Live event, Berlin, 18 October 2026. Four languages, two hours of talks, a full room. These are the medians from that session.
The speech recogniser stamps every word with the moment it was spoken. We take the last word of each sentence and the moment the translated caption left for the listeners' phones, and for voice the moment the first sound was queued plus whatever audio was already waiting ahead of it. Medians over 1,750 sentences. Most tools in this category publish no number at all; the few that do give a best case.
No booth, no hired interpreters, no crates of headsets to hand out and collect.
One cable from the mixer, or an NDI feed. Whatever the crew already runs.
Attendees scan it. Browser only. No app, no sign-up, free for them.
A natural voice in their earbuds, captions underneath. A person watches every language live.
A top interpreter still wins on nuance. Babel covers every language in the room, all day, at a price most events can pay. And someone is watching it the whole time.
Give it the agenda, the deck and the speaker names. It knows your acronyms and product words before the first talk.
Lock how a brand name or a term is translated. It holds for the whole event, in every language.
An operator sees every language live, pauses a lane, fixes a term in seconds. Not a black box.
Two-way Q&A: a question asked in French reaches the stage in English and the rest of the room in theirs.
Send your client a preview link before doors open. They hear every name pronounced and approve the terminology, in every language.
Clients ask for translation. Booths are scarce and eat the margin. Babel is a feed in, captions and audio out, priced per day, with your name on it.
Pick the size of your event. Live voice, captions and NDI come with every plan. No annual package, no hours that expire.
Two days save 15%, three or more save 25%. Fifteen minutes free to try on your own audio.
If Babel doesn't run on the day, you don't pay.

Usually $5,750–$8,050 for the same event. An estimate, not a quote.
Audio is processed live to make the translation and is not stored by default. Transcripts stay for your event summary and go when you say so. We never use your events to train anything. Attendees give us no personal data; they scan and listen.
Running something sensitive? A zero-retention mode keeps nothing at all. The details.
Captions show about one and a half seconds after the speaker finishes a sentence. The translated voice starts about five seconds after the speaker begins one. Those are medians we measured at a live event in October 2026, not a promise of the best case.
Good audio matters most: a stage microphone, not a laptop mic. Before the event you give Babel the agenda, speaker names and your terms, and you can lock how a word is translated. A person watches every language live and can fix a term in seconds. A strong accent still costs some accuracy, as it would for anyone listening.
Great interpreters win on nuance. They also cost $1,500–2,000 per language per day, plus a booth and headsets, and you need one team per language. Babel covers every language in the room all day for one price, and most events that use it could not have afforded interpreters at all.
A phone and any earbuds. They scan a code and listen in the browser. No app, no account, nothing to download. iPhones keep playing with the screen on; a background mode for locked phones is in testing.
