The Vatican introduces an AI-assisted live translation service

The Vatican has launched an AI-powered live translation service for Holy Mass at St. Peter’s Basilica, enabling attendees to follow the liturgy in 60 different languages. This initiative, developed in partnership with the language service provider Translated, marks the first large-scale use of AI interpretation within a sacred space at the Vatican. The technology, called Lara, leverages advanced AI translation tools supported by over 500,000 native-speaking professional translators to ensure sensitivity and accuracy. Attendees can access the translations via their smartphones by scanning QR codes placed at the entrance and various points inside the basilica, receiving real-time audio and text translations of the Mass.

This service aligns with the Vatican’s mission of universality, making its religious ceremonies more accessible to a global audience. Cardinal Mauro Gambetti, Archpriest of the Papal Basilica of Saint Peter, emphasized that the technology serves the Church’s fundamental vocation by breaking down language barriers. The project has also benefited from the scientific guidance of Professor Alexander Waibel, a leading expert in AI speech translation, who highlighted the significance of real-time language interpretation in such a meaningful setting. The initiative coincides with the celebrations of the fourth centenary of the dedication of Saint Peter’s Basilica, underscoring the Vatican’s embrace of innovative technology to enhance spiritual participation and understanding worldwide.
