HeyGen has just launched Avatar IV, a powerful new AI model that brings real emotion and lifelike movement to animated avatars using just a single photo and your voice.
This isn’t your typical talking avatar. Avatar IV listens to how you speak and responds with natural facial expressions, subtle gestures, and emotional nuance that makes it feel truly alive.

The most advanced avatar model we’ve ever built.
Upload one photo and a script. That’s it.
Our new audio to expression engine captures your tone, rhythm, and emotion, then generates facial motion so real it feels alive.

- Emotion from Audio: A new audio-to-expression engine turns your voice into realistic micro-expressions, facial motion, and hand gestures.
- One Photo, Endless Possibilities: Avatar IV works with side angles, anime characters, pets, and more. All it needs is one image and a script.
- Full-Body Flexibility: Create portrait, half-body, or full-body animations—no more being stuck with stiff talking heads.
- Creator-Ready: Perfect for influencers, singers, gamers, podcasters, and anyone who wants to make professional-looking content without cameras or actors.
Why It Matters
With Avatar IV update, HeyGen takes a big leap forward. Instead of robotic or emotionless avatars, you get characters that react and feel—adding depth and realism that changes how we think about AI video content.
Whether you’re making short videos, virtual podcasts, or storytelling with AI, this opens up a whole new world of creativity.
