Speak any language.
Hear it back in your own.
Duo Voice transcribes your speech and translates it in real time — directly in the browser. No installs, no setup, no waiting for a sentence to finish. Just open the page and talk.
Three things, done in real time.
Built for moments when you need to understand the other person quickly — or make yourself understood — without juggling apps or waiting for a translation to load.
Voice → Text
The system transcribes your speech as you talk, with virtually no delay. Useful for dictation, notes, captions, and capturing thoughts on the fly. Stays accurate even with background noise — and you can copy, edit, or save instantly.
Text → Translation
Translation appears side-by-side with the source. Speak in one language, read in another — updates flow continuously, so the conversation stays natural and never has to pause.
Flip mode
Built for live conversations. Swap the direction with one click — speak Russian and read English, then flip and reply the other way. Ideal for interviews, consults, and online meetings where two people need to understand each other.
Mic + system audio, in parallel — no interference.
Duo Voice can listen to your microphone and your system audio at the same time, transcribing both. So a video call becomes a two-way bilingual conversation — you talk, they talk, and both sides get understood in real time.
Independent processing
Each channel is processed on its own pipeline, so the streams don't bleed into each other. Recognition stays clean even when you and the other person speak at the same time.
Speaker-aware transcripts
Every line in the transcript is tagged MIC or SYS — so a saved conversation reads like a script, not a transcript blob.
Built for video calls and lectures
Useful in webinars, interviews, and online classes — listen to the speaker, talk back, and get a clean record of both sides. No virtual cables, no extra software.
Five steps. About ten seconds.
