LingoDuet translates face-to-face conversations in real time — entirely on your iPhone. Place the phone between two speakers, press to talk, and hear the translation instantly.
Built for people who need to communicate across languages — without handing their voice to a cloud server.
Your voice never leaves your iPhone. Speech recognition, translation, and text-to-speech all run locally using Apple's Neural Engine.
After a one-time model download, LingoDuet works on a plane, in a remote village, or anywhere without a signal.
Place the phone on a table. The screen splits in two — each person reads their translation in their own orientation.
Works with AirPods, Bluetooth earbuds, or just the built-in speaker. No proprietary hardware required.
Under 3 seconds from end of speech to translated audio playback — fast enough for a natural conversation flow.
English, Turkish, Spanish, German, French, Chinese, Japanese, Arabic, Hindi, Portuguese, Russian, Korean, Italian, Polish, Dutch.
A clean, focused interface built for real conversations.
Choose your language and your conversation partner's language from 15 supported options. You can change the pair at any time during a conversation.
The screen divides into two panels — one for you (bottom) and one for your conversation partner (top, rotated 180°). Each person sees their translations in the right orientation.
Hold the Push-to-Talk button on your side while speaking. Release when done. LingoDuet transcribes your speech, translates it, and reads it aloud in the other person's language — within seconds.
Audio plays through the speaker or your Bluetooth headphones. Use the Volume Boost option for noisy environments. Optionally route translations privately to earbuds so only you hear the other person's translation.
All 15 languages work in any combination — translate between any pair.
