Real-time voice translation · private beta

Two people.
Two languages.
One conversation.

You speak. A beat later, the other person hears it in their language — as text and voice. Then they answer, and you hear them in yours.

How it works

One spoken turn, five steps, a few seconds

Each person joins the same room on their own device and picks their language. When one talks, Setu handles the rest and delivers to the other — the transcript to both.

01 · Speaker
You speak
Mic streams to the bridge over a secure WebSocket.
02 · Detect
End of turn
Voice-activity detection segments your utterance.
03 · Understand
Transcribe
Speech-to-text in your language.
04 · Translate
Into theirs
On-device Indic translation; nothing stored.
05 · Listener
They hear it
Text and a spoken voice, in their language.
Built for

Conversations that don't share a language

Made for noisy rooms

A translation reaches you even while your own mic stays open — no waiting for silence. Built for conference floors, not quiet booths.

Each side, its own settings

Choose the language you speak and the one you want to hear, your voice, and how sensitive turn-detection is. Saved on your device.

Nothing is kept

Audio is transcribed and dropped. Setu keeps no recording, no server-side transcript, and no account — the conversation lives only in your two browsers.

No install

Open a link on any phone or laptop, type a shared room code, and start. Works over ordinary Wi-Fi and cellular.

Languages
English हिन्दी Hindi বাংলা Bengali తెలుగు Telugu मराठी Marathi தமிழ் Tamil · text only

Any pair, either direction. All six translate as text; five also speak aloud (Tamil voice is on the way).

Try it with someone across the table.

Open the demo, share the room code, and have a conversation neither of you could have had a minute ago.
