How it works
From the sound desk to every pew.
Three things to set up once. After that, Sunday is one button at the desk, and everyone in the room follows in their own language.
Set up once
Three things, then it’s Sunday.
Step 1: Plug in
Connect a laptop or an old phone to your mixer’s spare output, or put it near a speaker.
Step 2: Share the code
Print the pew card or show the code on screen. It never changes.
Step 3: Preach
Speak as you always do. Everyone reads or hears their own language.
The path of a sentence
One voice, carried to every pew.
The pastor speaks once. The sentence travels from the sound desk to every phone in the room, each in the language its owner chose, and to the big screen.
The sound desk
The pastor speaks English
mixer → laptop or phone
“Good morning, church.”

At the sound desk
Use the sound you already have.
No new microphones and no new speakers. Whatever your church already uses for the sermon is what we listen to.
Mixer aux or USB out
BestA spare aux send or the desk’s USB output gives the cleanest sound. Pick it as the input in the console.
An old phone at the desk
No laptop?A phone with a headphone-jack adapter does the same job from the mixer. Keep it on its charger.
Room mode
No mixer?Put a phone near a speaker. Room mode cleans up the sound; it works in halls and living rooms too.
Bring
- A laptop or phone, with its charger
- Internet: Wi-Fi or a hotspot
- 15 minutes before the service
On Sunday
One button, and the room follows.
What the sound desk does, and what people see on their phones, from before the first hymn to the benediction.
Hold to go live.
One button at the sound desk. Hold it for about half a second, so it never starts by accident.
Coming next
- Start on a schedule, so captions begin with the first hymn by themselves.
- A short note to the pastor on Monday: who listened, and what the team fixed.
Any language, any moment
Switch languages mid-sentence.
The pastor, an elder and the reader can each speak their own language, or mix two in one sentence. Everyone still reads their own. No one has to choose a language at the desk.
At the pulpit
Good morning, church. Welcome to our joint service — three congregations, one family.
In the pew
Buenos días, iglesia. Bienvenidos a nuestro culto unido: tres congregaciones, una sola familia.
Scripture
The words people know.
Scripture lock. When the pastor names a passage and reads it, phones and the big screen show the published text itself, from the Bible your church chooses for each language, labelled “Published text · not AI”, in English, Spanish, Korean, Cantonese and Mandarin.
A reading that wasn’t named first, and every other language, is translated in the terms of the Bible its readers know (和合本 for Chinese readers, 개역개정 for Korean, Reina-Valera for Spanish) and labelled AI. Your glossary keeps your church’s own words, like 神 or 上帝.
Public-domain Bibles for Scripture lock
- English
- Berean Standard Bible (BSB) · King James Version (KJV)
- 中文
- 和合本 (Chinese Union Version, 神 or 上帝 edition, Traditional and Simplified)
- 한국어
- 개역한글 (Korean Revised Version, 1961)
- Español
- Reina-Valera 1909
Licensed versions, such as 개역개정 and the Reina-Valera 1960, as agreements are signed.

And when this sound rang out, a crowd came together in bewilderment, because each one heard them speaking his own language.

Screens and livestream
On the wall, and on the stream.
Every room has a screen link. Paste it where you need it; your church’s link replaces <your-link>.
The big screen in the room
Large type in up to three languages, with the QR code on screen while people arrive.
voclyn.com/<your-link>/screen?langs=en,yue,zh-Hans&qr=1ProPresenter, as a web object
Captions as a lower third over your slides, on a transparent background.
voclyn.com/<your-link>/screen?layout=lower&bg=transparentOBS, as a browser source
Captions on your livestream. Two lines, transparent, or on a green key if your setup prefers it.
voclyn.com/<your-link>/screen?layout=lower&bg=transparent&lines=2
Captions on the big screen are always whole sentences, never words being typed. Nothing moves on the screen during the sermon.
For the sound desk
Technical questions.
The things AV volunteers ask us first.
Right away. The original words appear on every phone as the pastor speaks, and each sentence is translated right after it ends.
Captions use a few MB an hour of speaking. Listening with the AI voice uses about 11 MB an hour. Phones can use the church Wi-Fi or mobile data.
Any recent iPhone or Android phone, in the browser that opens when people scan the code. No app and no account. At the desk, use a recent Chrome, Edge or Safari on a laptop, or a phone.
Phones show “Reconnecting…” and catch up with what was said when the connection returns. At the desk, the console keeps the screen awake and reconnects by itself.
Yes. A room with Cantonese gets its own speech engine, so Cantonese isn’t mistaken for Mandarin, and it is captioned in Traditional Chinese. Mandarin readers get Simplified, or Traditional if they choose 國語.
Translation rests while the church sings. One tap at the desk, and phones show “Worship · captions resume when someone speaks”. We don’t translate song lyrics.
We don’t keep service audio. Transcripts are saved only if your room is set to save them, for as long as your plan keeps them. The listener page has no account, no cookies and no tracking.
