Interpreters cost a lot and are hard to book
Simultaneous interpreters usually work in pairs for each language and get booked weeks ahead. Hardly anyone does that for an evening event. So everything stays in one language.

HostWelcome, great to have everyone here.
Willkommen, schön, dass alle da sind.
Sound familiar?
Half the room nods along.
The other half guesses.
Reading subtitles isn't listening
People who read along are looking at their phones, not at you. Their questions come too late, or never.
The quiet ones stay quiet
If you can't follow everything, you don't speak up. Good ideas get lost, and nobody even notices.
Every meeting where someone only gets half of it costs you a little trust. Next time, that person shows up less often, asks fewer questions and stays on the sidelines.
What happens behind the scenes
From mouth to ear.
Four stations.
The moment you finish a sentence, it runs across our desk. All models work on our own graphics card, nothing goes to a cloud AI.
Two modes, one piece of software
On a video call or in the same room.

Example: interpreters for 2 hours, 2 extra languages, €93 per hour each€372
€93 is the statutory hourly rate German courts pay interpreters (Section 9(5) JVEG, as of 2026). Freelance rates are often higher, and simultaneous interpreters usually work in pairs. Just an example calculation, not a quote.

Three languages. Every direction.
Every supported language works for speaking and for listening. Hover over the table: wherever speaker and listener share a language, there's no AI involved.

Good to know
- One host speaks, everyone else listens in their own language. Made for talks, sermons, trainings and moderation.
- Translations are spoken by an AI voice. Anyone who shares your language hears your real voice.
- Lumeya Translate waits for the end of a sentence so the meaning is right, then translates the whole sentence.
- Guests need no account and no app, just the link.
Picture this
Your next evening event, in three languages.
You stand at the front and talk the way you always do, in English. In the second row, someone hears you in Arabic. Next to them, someone hears you in German. Nobody is staring at a phone to read along. Everyone laughs at the same moment. And when it's over, people stick around, because they caught every word.
Lumeya Translate comes from the same workshop as Lumeya Call and Lumeya Web. Our rule: conversations don't belong in someone else's AI cloud. That's why the translation runs on our own graphics card, and why this page only shows numbers we measured ourselves.

What does Lumeya Translate cost?
The preview on speak.lumeya.ai is free. For comparison, German courts pay interpreters €93 per hour (Section 9(5) JVEG). No subscription, no credit card.
Do my guests need an app?
No. For an online meeting, a current browser with a microphone or speakers is all it takes. Guests don't need an account, just the link.
How fast does the translation come through?
In our measurements, translation started within 1.4 seconds of the end of the sentence for 95% of sentences. Network and speakers add to that. Lumeya Translate waits until a sentence is finished so the meaning comes out right.
What about Romanian, Russian and other languages?
Romanian and Russian are next. We only add a language once its voice and speech recognition clear our bar.
Who's behind it?
Lumeya Translate is made by Luminant Mind e.U. in Vienna, the team behind Lumeya Call and Lumeya Web.
At your next meeting,
everyone gets you.
