Many centuries ago it was quite normal to read aloud, it was the normal way. In the days of the North African bishop Aurelius Augustinus a change was noticed. People started reading in a quiet voice. Maybe lips were moved, but not a sound was heard.  

Often children like to be read to, to hear the voice of father or mother or an elder sibling. On the World Reading Aloud Day 2018 children will also be read to by well known people, for instance in South Africa. Read (aloud) about it here.
