• Title: Audio2Rig: Artist-oriented deep learning tool for facial animation
• Authors: Bastien Arcelin, Nicolas Chaverou,
• Abstract summary: Audio2Rig is a new deep learning tool leveraging previously animated sequences of a show, to generate facial and lip sync rig animation from an audio file. Based in Maya, it learns from any production rig without any adjustment and generates high quality and stylized animations. Our method shows excellent results, generating fine animation details while respecting the show style.

• Abstract: Creating realistic or stylized facial and lip sync animation is a tedious task. It requires lot of time and skills to sync the lips with audio and convey the right emotion to the character's face. To allow animators to spend more time on the artistic and creative part of the animation, we present Audio2Rig: a new deep learning based tool leveraging previously animated sequences of a show, to generate facial and lip sync rig animation from an audio file. Based in Maya, it learns from any production rig without any adjustment and generates high quality and stylized animations which mimic the style of the show. Audio2Rig fits in the animator workflow: since it generates keys on the rig controllers, the animation can be easily retaken. The method is based on 3 neural network modules which can learn an arbitrary number of controllers. Hence, different configurations can be created for specific parts of the face (such as the tongue, lips or eyes). With Audio2Rig, animators can also pick different emotions and adjust their intensities to experiment or customize the output, and have high level controls on the keyframes setting. Our method shows excellent results, generating fine animation details while respecting the show style. Finally, as the training relies on the studio data and is done internally, it ensures data privacy and prevents from copyright infringement.

For temporal control, we replace the global temporal attention of the original T2V model with our proposed positional-corrected window attention.

  DIRFA is a novel method that can generate talking faces with diverse yet realistic facial animations from the same driving audio.

We show that DIRFA can generate talking faces with realistic facial animations effectively.
