Have you tried having him scan the page for words he doesn't know first and sound them out/look them up before he reads anything? Then he could read more seamlessly. This sort of pre-reading is something I recommended for my college students, so it's a useful skill for anyone to learn.

If he has trouble remembering the words, he could even mark them on the page (if you write in books at your house) or write the words down on a separate sheet of paper.

Maybe helpful, I hope?
