In this video, I showcase a complete speech-to-speech + lip sync workflow demo project for Unreal Engine that integrates voice recognition, AI chatbot responses, text-to-speech, and realistic lip synchronization. This demo demonstrates how multiple plugins work together to create a fully interactive conversational AI system with MetaHuman characters, supporting multiple languages including English, Chinese, Spanish, Japanese, German, French, and more.
