I use Windows. I chose a product called TextAloud from
NextUp. I mainly chose this for the many different voices I could get. In theory TextAloud is supposed to open ePubs, in practice it never seems to work for me, but I don't care that much. I don't edit epub directly other than tidy-up, all text changes happen against my original source. Also I find proof-reading is best done in short doses, so I simply copy an paste one scene at a time into the TextAloud window.
