What it is
The WorshipHub desktop transcribes the preacher in real time. Captions takes that transcript and shows it on any phone in the room — and, if the listener picks a different language, translates it right there on their device.
The translation genuinely runs inside each listener's browser. Nothing is sent to a translation service, there is no per-minute cost, and it does not matter whether five or five hundred people are connected.
Opening the app
Nothing to install. Listeners open captions.worshiphub.live in their phone browser. It is worth putting that address, or the QR code, on a slide before the sermon starts.
Setting it up for a service
- 1On the WorshipHub desktop, download a Whisper speech model under Settings ▸ Live Translation (the Lite model is about 60 MB and fast; Pro is about 539 MB and more accurate).
- 2Enable Live Translation and pick the language the preacher will speak.
- 3Turn on Tools ▸ Captions App, then show the join QR on the projector with Tools ▸ Show Join QR.
- 4Listeners scan it, pick their reading language, and the transcript starts appearing.
The first time someone picks a non-English language, their phone downloads a translation model of about 15 MB. Ask people to join a few minutes before the sermon so that download happens while they're settling in, not mid-sentence.
If something goes wrong
The transcript is empty or frozen
Check that Live Translation is actually running on the desktop and that it is receiving audio. If the preacher is using a phone as the microphone, that phone needs to have the Predicador screen open and streaming.
Translation is slow on older phones
The model runs on the phone's own processor, so speed varies by device. The committed sentences catch up reliably; it is the in-progress phrase that may lag on an older phone.
A listener sees "Trust this device"
Same self-signed certificate flow as the other apps: tap Trust, accept the warning in the tab that opens, come back. Once per phone.
Can it read the text aloud?
Not right now. Text-to-speech existed in an earlier build but was inconsistent across phones, so it is hidden while it gets reworked. The code is still there — it will come back once it is genuinely reliable.
