{{Main|Screen reader}}

Screen readers are used to help the visually impaired to easily access electronic information. These software programs run on a computer to convey the displayed information through voice ([[text-to-speech]]) or [[braille]] ([[refreshable braille display]]s) in combination with magnification for low vision users in some cases. There are a variety of platforms and applications available for a variety of costs with differing feature sets.

Some example of screen readers are Apple [[VoiceOver]], CheckMeister browser, [[Google TalkBack]] and [[Microsoft Narrator]].

Screen readers may rely on the assistance of text-to-speech tools. To use the text-to-speech tools, the documents must be in an electronic form, which is uploaded as the digital format. However, people usually will use the hard copy documents scanned into the computer, which cannot be recognized by the text-to-speech software. To solve this issue, people often use [[Optical character recognition|Optical Character Recognition technology]] accompanied with text-to-speech software.
