No more preaching twice.

A Chinese church may gather three congregations under one roof, 粵語堂, 國語堂 and 英文堂, each with its own Sunday service. One church in San Francisco’s Chinatown lists them back to back: Mandarin at 9:30, English at 10:45 and Cantonese at noon. In Vancouver, St Chad’s Anglican began its Chinese service as one combined service with earphones for translation, then split it into Mandarin and Cantonese services.

With Voclyn the congregations can worship together whenever they choose. The pastor preaches once; each person scans the church’s QR code and reads in 廣東話, 國語, 普通话 or English, or listens. A joint service at Easter, Christmas or the church’s anniversary no longer has to run twice as long.

Without translation on phones, a joint service often means a relay. A 2008 account of one Chinese Alliance church describes it: the pastor preached in Mandarin, his wife relayed each section in Cantonese on stage, and an interpreter repeated it in English over radio earpieces for those who understood neither. Every point is made two or three times.

With Voclyn the pastor preaches once, at the usual pace, and may move between the three languages, even mid-sentence. Voclyn detects each phrase, and every phone shows it in its reader’s language, or as said when it is already theirs. How language switching works.

If your interpreter keeps relaying for a while, Voclyn captions the relay too. In rooms that include Cantonese, the labels that tell speakers apart aren’t available yet, so readers see the sermon and the relay one after the other.

The speech engine most rooms use hears Cantonese and Mandarin both as Chinese. So a room that includes Cantonese uses a second engine, one that hears Cantonese as Cantonese, for the whole service, and it hears Mandarin and English too.

What the pastor says in Cantonese is shown to Cantonese readers as said, in Traditional characters. What is said in Mandarin or English is written for them in standard written Chinese with Hong Kong characters, not in colloquial characters such as 嘅 or 喺. Cantonese church translation.

• Three ways to read Chinese. 廣東話 in Hong Kong Traditional characters, 國語（繁體） in Traditional characters as in Taiwan, and 普通话（简体） in Simplified characters, each with the page’s buttons in the same script. Mandarin church translation.
• Large text for elders. Captions grow up to 42 px, with a dark theme for the sanctuary.
• Listen instead of reading. On paid plans an AI voice reads the captions in Cantonese or Mandarin through earbuds, labelled AI 語音, and keeps playing with the phone locked. It runs a few seconds behind the captions (our estimate) and uses about 11 MB an hour.
• Nothing to sign up for. No app, no account, no cookies or tracking, and the page never uses the phone’s microphone, camera or location.

Choose once how your church writes God, in Settings or the glossary: 神, 上帝 or 天主. Every translated caption follows it, in every Chinese script; without it, our own test on 29 October 2026 wrote God as 上帝 in one sentence and 神 in the next. Starter packs fill the rest of your tradition’s words in Traditional and Simplified: 聖靈、崇拜、聖餐、團契、弟兄姊妹, or 聖神、彌撒、神父 and the 思高 names for a Catholic church.

When the pastor names a passage and reads it, Chinese readers see it from the 和合本, the most widely used Bible in Chinese Protestant churches, marked 出版譯本 · 非 AI 翻譯 (Published text · not AI). Your church chooses the edition for each room in Rooms › Languages, the 神 edition or the 上帝 edition, so verse cards and captions use the same word. How Scripture lock works.

On paid plans the projector can show Cantonese, Mandarin and English as three bands, whole sentences only, with the church’s QR code while people arrive:
