Speak freely across languages — anywhere, with anyone.
DuoVox translates conversations in real time. Whether you're travelling abroad or working with international clients, you'll understand every word instantly.
See both sides of the dialogue separately, so nothing gets mixed up. Each language gets its own dedicated panel with real-time text.
From English and Russian to Japanese, Arabic, Hindi and many more. The full interface is available in every supported language, not just the transcription.
Get fast, natural-sounding translations that follow the flow of real speech. DuoVox is designed to handle idioms, accents, and everyday language.
No signal? No problem. DuoVox includes built-in offline transcription that works without internet — available on all tiers. Perfect for holidays and travel.
On your phone for travel and face-to-face conversations, or on your computer for meetings, calls and media. Same experience, any device.
Audio is processed in real time and never stored. Transcriptions exist only on your device and are cleared when your session ends. Free tier works entirely on-device; paid tiers stream audio to our AI provider for processing only — it is not retained. Enable Private Mode for zero data retention.
Select a primary language and a target language. DuoVox supports 51 languages on paid tiers and 28 offline.
Hit the start button and speak naturally. DuoVox listens through your microphone and begins transcribing instantly.
Each language gets its own panel. You see your words on the left and the translation on the right — in real time.
DuoVox automatically detects who's speaking and routes text to the correct lane. Just talk naturally — it keeps up.

DuoVox uses AI-powered speech recognition and machine translation to assist communication. Like all transcription and translation tools, results may contain errors and should not be treated as a verbatim or certified record. Accuracy can be affected by background noise, accents, microphone quality, overlapping speech and domain-specific terminology. DuoVox is a communication aid and should not be relied upon for legal, medical, safety-critical, financial or official purposes. Always verify important information independently.
