The Live Avatar model performs very well in terms of visual quality and lip synchronization. The lip sync is accurate and aligns well with the audio, making speech appear natural and convincing.
However, there is a noticeable issue with body dynamics—specifically hand gestures and head movements.
Problem Details:
Hand movements are excessively fast and lack natural easing.
Head movements (neck rotation, nodding) appear jittery and overly reactive.
Combined motion creates a robotic or artificial appearance instead of a human-like flow.
Expected Behavior:
Smooth, natural gesture transitions with proper motion easing.
Human-like timing for head and hand movements (slight delays, inertia, and subtle variation).
Balanced synchronization between speech and body gestures.
Actual Behavior:
Overly rapid gesture execution.
High-frequency motion changes causing visual instability.
Avatar appears robotic despite good facial realism.
