The technology behind it
Voco uses a three-stage pipeline to turn spoken words into translated text for live delivery. Timing varies with the audio, network, and language pair.
Speech recognition
Live speech recognition designed to work best with a clean, direct audio feed.
Neural translation
Context-aware translation with custom vocabulary tools for names, scripture terms, and church language.
Voco for delivery
Built-in theological glossary, profanity filter, word boost, reconnect logic, and a reader interface designed for church.
Frequently asked questions
Does it work if my WiFi is unreliable?
Yes. Voco stores missed text server-side and delivers it the moment an attendee reconnects. They won't lose the thread of the sermon.
What languages does Voco support?
155+ languages including Spanish, Portuguese, French, German, Mandarin, Farsi, Arabic, Yoruba, Tagalog, and dozens more. See the full list on our Languages page.
Do attendees need to download an app?
No. Attendees scan a QR code and the reader opens in their phone's browser. No download, no account, no friction.
Can I use Voco with OBS or ProPresenter?
Yes. Add your Voco display URL as a Browser Source in OBS. On ProPresenter, use a Web Item. Translations appear as live lower thirds on any screen.
