Oh, hey, I ended up doing this recently too! I was too lazy to find software (I may try yours), so I've just ...been plugging into Google Translate and using the read aloud functionality xD

I found it good for the little errors and some flow things, and that it's good for giving me a little more distance from the work. And some parts of it feel very passive to me in a way that reading doesn't! The other good thing for me is that there are a lot of things that I might pick out if I were reading my own writing, but it turns out that when I listen to them read aloud, they doesn't bother me. So it's curbing the perfectionism a bit for me

Also, much easier to edit while petting cat.
