Realization details of motion control technology
FantasyTalking's Motion Intensity Modulation Module uses deep learning techniques to analyze audio spectral features and map them into 72 facial blend morphology parameters. The module has:
- Audio feature decoupling capability to separate speech content from emotional features for processing
- Multi-level intensity control system with adjustable amplitude of limb movements via the -audio_weight parameter (0.1-1.0 range)
- Real-time feedback mechanism to ensure precise correspondence between movement changes and audio tempo
This technique is particularly suitable for virtual anchor scenarios, e.g. higher intensity values (0.8+) can be set when delivering arousing content, whereas teaching scenarios are suitable for medium intensity (0.4-0.6). The system ensures that the motion accuracy of key areas (e.g., lips) is better than the traditional scheme of 30% or more through the attention mechanism.
