Talk across languages on a video call
Rosetta adds live, translated subtitles to a video call. Start a call, share the room code, and each person picks their own language. What you say is transcribed and shown to the other person as subtitles in their language — and read aloud if they want. Perfect for family abroad, remote work, and meeting people across a language barrier.
Calls are peer-to-peer (device to device), so your conversation is not stored on a server. It works right in the browser with no app to install — Conversation mode covers face-to-face chats on one phone, and text & voice translation handles quick lookups.
How to start a translated video call
- Open the video call — this page opens Rosetta on the Video Call tab.
- Pick your languages — choose the language you speak and the language you want captions in.
- Start a call & share the code — tap Start a call and send the room code to the other person.
- See live subtitles — once they join, each of you sees the other’s speech as translated subtitles.
Translating a call on WhatsApp, Zoom, Google Meet or Skype
A common question: can you add live translation inside WhatsApp, Zoom, Google Meet or Skype? Honestly — no tool can inject subtitles into another app's call, and any site claiming otherwise is overselling. What works in practice:
- Use Rosetta as the call itself. It runs in the browser, so there is no app for either person to install — you send a room code and both of you see translated subtitles live. This is the simplest option when you are setting up the call.
- Already on WhatsApp or Zoom? Put that call on speakerphone and open conversation mode on a second device next to it. It listens, translates and reads the reply aloud, so the other side hears it through your call.
- Meeting in person instead? Conversation mode on one phone handles a face-to-face chat — you each tap your own language and talk normally.
Zoom and Google Meet do offer their own live captions, but those transcribe into the same language rather than translating between two. Rosetta is aimed at the case where the two of you do not share a language at all.
Does it work on a phone?
Yes. Translated video calls work in Chrome on Android and in Safari on iPhone, with camera and microphone permission allowed when the browser asks. A few things worth knowing before an important call:
- Keep the browser tab in the foreground — phones pause the microphone for background tabs.
- Headphones or earbuds noticeably improve accuracy, because the speaker's audio does not feed back into the mic.
- Speak in short, complete sentences and pause briefly. Speech recognition works far better on "Can you send the address?" than on a long unbroken paragraph.
- Wi-Fi is preferable to mobile data for video, since the call is peer-to-peer.
Frequently asked questions
Is the video call translator free?
Yes — completely free, with no sign-up. Just start a call and share the room code.
Can I translate a WhatsApp or Zoom video call?
Not from inside those apps — no tool can add subtitles to another app's call. Either make the call in Rosetta instead, or put your WhatsApp or Zoom call on speakerphone and run conversation mode on a second device beside it.
Does it work on Android and iPhone?
Yes. Use Chrome on Android or Safari on iPhone, allow camera and microphone access, and keep the tab in the foreground so the phone does not pause the mic.
Does the other person need to install anything?
No. They open the link in their browser, pick the language they speak, and join with the room code — nothing to download on either side.
Is there a time limit on the call?
No. Calls are peer-to-peer between the two devices, so there is no per-minute cost and no meeting timer.
How does it translate the call?
Your speech is transcribed, translated into the other person’s language, and shown to them as live subtitles (and read aloud if enabled).
Is the call private?
Yes. Calls are peer-to-peer between the two devices and are not stored on any server.
Which browser works best?
Chrome or Edge on a laptop or Android phone work best, with camera and microphone access allowed.
How many languages are supported?
Over 40 world and regional languages, including Hindi, Gujarati, Marathi, Tamil, Spanish, French, Arabic, Chinese, Japanese and more.
