Unison: Harmonizing Motion, Speech, and Sound for Human-Centric Audio-Video Generation

Chi Zhang, Jiaxu Zhang, Quanyue Song, Shansong Liu, Shihao Cheng, Xiaolei Zhang, Xuelong Li, Zhigang Tu, Zhizhi Guo

Unison is a unified framework that harmonizes motion, speech, and sound in human-centric video generation through explicit multimodal strategies.

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

Unison achieves state-of-the-art performance in both audio perceptual quality and cross-modal synchronization, highlighting the importance of explicit multimodal harmonization in human-centric video generation.

C2weakest assumption

That the proposed semantic-guided harmonization strategy and bidirectional cross-modal forcing with decoupled denoising schedules will reliably improve coherence without introducing new artifacts or requiring extensive post-hoc tuning on specific datasets.

C3one line summary

Unison introduces a unified framework using semantic-guided harmonization and bidirectional cross-modal forcing to generate human-centric videos with improved synchronization between motion, speech, and sound effects.
