Scientific Language Learning with Letspeaky

Discover why oral-first flashcards combined with spaced repetition are recommended by world-class polyglots and cognitive scientists.

Why Spaced Repetition Works

Spaced repetition (SRS) is a scientifically validated learning technique that optimizes the intervals between reviews. Instead of cramming vocabulary, SRS introduces words just before they slip from your active memory, maximizing cognitive retention.

  • Increases memory retention by 150%
  • Prevents the natural 'forgetting curve'
  • Saves hours of study time weekly

The Power of Oral Practice

Traditional flashcards only train passive recognition. Letspeaky combines visual vocabulary cards with instant text-to-speech audio feedback. By listening and mimicking the native accent instantly, you build crucial motor-reflex connections in your brain.

  • Builds automatic speaking confidence
  • Trains listening comprehension
  • Improves speech-production reflexes
