Core Dialog - Local NPC Talk AI

Core Dialog is a fully local AI communication framework for Unity that enables NPCs to listen, reason, and speak in real time without internet access. It combines Speech‑to‑Text, Large Language Model, and Text‑to‑Speech capabilities using LlamaSharp, Whisper.net, and Pocket TTS. The system supports both typed input and voice commands, tracks context and world data such as inventory or location, and includes emotional and relationship variables that affect dialogue outcomes. Developers can generate custom NPC voices by uploading a 5‑second audio clip. The asset provides modular prefabs, extensive documentation, and demo scenes illustrating a shopkeeper, a companion, a hostile enemy, a generic chatbot, and a voice‑cloning sandbox.
