About Heartongue
Heartongue is a browser-based live interpretation service for Catholic parishes, multilingual churches, and Christian events. A speaker talks through a laptop or connected microphone; the service produces translated captions and AI-generated speech for listeners in their chosen languages. Attendees join by scanning a QR code on their phones, without installing an app or creating an account. The service supports 49 languages and automatically detects language changes. Church-focused features include Bible readings in listeners’ language editions, terminology tailored to Catholic or Protestant traditions, familiar wording for common prayers, and a glossary organizers can edit. Presenters can monitor a broadcast, while captions can be shown on a screen or added to a livestream through an OBS browser source. Heartongue is designed for worship services and other gatherings where participants need real-time multilingual access.
