I've seen a few comments saying that vim doesn't work that well with screen readers. But you could probably use a Vim plugin for Emacs so that you can still make use of EmacsSpeak. The other famous Emacs joke is that it's the best Vim editor :) I just read that Eclipse is supposedly also a nice choice for blind people. I wonder how Intellij compares, their website says it's best to use it with Windows, only works "to some extend" on macOS and Linux isn't even mentioned, so on Linux Eclipse might be the better choice.
