Why these fonts?

Choose the font you find easiest to read. Studies have not found that special "dyslexia fonts" help people read faster or more accurately. More space between letters and words does help some readers, so try the spacing setting too.

Focus mode hides the Map and Help links, the breadcrumb and the footer, so only the page you are reading is left.

Reading voice and speed

Emma is a computer voice, made with the open Kokoro model. Her readings are saved on this site. Where a part has no Emma reading yet, your device's own voice reads it.

Reading speed

The number is how many times faster than normal. 1.5 is one and a half times as fast. The voice keeps its pitch.
