AI translation for church: how to introduce it to your congregation
AI translation for church services turns the sermon into captions and a spoken voice in other languages as it is preached, so guests and family members can follow it in the same service. This guide is for the pastor or church admin deciding whether to use it, and how to introduce it so the first Sunday goes well.
What AI translation is, and what it is not
AI translation for church works in three steps, all done by computers. Speech recognition writes down what the preacher says. A translation model turns those words into another language, a phrase at a time. The result shows as captions on a screen or a phone, and a computer voice can read it aloud for people listening with earphones.
What it is not:
- Not a person. It does not know your church, your people or what the pastor meant to say. It translates the words it hears.
- Not at the same moment. Captions follow the speaker, because a phrase has to be heard before it can be translated.
- Not a replacement for people. A caption cannot greet a guest, pray with them or invite them to lunch.
Where it helps
Churches have cared that people hear the gospel in their own language since Pentecost (Acts 2). The need is close to home: in 2017 to 2021, more than 1 in 5 people age 5 and older in the United States spoke a language other than English at home, and 62% of them also spoke English very well, so 38% of them spoke English less than very well source.
- Guests. A visitor who speaks another language can follow the whole service on their own phone, from their seat.
- Families. Grandparents who are more at home in another language can sit with children and grandchildren who prefer English, in one service instead of two.
- Overflow and side rooms. A screen in an overflow room, the foyer or a room for parents with babies can show the same captions, and anyone there can follow on a phone.
- The livestream. Captions can sit over the video in your streaming software, and viewers at home can follow on their phones too.
- Several languages at once. One sermon can be captioned in several languages at once, where interpreting would take a person for each. Each caption language uses its own hours.
Livefy is one way to do it. A laptop at the sound desk takes the sermon's sound in a web browser, and the translation appears on the room's screens, in OBS, vMix or ProPresenter, and on guests' own phones, in any of 109 languages. Guests scan a QR code, with no app and no account, and phones can play a translated voice for people with earphones. The demo church shows what a guest sees, and the language checker shows what it does for your languages.
Its limits, said plainly
Like any live translation, it makes mistakes, most often with names, uncommon words and unclear sound. Expect these in particular:
- Names. People's names, place names and names from the Bible can come out wrong, or spelled the way they sound. It helps when the pastor says a reference plainly, book, chapter and verse, before reading it.
- Songs. Songs are sung over music, and their words are usually on the slides already. Pause the translation for the songs, and resume it when the speaking starts again.
- Unclear sound. A mumbled aside, two people talking at once, or a speaker far from the microphone gives it little to work with. What it cannot hear, it cannot translate.
- Humor and wordplay. A joke that rests on an English pun may not carry into another language.
A person can still interpret, and is the better choice where every word matters to someone in the room: prayer with a family, a pastoral conversation, a members' vote, or vows at a wedding or a baptism. A church can use both.
Prepare the sound first
Clear sound matters more than anything else you set up: the translation only has what the computer hears. Take the sermon from a spare output on the mixing board, with only the speaking microphones on it, rather than from a microphone listening to the room. How to translate a sermon live walks through the sound step by step, and the setup guide shows each way to connect, with the cables.
How to tell the congregation
- Start with your leaders. Show the elders, staff or council the demo on their own phones, and agree on why you are doing it before anyone else hears about it.
- Talk to anyone who interprets today, in private, before you announce anything. The next section has ideas for their role.
- Say why, and what it is. Put it in terms of welcome. Say plainly that a computer does the translating, that it will make mistakes, and that the captions help people follow, not replace what the pastor says.
- Show how. Put the QR code on the screen as people arrive, in the bulletin and on a card at the door, and ask the greeters to point guests to it.
- Announce it two or three Sundays running, then let the code on the screen do the work.
A short announcement from the front is enough. For example:
From today, you can follow the sermon in Spanish on your own phone. We use a computer to translate it, so a few words will come out wrong, and we would rather have that than leave anyone out. The code is on the screen, and our greeters can help you with it.
Answering the concerns people raise
"Is it recording us?" Ask any service you consider three things: whether it records the sound, whether it keeps the words, and whether guests must sign up. Then tell the congregation the answers plainly. Livefy, for one, does not record or keep the sound of a service, keeps the words only if the church turns transcripts on, and asks guests for nothing that names them; the privacy page sets out the rest. If part of the service is something you would rather not send to any computer service, such as private prayer requests, pause the translation for that part.
"Will it get things wrong?" Yes, sometimes, and saying so up front keeps trust. The fair way to judge it is a whole service with your own pastor, read by the people it is for: ask two or three guests afterwards what they could follow.
"What happens to our interpreters?" Their gift is still needed, and the role can change rather than end:
- Keep interpreting where a person is the better choice: prayer ministry, pastoral care, members' meetings, weddings and funerals.
- Greet guests in their language and help them get the captions on their phone.
- Read Scripture or pray aloud in that language during the service, or lead a small group in it.
- Keep interpreting one language while captions cover others. If the church has receivers and headsets, the audio feed can send the translated voice into the same transmitter when nobody can interpret.
"Will it change our service?" It should not. The pastor preaches as usual, and the captions can sit low on the screen, out of the way.
A first-Sunday checklist
The week before
- Check your languages with the language checker.
- Run it once with the real microphone and the real sound desk, at a rehearsal or a midweek meeting, and read it on a phone yourself.
- Print the QR code for the bulletin and for a card at the door, and put it on a slide.
- Tell the greeters what it is and how to help a guest scan the code.
- Agree who sits at the computer, and who pauses it for the songs.
Sunday morning
Follow the morning checklist in how to translate a sermon live: the sound, the languages and the code on the screen, then the announcement before the sermon.
During and after
- Pause for the songs, and resume when the speaking starts.
- Afterwards, ask a few guests what they could follow, and which names or words came out wrong.

Questions
Is AI translation accurate enough for a sermon?
Like any live translation, it makes mistakes, most often with names, uncommon words and unclear sound. It is there to help guests follow the sermon, not to be a word-for-word record. Judge it on a whole service with your own pastor.
Will AI translation replace our interpreter?
It does not have to. A person is still the better choice for prayer ministry, pastoral care and meetings where every word matters, and an interpreter can keep one language on Sunday while captions cover others. Talk with your interpreters before you announce anything.
Do guests need an app or an account?
Not when the captions open in the phone's web browser from a QR code. Guests scan it with the camera and read along, or listen with earphones, on their own connection, with no church Wi-Fi needed.
What do we need to start?
Usually a laptop or desktop computer with a web browser at the sound desk (phones and tablets cannot run a service), the sermon's sound from the mixing board, often through a small USB audio interface, an internet connection for that computer, and a screen. Guests bring their own phones.
Is the service recorded?
Livefy does not record or keep the sound of a service, and keeps the words only if the church turns transcripts on. Guests give nothing that names them. The privacy page says what is kept and for how long.
