Tested, dated and published.

• The original words appeared on the phones as they were spoken.
• Each sentence was translated right after it ended, in English, Spanish, Mandarin and Korean.
• Speech recognition made 1 error in 115 English words (“two” written “2”).
• Every part was labelled with the right language, including two sentences that switched language midway.

1. We wrote short sermon-like sentences and had a computer voice read them: English, Spanish, Mandarin and Korean, and two sentences that switch language in the middle.
2. Each recording was trimmed to the voice, with 0.6 seconds between sentences, as when a preacher barely pauses.
3. A script streamed the audio into the live system at speaking pace, through the same public demo anyone can try on our site, sending each tenth of a second when a microphone would have finished capturing it.
4. Every caption and translation was timed against the audio: from the moment a sentence ended to the moment its translation arrived.
5. Every timing is public, sentence by sentence: raw timings (CSV).

This is one test with a clean computer voice, two runs and one internet connection. A pulpit microphone in a room with an echo, music in the background and a preacher who never pauses will be slower; and so is a preacher who barely pauses.

We haven’t measured Cantonese rooms (they use a separate speech engine), the AI voice, or busy church Wi-Fi with a hundred phones. Next we will measure real services at pilot churches, with their permission, and publish those numbers here with their dates.

This is not a comparison with other products. We haven’t tested them, so we don’t claim to be faster than anyone.

Every translation on a listener’s phone is labelled AI, except Bible readings shown from a published Bible, which are labelled “Published text · not AI”. A passage is shown only when it was named and what follows is mostly its words; a paraphrase gets no card, because a wrong verse is worse than none.

We don’t publish an accuracy percentage yet. The next test checks what churches care about most: pastors’ names, church words and Bible books, with and without the glossary.
