The Cathedral of Santiago has unveiled a simultaneous translation service developed thanks to AI.

This is a mobile phone application that, relying on artificial intelligence, translates in real time all the content of the mass celebrated on the high altar, without interfering in the mass or altering the solemnity of the environment. Thanks to this app, you can follow the mass with digital translation, in text and audio making it perfect for pilgrims of any language or with hearing impairments. 
It's free and available on the App Store and Google Play - search your country's app store if you are not in Spain. 

The app is available for Android or Apple devices.
