The spoken audio of the Readings at Mass and of the Liturgy of the Hours is available on subscription. It is very simple to use. If you haven’t tried it before, do! You can listen to a sample before you subscribe.
How it works is this: you press the Play button, and a real, recorded human voice will speak the whole of the page you are looking at: the readings at Mass or one of the Hours. A yellow highlight follows the spoken lines and sentences, so you always know where you are.
You can read more about it all here for Android and here for iPhone and iPad.
The purpose of this blog post is to go just a little below the surface so that you can understand how it all behaves.
