There's something called ‘speak selection’. Once enabled in settings, you select text normally as if you were going to copy and paste it, then in the bar that pops up (which says 'copy', 'paste, 'select all', etc), they'll be a button that says 'speak'. Click that and it will read to you. If you can't read the text on the buttons to press that, how I do it is just by learning how many buttons along the 'speak' button is.
There's also a feature — which I only just learnt about whilst having a look for you — called ‘speak on touch’ which looks a lot more like what you're describing. When enabled in settings, they'll be a small button that you can move around the edge of you screen. If you press and hold it for a few seconds, it will read the entire screen. If you double tap it and then drag your finger around, it will read what your finger is hovering over.
