HeyGen has launched Avatar IV, an AI avatar that mirrors tone, emotion, and micro-expressions in real time. It makes virtual conversations feel more lifelike and responsive.

With this update, digital avatars react more naturally—just like real people. Whether for virtual assistants, video content, or presentations, Avatar IV helps users create more human-like and emotionally aware interactions.

Emotionally Intelligent Avatars From A Single Photo

HeyGen’s Avatar IV builds lifelike avatars using just a single photo and a voice or script input. It’s designed to capture tone, rhythm, and emotional cues with striking realism.

In the tweet below, HeyGen explains how its audio-to-expression engine interprets vocal details to generate natural movements—like head tilts, pauses, and subtle expressions—that make the avatar feel human:

The result is a video that feels spontaneous, not scripted. Users can easily create emotionally aware content without complex tools or multi-image setups.
