It's forked from DBM and added some useful features like voice warnings for all the crucial events, hudmaps and arrows to help you realize things during the encounter, etc, etc.
You should be able to find it by searching "Voice Encounter Mods" on Curse.
Would be appreciated if anyone wanna have a try and give some feedback.
