How to make the voice work correctly:
1. Open the MEGA file you downloaded.

(IF YOU'VE ALREADY DONE THIS, SKIP COPYING THE FOLDERS)
2. CREATE A COPY OF THE EXISTING CHARACTER VOICES!! It's at "[Drive with Steam]\Program Files (x86)\Steam\steamapps\common\Left 4 Dead 2\left4dead2\sound\player\survivor\voice\[character here]" & "[Drive Here]\Program Files (x86)\Steam\steamapps\common\Left 4 Dead 2\left4dead2_dlc1\sound\player\survivor\voice\[character here]"
You should have [character] - Copy in case you want to go back to the original.

(IF YOU ALREADY DELETED THE OLD AUDIO, SKIP THIS PART)
3. Leave the copied version of the folder alone, and DELETE EVERYTHING INSIDE THE CHARACTER FOLDER FOR BOTH NORMAL & DLC VERSIONS.

4. With the file still open, place EVERY SOUND FILE INSIDE (DLC IS FOR THE "left4dead2_dlc1" VERSION)
And then start left4dead 2, type in console "snd_rebuildaudiocache"
When it reaches 100%, type "quit" on the console and it's ready.

5(If you want to go back). Delete the character folders with the newly added audio, RENAME the [character] - Copy folders back to the original, then start left4dead 2, type in console "snd_rebuildaudiocache"
When it reaches 100%, type "quit" on the console and it's fixed.
