a speech synthesizer – via the user’s device’s sound card. The content they can decipher includes emails, web pages and other documents. They are designed to run on the most popular operating systems, like Windows, iOS and Android. Screen readers are a specialist text-to-speech software that can be used by people with little to no vision to access website content, generally on a computer or mobile device.
