In case anyone needs it, I recently created a plugin called Runtime MetaHuman Lip Sync that enables lip sync for MetaHuman-based characters across UE 5.0 to 5.5. It supports real-time microphone capture with lip sync, separate capture with lip sync during playback, and text-to-speech lip sync.
Here’s a video demonstrating all three features and how to set them up using the plugin: https://www.youtube.com/watch?v=ZYP--BKY7XI
