I remade Voiceover.uax too.
Try new version of all the files and subtitles.int
https://disk.yandex.ru/d/_jCH19BlnO53ew

It's not the final version, I'm thinking of these lines:
A04_ScaryVoice01=(scary inaudible talking) &d=2.5
A04_ScaryVoice02=(scary inaudible talking) &d=3.2
A04_ScaryVoice03=(scary inaudible talking) &d=3.0
A04_ScaryVoice04=(scary inaudible talking) &d=3.7
A04_ScaryVoiceLong01=(scary inaudible talking) &d=6.0
A04_ScaryVoiceLong02=(scary inaudible talking) &d=7.0

Maybe change them to something like:
Terger tsal ruoy eb dluow i
Em mrah tonnac uoy


My theory for the bug is: if more than one sound is played at the same time and this sounds marked as subtitled - their subtitles overlap. Even if there are no subtitle lines in subtitles.int

So now only sounds with rows in Subtitles.int have subtitles flag enabled in uax files

New version of subtitles

Thanks to J222 one rare bug was fixed for this sounds
1mon_007
1mon_008
1mon_020
Pa_086
Pa_142
Pa_123
Pa_032

For some reason subtitles flag for them needed to be in 10th not 11th byte before RIFF header.
Also a lot of mistakes were fixed in Subtitles.int

I have a problem with the intro. Instead of line 109, line 107 is displayed again.
With the old subtitles.int it looked like this:

Pa_107=I fled Ireland and wandered around Paris and London with no real destination until the Great War began. &d=5.5
.....
Pa_109_1=We were ambushed! They came out of the woods waving swords and howling like banshees. &d=6.0
Pa_109_2=I saw their leader holding a strange stone above his head... and shouting strange words in a foreign language, &d=8.5
Pa_109_3=and just as I was about to pull the trigger, he stared at me. &d=3.5
Pa_109_4=A bright green flash came from his hand, and it boiled over me as my gun went off. &d=5.5
Pa_109_5=I woke up in a hospital bed with severe burns. I was told Jeremiah and the unit had gone on without me, &d=7.5
Pa_109_6=but he had given me the shaman's stone to keep.... &d=4.5

in the current version like this:

Pa_107=I fled Ireland and wandered around Paris and London with no real destination until the Great War began. &d=5.5
.....
Pa_109=We were ambushed! They came storming out of the forest, waving swords and howling like the plague. &d=6.0
Pa_109_1=I saw their leader holding a strange stone above his head... and shouting strange words in a strange language, &d=8.5
Pa_109_2=and just as I was about to pull the trigger, he stared at me. &d=3.5
Pa_109_3=A bright green flash emanated from his hand, and it boiled over me as my gun went off. &d=5.5
Pa_109_4=I woke up in a hospital bed with severe burns. I was told Jeremiah and the unit had gone on without me, &d=7.5
Pa_109_5=but he had given me the shaman's stone to keep.... &d=4.5

if I change it back to the old version, the text is displayed correctly again.
I don't know if the designations were also changed in other places and maybe cause problems?

I reversed changes for Pa_109 and Pa_110 to solve this bug.

Also, finally Sed_003 lines were transcribed
Link is the same. I really hope this time everything works fine......

Good gravy, thank you! To all of you! You just made the game way more accessible to people. For clarification is this subtitles patch just for English or does it include even the other languages/fan translations subtitles? (I assume that's not possible, but heck I'm already impressed every single voice line in the game *could* be subtitled via modding in the first place).
Again, thank you!!!

This is for English only. Patches for some other languages can be found here:

Great work! Thanks for the English subtitles. Are these compatible with the Undying Revival 1.1.2.3 Mod? They were working fine until I installed the Revival mod, now they don't appear anymore which is a shame. Any thoughts on why they are no longer showing?

Thanks!
:)
