Frequently Asked Questions

What is the Natural Decoding Method?

The Natural Decoding Method is a brain-friendly approach to language learning rooted in decades of brain-friendly language research. Instead of rote vocabulary memorization, you learn through decoding (word-for-word translation) and active listening. Your brain naturally recognizes patterns, just like a child learning their mother tongue.

Do I need an internet connection?

AI processing requires an API key (Google Gemini, OpenAI, Claude, or OpenRouter, your key, your provider, direct connection). Music playback and previously downloaded content work offline. On-device AI (Gemma) is in development.

What languages can I learn?

Over 20 languages: Spanish, French, Italian, Portuguese, Turkish, Japanese, Korean, Chinese (Mandarin), Arabic, Hindi, Russian, German, Dutch, Swedish, Polish, Greek, Czech, Thai, Vietnamese, and Indonesian.

How much does DopaSpeak cost?

DopaSpeak costs €7.99 per month or €11.99 per year (save 50%). No hidden fees, no ads, no in-app purchases.

What devices are supported?

Currently Android devices with at least 6 GB of RAM. For optimal performance, we recommend 8+ GB RAM. An iOS version is planned.

How does learning through music work?

You paste a song link or enter the artist and title. DopaSpeak fetches the lyrics automatically, splits them into verses, and decodes each line word by word. You learn the language through music you love, emotionally anchored and deeply motivating.

Why we built this

From the founder

"It started with a Spanish song. I was in the car, hearing a track I didn't understand. But I wanted to. Not tomorrow, not after 200 days of Duolingo streak. Now. I tried to Google the lyrics, translate, learn. It didn't work. School English never worked for me, vocabulary apps even less. I just wanted to understand what that one artist was singing in his favorite song.

DopaSpeak is the app I would have needed back then. You pick the music you love, and the AI on your phone breaks it down for you, word by word. No cloud, no data leaks, no ads. Just you, your song, and your brain.

We're building DopaSpeak in Germany, GDPR-compliant, because I want my daughter Ruby Mae to one day learn languages with her favorite music, without her data being sold."
