The audio is not synthesized from the text, it is a recording of a human voice. YouVersion does not actually record any of the audio available in the app. Our partners record the audio and then make it available to us for free so that we can provide it to you for free. In many cases, only the New Testament or certain books of a Bible version have been recorded.
Even though only certain versions or portions of versions are available at this time, you can rest assured that everything that we have, we’re sharing with you and the YouVersion community.
YouVersion does not own the copyrights for any of the audio versions that we offer. It’s only through cooperative partnerships with generous Bible societies and publishers that we are able to use the many versions that we do. The organizations who provide YouVersion with the versions that we have available have demonstrated extraordinary grace and generosity in allowing us to bring them to a worldwide audience—completely free of charge. In fact, their choice to partner with us makes possible everything that we do. And we are profoundly grateful for each of these relationships.
