spoken back in 1.8s

Speak, and be understood — instantly

No waiting for a transcript. As you talk, your words cross the language barrier in real time.

Talk naturally — just speak the way you normally would — it keeps up, sentence by sentence
See the words as you speak — your words appear live while you’re still talking
Heard in another language — your listener hears your meaning almost as fast as you say it
Under two seconds — the gap between finishing a sentence and being heard is barely a breath
Keeps up with fast talkers — several sentences in a row are handled together and delivered quickly

in your own voice

spoken back in 1.8s

It still sounds like you

Not a robotic voice — your translated words come out in a voice that sounds like yours.

Your voice, another language — the translation is spoken back in your own voice, tone and accent
Nothing to set up — it picks up your voice from what you’re already saying — no recordings to submit
Your voice is never kept — it’s used just for that moment and then discarded
Clear even in noise — it still works with background noise or if you speak softly
Two-way conversations — both people speak their own language and understand each other
