Bible names and church terms in live sermon translation

Why names and terms are the hardest part

AI translation works in two steps that happen almost at once: it recognises the spoken words, then translates them. Both steps lean on what is common in everyday language. Ordinary sentences are heard and translated well because the system has seen countless similar ones. Rare names and specialist words are a different story.

• Names sound like other words. "Job" the man and "job" the work. "Mark" the gospel and "mark" the stain. Without context, the system has to guess.
• Names differ between languages. Elijah is Elia in German, Élie in French, Eliasz in Polish and Ilia in Ukrainian. A good translation uses the form that a reader of that language knows from their own Bible.
• Theological terms carry history. Words like justification, atonement, sanctification, covenant or grace have established translations in each church tradition. A literal translation can be understandable yet sound wrong to a believer.
• Church traditions use different words. Communion, the Eucharist, the Lord's Supper and Mass refer to related things but are not interchangeable, and the same is true in every language.
• Quotations are compressed. When a preacher quotes half a verse from memory, the AI translates what it hears, not the wording of the Bible translation the listener uses at home.

What ChurchTranslate does

ChurchTranslate is built for church services, so the translation is given context: it keeps Bible names and church terms in mind while translating. In addition, a terminology list per language is used to correct known terms in the captions, so that common names and church words appear in the form readers of that language expect.

We want to be modest about this. It helps noticeably with frequent names and well-known terms. It does not make the system infallible. Rare names, unusual pronunciations and very dense theological passages can still come out wrong, and the translated voice may sometimes pronounce a name differently from how the listener knows it.

Tips for preachers

You do not need to change how you preach. A few habits make a real difference, and most of them also help native listeners.

1. 01
   Announce references in full

   Say "the Gospel of John, chapter three, verse sixteen" rather than "John three sixteen" at speed. The extra words give the AI context.

2. 02
   Introduce unusual names

   "The prophet Habakkuk" is easier to recognise and translate than "Habakkuk" on its own. A short description anchors the name.

3. 03
   Pause after a quotation

   Reading a verse, then pausing for a breath before explaining it, gives the translation time to catch up and separates the quote from your comment.

4. 04
   Explain jargon once

   If you use a word like propitiation or a Hebrew or Greek term, add a short explanation. Translators, human and AI alike, benefit, and so do many native listeners.

5. 05
   Watch idioms and wordplay

   Puns, rhymes and cultural references ("a bit like a wet Bank Holiday Monday") rarely survive translation. Use them if you like, but do not let a key point depend on them.

6. 06
   Keep a steady pace

   Speaking quickly is less of a problem than speeding up at the end. A rushed final application is where listeners lose the thread.

Tips for the technician

• Clean audio first. Many apparent name errors are actually recognition errors caused by echo or music. The audio setup guide helps.
• Set the speaker language correctly. If the reader of the Old Testament lesson is Romanian, switch the speaker language for that reading.
• Correct the transcript afterwards. If a name came out wrong, fix it in the service transcript so it is right for anyone who rereads it.

Readings in another language

Some churches invite a newcomer to read the Bible lesson in their own language. That is a lovely way to include people, and it also helps the translation: the technician switches the speaker language to the reader's language for the reading, and listeners in other languages keep following. Ask the reader to announce the book and chapter clearly before they start.

Liturgy, creeds and set prayers

Churches with a fixed liturgy have an advantage: many listeners already know the Lord's Prayer, the Apostles' Creed or the Gloria in their own language. Some churches print the main liturgical texts in the visitors' languages, or show them on screen, so people can pray along in the words they know rather than following a live translation. The translation then focuses on the sermon, the intercessions and the notices.

Setting expectations with listeners

Tell visitors honestly that the translation is done by AI and will sometimes get names wrong. Most people are forgiving when they know. What frustrates them is not the occasional mistake but missing the whole sermon. Being open about the limits also helps them use the original text option when something sounds odd.
