Word-Level Timing for Real-Time Avatars
HeyGen · x · 2026-07-15
HeyGen shared an article regarding word-level timing for real-time digital avatars. The core issue is that when an avatar is speaking and acting simultaneously, actions must align perfectly with specific words, or the illusion shatters instantly.
The article emphasizes that once real-time speech and motion are bound, timing control becomes the make-or-break factor for the system: interactive actions like clicking, scrolling, and annotating must align perfectly with spoken words to make the avatar look natural and coherent.
