Hello,
English is the choice on the main page and the website is automatically in English when your browser parameter is in English. At least, it is suppossed to (tested under Chromium and Firefox with Linux).
I am going to add a link on all pages to go to the mainpage in English to avoid inconvenience.
This website present different solutions for different kind of handicap, but the solutions are not hosted here.
You are probably looking for this article : https://www.handilibre.org/site-librivox-112?lang=en which presents the website https://librivox.org/
So to contribute to audiobooks, you should go to the website https://librivox.org/
Thanks for your comment and please, tell me if you think adding a language link seems to bee suitable to solve inconvenience.
Ben
