How This AI Model Generates Singing Avatars From Lyrics

This article explores a sophisticated AI system designed to generate full-body rap performances—including vocals, gestures, and lip sync—based solely on input lyrics. It breaks down the model architecture, including VQ-VAEs for motion and vocal tokenization, and a T5-based autoregressive framework. Evaluation metrics, ablation studies, and ethical considerations are also discussed, with a demo showcasing how AI can synthesize lifelike, expressive virtual performances from text prompts.
