Live spoken sermon translation for church services

Tuned for biblical and liturgical language.
Guests hear translation as the preacher speaks.
English, Chinese, French, German, Korean, Portuguese, Russian, Spanish, and Ukrainian.

Sermon Relay was started for a bilingual congregation at a Pentecostal church in Irving, Texas. Families and friends worship together, not always sharing the same language. We want every guest and member to feel welcome and enjoy the service.

Sermon Relay is a work in progress. Translation may make mistakes. This website may have mistakes. Features may change or disappear. We’re grateful for feedback that helps us improve.

“I understood everything in today’s service, even if there were a few mistakes.”

“It’s better than using a translator app on the phone and even a live interpreter. Translator apps on phones lag, stall, and make even worse mistakes. Interpreters slip up too and often skip whole parts. This app translates everything and keeps up with speech.”

Get started

How it works

Sermon Relay runs on a laptop during the service. The preacher’s voice comes from the church sound system into the app. Guests hear the translation on wireless earpieces, or on their phones by scanning a QR code.

What you need

A computer with Wi‑Fi and a normal web browser. We use a MacBook Pro.
A feed of the spoken sermon from your church sound board.
An in/out USB audio adapter to connect the sound board to the laptop.
For phone listening: guest phones on church Wi‑Fi (or cellular) and a QR code or join link from the booth.

What we use (RF path)

USB audio adapter (sound board to laptop)
Castline Mogami W2582 cable for line-level out to the transmitter AUX jack.
EXMAX ATG‑100T Plus transmitter (base unit near the laptop)
EXMAX ATG‑100T Plus receiver for each listener
EXMAX SE35 earpieces

From the pulpit to the guest

Church mics pick up the preacher
Sound board sends that voice to the laptop
Sermon Relay translates in the browser
Guests hear it on wireless earpieces or their phones

Tips for the operator

Turn off notifications on the laptop (Do Not Disturb / Focus, messages, calendar alerts). Pop-ups and chimes can interrupt the service.
Use that laptop only for translation during the service, not for slides, streaming, or other jobs at the same time.
Ask for a clean speech feed from the sound person. The app may have difficulty understanding speech with background music, more so with singing.
Have the sound person set sensible level on the board. If it’s too loud, there may be distortion and the app may have difficulty understanding speech.
Set volume on the laptop and the receivers. Guests can turn their own earpiece up or down. The app has no separate volume control for the outgoing sound.
Before the service: plug in the audio adapter · allow the microphone in the browser · choose the USB audio device · watch the meter · try a short test.

Payments via secure checkout; we never store full card numbers.

Sermon Relay is a work in progress. Translation may make mistakes. This website may have mistakes. Features may change or disappear.

Translation hours are counted per output language. One hour into Spanish and one hour into Russian is two hours. Hours (translation and phone-listener) round up to the nearest minute.

Captions on phone lets guests read the translation on their phones. On the $59 / $590 plan it is an add-on at $29 / month or $290 / year. Pay as you go includes it. Captions do not change phone-listener hours.
