My partner is low vision and back in the day the Kindle app used to offer you the option to read a book out loud. This seems to be missing from both the app and the low end Kindles now. The only option seems to be to buy a $400 Kindle fire. Has anyone had any experience or does anyone have any advice on a way to get the app to read aloud the way it used to?

He is quite frustrated because he owns quite a few Kindle books that he has bought over the years and is no longer able to read them. Amazon seems to be quite happy to give away free books as long as you're sighted, there doesn't seem to be anything beyond the Kindle fire that would be useful to him.
