A screen reader is a form of assistive technology (AT) which is essential to people who are blind, as well as useful to people who are visually impaired,illiterate, or have a learning disability Screen readers are software applications that attempt to convey what people with normal eyesight see on a display to their users via non-visual means, like text-to-speech,, sound icons, or a Braille device. They do this by applying a wide variety of techniques that include for example interacting with dedicated accessibility APIs, using various operating system features (like inter-process communication and querying user interface properties) and employing hooking techniques.

Microsoft Windows operating systems have included the Microsoft Narrator screen reader since Windows 2000. Apple Inc.'s macOS, iOS, and tvOS include VoiceOver as a built-in screen reader, while Google's Android provides Talkback screen reader since 2009. Similarly, Android-based devices from Amazon provide the VoiceView screen reader. BlackBerry 10 devices such as the BlackBerry Z30 also include a built-in screen reader. There is also a free screen reader application for older BlackBerry (BBOS7 and earlier) devices

There are also popular free and open source screen readers, such as Speakup and Orca for Linux and Unix-like systems and NonVisual Desktop Access for Windows.

The most widely used screen readers are often separate commercial products: JAWS from Freedom Scientific, Window-Eyes from GW Micro, Dolphin Supernova by Dolphin, System Access from Serotek, and ZoomText Magnifier/Reader from AiSquared are prominent examples.
