It is a sound library that is used by the Modern VoiceOver addon, adding immersion to the classic gameplay with voices generated directly from the games original sound files.
Modern VoiceOver adds spoken dialogue for all quests / items / gossip / and objects in the game.
When the player interacts with an NPC or object, rather than being greeted with a wall of text, the dialogue will be spoken with an AI generated voice, cloned from the games original sound files to seamlessly integrate with the game.
This library provices the sound files for all gossip and quests dialogue from Tauren and Undead NPC's.
You will need all 5 sound packs (Alliance, Alliance2, Horde, Horde2 Extras) for a complete experience.
