Digen.ai Unveils Lip Motion Gen-3: Next-Gen Audio-Driven Single-Character Video Synthesis—Ushering in a New Era of Hyper-Realistic Digital Humans

Digen.ai proudly introduces Lip Motion Gen-3, a groundbreaking AI model designed to generate high-quality single-character videos using only audio input. Leveraging our proprietary L-ROPE method—which integrates adaptive character positioning and semantic-aware label encoding—Gen-3 achieves remarkable improvements in lip-sync accuracy and facial expressiveness.

Combined with a partial-parameter fine-tuning strategy and multi-task learning framework, Gen-3 delivers exceptional instruction adherence and high-fidelity video output, even under limited computational resources.

From virtual YouTubers and educational content to personalized messaging and game character animation, Gen-3 opens up new possibilities for immersive digital storytelling. We are committed to making professional-quality avatar video generation more accessible and efficient than ever.

Although challenges remain in bridging the gap between synthetic and real voice audio, Gen-3 represents a significant leap toward photorealistic and emotionally responsive AI-generated video.

🏆 Industry-Leading Benchmark Performance

Gen-3 was rigorously evaluated across multiple internationally recognized datasets:

• Talking Head Datasets: HDTF, CelebV-HQ
• Talking Body Datasets: EMTDT

Comprehensive metrics were used:

• FID / FVD for visual quality
• E-FID for facial naturalness
• Sync-C / Sync-D for audio-lip synchronization

In comparative tests against leading solutions like AniPortrait, VExpress, and EchoMimic, Gen-3 outperformed competitors across key metrics—especially in lip-sync precision and video clarity.

Qualitative results further demonstrate Gen-3’s ability to interpret complex prompts such as “a man closing his laptop” or “a woman putting on headphones and smiling,” generating smooth motions with minimal visual artifacts.

🧠 Technical Innovations

• Architecture: Built on a Diffusion-in-Transformer (DiT) backbone with integrated 3D-VAE for efficient spatiotemporal compression.
• Multi-Modal Conditioning: Text prompts are encoded into embeddings, while CLIP-extracted image features provide contextual guidance via decoupled cross-attention.
• Audio-Visual Fusion: Gen-3 natively supports audio conditioning through specialized cross-attention layers. Wav2Vec-extracted audio embeddings are aligned with video latent frames using a novel audio adapter, resolving temporal mismatches seamlessly.

This end-to-end design ensures superior lip-sync quality and expressive consistency, setting a new standard in AI-driven digital human synthesis.
