Text-to-Speech

Reads on-screen content aloud to support comprehension and information processing.

What does this setting do?

Text-to-speech converts written text into spoken language. It is especially helpful for people who struggle with reading long or dense text, have slower visual processing or benefit from auditory learning. All major operating systems include built-in TTS functions with customizable voices and speeds.

Commonly used for the following difficulties:

Difficulty Reading or Processing Long Text

Long text passages can cause fatigue or reduced comprehension. Reader modes, spacing adjustments and distraction-free views support readability.

Slow Information Processing

Users who process information slowly need more time for interactions. Reduced motion, clearer layouts and extended time settings improve usability.

Cognitive Overload

Complex or information-heavy interfaces can be overwhelming. Simplified layouts, reduced distractions and focus modes help manage cognitive load.
