High magnifications or the reading aloud of screen contents make texts or graphics accessible to people with visual impairments.
Texts converted to Braille are readable for the blind. However, this is only possible in combination with a Braille display. In addition to the texts, the screen reader also converts the controls and other screen elements into braille, while speech synthesizers read the contents aloud. A text-to-speech system (TTS) reproduces continuous text by means of acoustic speech output.
