What is ai_voiceoverdata_wotlk?

This is a data pack for World of Warcraft, specifically the Wrath of the Lich King version of the game (Classic Era, patch 3.3.5). It does not contain any playable game code or an addon by itself. Instead it holds AI generated voice audio files and lookup tables that tell a separate addon, called AI_VoiceOver, which sound clip to play for which quest and NPC. Without that addon already installed, the voice files in this repository do nothing. The voice lines were generated using Qwen3-TTS, an open source text to speech model that runs locally, with voice samples cloned per race and gender so different types of characters sound distinct from one another. The author aims to cover quests across every zone in the expansion, though the README admits this is a work in progress and that some NPCs without a matching voice sample will default to a generic narrator voice instead. Setup is simple: install the AI_VoiceOver addon into the game's AddOns folder first, then copy this pack's folder into the same location. There is no build step, no compiling, and no other dependencies described. The credits point to the addon's original author, the Qwen3-TTS model, and the AzerothCore project for supplying the quest and NPC database this pack is built against. The README itself is short and sparse beyond the setup steps, credits, and a request for players to report any quest that plays no audio. The project is explicit that it is a fan made, non-commercial project. All the voice lines are AI generated rather than original recordings from the game's publisher, and World of Warcraft is stated as a trademark belonging to Blizzard Entertainment, not to this project's author.
