Me too. That sounds quite interesting! Added to my Steam wishlist.
They exist. When I was big into sub simulators, I came across a review of Lonewolf (a sub simulator designed for the blind) that I found pretty amazing. It seems to rely upon a screen reader for speech (or at least it did - it requires Windows 95 or higher, so probably about 20 years old) rather than having recorded voices unfortunately, but the idea that I could still play sub simulators even if I lost my sight really made me happy.
