🆕 NEW: HeyGen Avatar IV is here.
Our most advanced AI avatar model yet.
📸 One photo.
📝 One script.
🎧 Just your voice.
Most avatars sync to your words. Avatar IV interprets them.
Built on a diffusion-inspired audio-to-expression engine, it analyzes your vocal tone, rhythm, and emotion — then synthesizes photoreal facial motion with temporal realism.
🎭 Head tilts. Pauses. Cadences. Micro-expressions.
➡️ A single image → a video that feels real, not rendered.

Avatar IV is the first HeyGen model that doesn’t just sync to your voice — it understands it.
It captures the rhythm, tone, and intent of how you speak — driving natural facial expressions, subtle head movement, and micro-gestures in real time.
Powered by a neural audio-to-expression engine, Avatar IV predicts lifelike facial dynamics directly from voice — no motion capture, no rigging, no actor training. Just one photo.
Avatar IV makes your image move like you mean it.
