LibriVox is an invented word inspired by Latin words liber (book) in its genitive form libri and vox (voice), giving the meaning BookVoice (or voice of the book). The word was also coined because of other connotations (although not based on proper grammar) as liber also means child and free, independent, unrestricted. As the LibriVox forum says it: "We like to think LibriVox might be interpreted as 'child of the voice', and 'free voice'.
