Open Dictation is a listening and dictation trainer for seven languages: Romanian, French, Spanish, Italian, Portuguese, German, and English. HOW IT WORKS A native speaker sentence plays. No text is shown. You listen, then type what you heard. A character-level diff shows exactly where you went wrong — not just that you made an error, but which characters. The spaced repetition algorithm schedules each sentence to return at the moment your brain is about to forget it. Over thousands of repetitions, your ear sharpens. Sounds you once missed become automatic. This is how children acquire language, compressed into deliberate daily practice. WHAT'S INCLUDED · Thousands of sentences per language — real speakers, natural speech · Instant translations in 13 languages for every sentence · Spaced repetition scheduling based on your personal error history · Sign in with Apple or Google to sync your progress across devices · The web app at sitedictation.com/play runs the same experience in your browser · No account required to start — progress stays on your device FREE TIER + PRO Free tier includes 1,000 unique sentences per language. Pro subscription removes the cap and unlocks the full corpus: 26,000+ Romanian, 70,000+ French, 159,000+ Portuguese, and more. HONEST ABOUT WHAT IT IS This is not a gamified app. There are no points, no streaks to protect, no social features. It is a training tool, built by someone who used it daily to reach C1 Romanian.
