How did you get your child to recognize names ?

My son is 23 months. Can count to 20, knows his entire alphabet, knows all the lyrics to every song and knows all of his colors. But I cannot get him to recognize who he or anyone else is to him. I have been narrating everything I do and calling everyone by their name. I also show pictures of everyone in his life. He repeats or names so many objects he sees, except for people or anything he wants or needs. What techniques worked for this community? What can I do while I am on a 2 year wait list for intersection here in my city.
