Heartongue interprets Mass, homilies and sermons live, like an interpreter in the booth. Each listener scans a QR code and follows on their own phone, with a natural voice and captions in their language. No headsets, no app to install. It translates the way their church speaks: Bible verses from their own Bible, Catholic or Protestant words by tradition, prayers as the parish prays them. 49 languages, about two seconds behind the speaker.

Could you build this?

Partial The listener UI (QR join, phone captions, multilingual playback) is vibe-codeable, but live, low-latency speech translation with accurate liturgical and scriptural terminology is hard to get right.

What it would actually take: Architecture would chain streaming speech-to-text, a translation model, and streaming TTS over WebSockets, with a QR-based session layer. The hard parts are sub-few-second latency at scale and terminology accuracy for Bible quotations, liturgy, and doctrine, which needs curated glossaries and ideally review by bilingual theologians or interpreters.
