In this tutorial, I demonstrate how to set up high-quality, realistic lip synchronization for MetaHuman characters created with the new MetaHuman Creator system in Unreal Engine 5.6, using your microphone’s live audio input. This method delivers superior visual fidelity with immediate response to your voice, working completely in real-time and functioning in packaged projects.
