How simultaneous translation works in your church
In a church with visitors, missions or a migrant congregation, the sermon is preached in a single language. Una Voz solves this with no human interpreters to hire and no radio equipment to maintain: the preacher speaks and each attendee listens to and reads the message in their own language, on their own phone, by scanning a QR code.
No apps to install, no hardware to buy, ready in minutes.
From the sound desk to the attendee’s phone
This is how simultaneous translation works in church, from start to finish — one single path, no hidden steps.
Set up your church
From your church dashboard you create the service and choose the languages you want to translate into. You do it once and it is ready for every Sunday: no hardware to install and no outside technician to call.
Share the QR code
Your church has its own QR code and link. Print it in the bulletin, project it before the service starts or stick it at the entrance — it is the only thing your congregation needs to see.
The preacher speaks
On the phone or computer at the sound desk, the operator presses Broadcast. From then on the preacher just speaks normally, like any other Sunday.
The AI listens, translates and turns it into voice
The audio is recognized, translated and synthesized again as natural voice in every configured language, within a few seconds — tuned for sermons, with your own glossary and Bible quotations in their official wording.
Each attendee scans and listens
The congregation scans the QR code from their seat, picks their language and follows the message by listening and reading at the same time, without installing any app and without radio headsets to hand out or collect.

No apps, no hardware, ready in minutes
There is nothing to download. The link the QR code opens works directly in the browser of the attendee’s phone; anyone who wants to can add it to their home screen and from then on it behaves like an app, but there is never an app store in between.
There is no need to buy radio receivers or headsets to hand out and collect every Sunday either: the only hardware is the phone the attendee already carries in their pocket.
The audio is designed to keep playing even when they put the phone away with the screen locked, so they do not have to hold it in their hand through a whole 45-minute sermon.
For your church team
Creating the service and sharing the QR code takes minutes, not an afternoon of setup. Everything is managed from a single dashboard, designed for whoever runs the sound desk or the church administration, not for an IT department.
- Languages and voice, your way
- You choose how many languages you offer and with what voice — from subtitles to natural voice — depending on your church’s plan. Adding a new language is a setting in the dashboard, not an integration.
- Glossary and sermon outline
- Upload the outline and add the proper names or terms your church uses often: the translation recognizes them from the very first sentence, instead of learning them as it goes.
- Access code and your own branding
- Your church has its own access code, logo and colors. Attendees join your church’s translation, not a generic app shared with other congregations.
- Usage and live listeners
- From the same dashboard you see how many people are listening and in which language, service by service — no spreadsheets and no manual counting.
