Screen readers

Screen readers are applications that read text on a screen out loud, thus making navigation and operation easier.

• "Narrator" is a screen reader integrated into Windows that offers speech output for easy navigation.
• "VoiceOver" is an application integrated into macOS and iOS that reads content out loud and can be operated by voice commands.
• "TalkBack" is an accessibility feature in Android for smartphones and tablets that reads texts, buttons, menus, and other content on the screen out loud; it also describes symbols, messages, and operation controls.

With "VoiceOver" and "TalkBack", users can not only listen to content, but also use voice commands to control many device functions.

PDF text recognition and read-aloud functions

Software like Adobe Acrobat Reader and Foxit Reader are equipped with functions to magnify and read PDF documents out loud. Many web browsers can also directly open PDFs, read them out loud, and often make adjustments to them such as magnifying them or changing their colors.

Web browser extensions

In addition to the integrated functions, internet browsers offer numerous extensions that improve accessibility. Many of these are free and ideal for the visually impaired.

• "High Contrast" is an extension for Chrome that improves contrast and adjusts the colors.
• "Keyboard Navigation" allows navigation of websites using the keyboard, for example with the arrow keys.
• "Reader Mode" removes distracting content such as advertisements and displays only the text of a web page; available as a function or extension in many browsers.
