Speed Reading Training
Tachistoscope Training
Flash words and phrases for milliseconds to build instant recognition. This classic speed reading technique eliminates subvocalization by training your brain to process text faster than you can speak.
Tachistoscope Training
Words or phrases will flash extremely briefly. Type what you saw to train instant recognition without subvocalization.
About Tachistoscope Training
Originally developed for WWII pilot training, tachistoscopes flash content for milliseconds to build instant recognition. This technique bypasses subvocalization and trains your brain to process text at a glance.
The Science Behind Tachistoscope Training
WWII Origins
Tachistoscopes were developed during World War II to train military pilots to instantly identify enemy aircraft. The same principle applies to reading - recognize entire words at a glance instead of letter-by-letter.
Break the Sound Barrier
Most readers subvocalize - they "hear" words in their head at speaking speed (150-250 WPM). By flashing words faster than you can speak them, tachistoscope training forces visual-only processing at 500+ WPM.

- What is a tachistoscope?
- A tachistoscope displays images or words for a precisely controlled, very brief interval. Originally a mechanical device used in perception research, it is now normally software — as it is here.
- What is a tachistoscope used for?
- It was built to study how much the eye takes in during a single fixation. In reading training it is used to push recognition speed, by showing words too briefly to decode letter by letter.
- How fast can the human eye recognise a word?
- Skilled readers identify familiar words in well under 250 milliseconds, and often nearer 100. Recognition is far quicker for common words than for unfamiliar ones.
- Does tachistoscope training improve reading?
- It reliably increases how fast you recognise briefly presented words. Whether that carries over to continuous reading is less certain, since normal reading also involves eye movement planning and comprehension that this exercise does not train.
- Is this tachistoscope free?
- Yes, it runs in the browser with no signup.
