There is a patch to Brogue 1.7.4 called Broguespeak which adds accessibility features using eSpeak speech synthesis: https://www.reddit.com/r/roguelikes/comments/4zjg48/broguespeak/. It would be amazing to get this or equivalent functionality integrated into CE.

First, we need to inspect the diff of Broguespeak against 1.7.4. We need to assess both its general quality/maintainability, and how much it conflicts with current CE. Issues with this either of these will require changes, though minor code quality issues can be fixed after merging. Additionally, this patch adds a new dependency, so that will have to be integrated into CI and build processes.
