## 📖 Introduction



Audio-driven portrait animation has made significant advances with diffusion-based models, improving video quality and lipsync accuracy. However, the increasing complexity of these models has led to inefficiencies in training and inference, as well as constraints on video length and inter-frame continuity. In this paper, we propose JoyVASA, a diffusion-based method for generating facial dynamics and head motion in audio-driven facial animation. Specifically, in the first stage, we introduce a decoupled facial representation framework that separates dynamic facial expressions from static 3D facial representations. This decoupling allows the system to generate longer videos by combining any static 3D facial representation with dynamic motion sequences. Then, in the second stage, a diffusion transformer is trained to generate motion sequences directly from audio cues, independent of character identity. Finally, a generator trained in the first stage uses the 3D facial representation and the generated motion sequences as inputs to render high-quality animations. With the decoupled facial representation and the identity-independent motion generation process, JoyVASA extends beyond human portraits to animate animal faces seamlessly. The model is trained on a hybrid dataset of private Chinese and public English data, enabling multilingual support. Experimental results validate the effectiveness of our approach. Future work will focus on improving real-time performance and refining expression control, further expanding the framework’s applications in portrait animation.



## 🧳 Framework



![Inference Pipeline](assets/imgs/pipeline_inference.png)



**Inference Pipeline of the proposed JoyVASA.** Given a reference image, we first extract the 3D facial appearance feature using the appearance encoder in LivePortrait, and also a series of learned 3D keypoints using the motion encoder. For the input speech, the audio features are initially extracted using the wav2vec2 encoder. The audio-driven motion sequences are then sampled using a diffusion model trained in the second stage in a sliding window fashion. Using the 3D keypoints of reference image, and the sampled target motion sequences, the target keypoints are computed. Finally, the 3D facial appearance feature is warped based on the source and target keypoints and rendered by a generator to produce the final output video.

## 🎒 Prepare model checkpoints



Make sure you have [git-lfs](https://git-lfs.com) installed and download all the following checkpoints to `pretrained_weights`:



### 1. Download JoyVASA motion generator checkpoints



```bash

git lfs install

git clone https://huggingface.co/jdh-algo/JoyVASA

```



### 2. Download audio encoder checkpoints



We suport two types of audio encoders, including [wav2vec2-base](https://huggingface.co/facebook/wav2vec2-base-960h), and [hubert-chinese](https://huggingface.co/TencentGameMate/chinese-hubert-base).



Run the following commands to download [hubert-chinese](https://huggingface.co/TencentGameMate/chinese-hubert-base) pretrained weights:



```bash

git lfs install

git clone https://huggingface.co/TencentGameMate/chinese-hubert-base

```



To get the [wav2vec2-base](https://huggingface.co/facebook/wav2vec2-base-960h) pretrained weights, run the following commands:



```bash

git lfs install

git clone https://huggingface.co/facebook/wav2vec2-base-960h

```



> [!NOTE]

> The motion generation model with wav2vec2 encoder will be supported later.



### 3. Download LivePortraits checkpoints



```bash

# !pip install -U "huggingface_hub[cli]"

huggingface-cli download KwaiVGI/LivePortrait --local-dir pretrained_weights --exclude "*.git*" "README.md" "docs"

```



Refering to [Liveportrait](https://github.com/KwaiVGI/LivePortrait/tree/main) for more download methods.
