Vietnamese and English, on every phone.

Some churches put the sermon on everyone’s phone with Microsoft Translator’s Presenter mode. In January 2025 one church user wrote on Microsoft Q&A that they had used it since March 2023 to turn spoken Vietnamese into text on listeners’ phones, mostly in English, and asked for something that worked the same way. On 30 June 2026, the Translator app’s release notes for version 26.7.1.2 said its multi-device conversation feature had been retired.

Voclyn does that job for a church service. Instead of a conversation code, the church has its own link and QR code, the same every week; people scan it, choose English or Tiếng Việt and read, with no app or account. Voclyn detects the language spoken at the front, so a Vietnamese sermon with English announcements needs nobody switching languages. Microsoft Translator alternative for churches.

A Vietnamese church with English-speaking youth

The pastor preaches in Vietnamese. Young people and guests who read English more easily follow the sermon in English on their phones.

An English church with Vietnamese-speaking families

The sermon is in English. Parents and grandparents read it in Vietnamese, with full diacritics, or on paid plans listen to an AI voice in Vietnamese through earbuds, labelled as AI.

Several languages at once

The same QR code offers 100+ languages to read, so a church with Vietnamese, Spanish and Chinese members can caption the service for each at once. Voclyn hears Vietnamese at the front and detects it by itself, even when the speaker switches mid-sentence. How language switching works.

Vietnamese captions use Protestant terms unless your glossary says otherwise: Đức Chúa Trời for God, Đức Chúa Giê-xu Christ, Đức Thánh Linh for the Holy Spirit and Hội Thánh for the church. A Catholic parish adds its own words to the glossary, such as Thiên Chúa for God and Thánh lễ for the Mass, and every caption follows them.

There is no Vietnamese starter pack yet, so start with what people notice first: your pastors’ names, your church’s name and the words your tradition uses. Glossary terms are used both when Voclyn hears and when it writes.

Lines from the sample service in our demo; on a phone, every translated caption is labelled AI.

Free translates 6 hours a month into 1 language plus your main language, on phones, with no time limit: a Vietnamese church with English for its young people fits. Paid plans translate every service (fair use) and add the AI voice and the big screen. Free, then $69, $99 or $249 a month (C$99, C$139, C$349); listeners never count. See the plans.

• No published Vietnamese Bible: when the pastor reads a passage, Vietnamese readers get it translated like the rest of the sermon, labelled AI. Verse cards from published Bibles cover English, Spanish, Korean, Cantonese and Mandarin readers today. About Scripture lock.
• The listener page’s own buttons are in English for Vietnamese readers; the captions are in Vietnamese.
• There is no Vietnamese glossary starter pack.
