Lumen Speak

Finally speak the language you've been learning. Lumen's voice tutor gives you real conversation practice, judgment-free. Try it free for 3 days.

Lumen is your personal AI-powered speaking coach — a tutor who actually listens, talks back, and helps you build real conversational fluency in a new language.

Most apps teach vocabulary through flashcards and quizzes. Lumen works differently: you have real, live spoken conversations with an AI tutor that adapts to exactly where you are — correcting you gently in the moment, adjusting its pace and vocabulary to your level, and remembering what you talked about last time so every session builds on the one before.

How it works • A short spoken placement chat places you at your real level — no guessing • Get a personalized learning path built just for you • Practice real conversations by voice with a tutor that listens and responds naturally • Get corrected in the moment, not after the fact • Save new vocabulary and review it with smart spaced repetition • Track your streak, progress, and level as you grow

Why it's different • Live voice conversation, not scripted dialogue trees • A tutor that remembers your last class and builds on it • Native-language support for beginners, full immersion as you progress • Personalized correction style, pacing, and topics — tuned to you

Practice Spanish, French, German, Italian, Portuguese, Japanese, and more — anytime, anywhere, at your own pace.
