• 10-Scale Semantic Relevancy: BEAT provides a score and category-label for semantic relevancy between gestures and speech content: no gestures (0), beat gestures (1), low-middle-high quaility deictic gestures (2,3,4), iconic gestures (5,6,7), metaphoric gestures (8,9,10).
• 8-Class Emotional Gestures: For each speaker, data in speech section are recorded with eight emotions: neutral, happiness, anger, sadness, contempt, surprise, fear, and disgust. Data in conversation are labeled as neutral.
• 4-Modality Captured Data: With 16 cameras motion capture system and iphone arkit, BEAT recorded data in four modalities: 75 joints' motion, 52 dimensions blendshape weights, audio and text.
• 76-Hour and 30-Speaker: BEAT (English data) consists of 10 recorded four hours speakers and 20 recorded one hour speakers.
• 4-Language: BEAT contains four types of languages: English (60h), Chinese (12h), Spanish (2h) and Japanese (2h). For the latter three languages, speakers also record English data to provide paired data.
• 2-Scenario: BEAT provides speech (50%) and conversation (50%) recording.

*Checkpoints results trained from this repo. are denoted in parentheses. Results in paper are from codes: seq2seq, s2g, a2g, mutli, camn.

**Pretrained 300D AutoEncoder for FID calculation.

0. python == 3.7
1. build folders like:

   audio2pose
   ├── codes
   │   └── audio2pose
   ├── datasets
   │   ├── beat_raw_data
   │   ├── beat_annotations
   │   └── beat_cache
   └── outputs
       └── audio2pose
           ├── custom
           └── wandb   
   

2. download the scripts to codes/audio2pose/
3. run pip install -r requirements.txt in the path ./codes/audio2pose/
4. download full dataset to datasets/beat
5. bulid data cache and calculate mean and std by given number of joints, FPS, speakers using /dataloader/preprocessing.ipynb
6. cd ./dataloaders && python build_vocab.py for language model
7. run python train.py -c ./configs/ae_4english_15_141.yaml for pretrained_ae for FID calculation, or download pretrained ckpt to /datasets/beat_cache/cache_name/weights/
8. run python train.py -c ./configs/camn_4english_15_141.yaml for training or or download pretrained ckpt to /datasets/beat_cache/cache_name/weights/.
9. run python test.py -c ./configs/camn_4english_15_141.yaml for inference.
10. load ./outputs/audio2pose/custom/exp_name/epoch_number/xxx.bvh into blender to visualize the test results.

• refer train and test CaMN for bvh cache
• remove modalities, e.g., remove facial expressions.
  • set facial_rep: None and facial_f: 0 in .yaml
  • set dataset: trinity in .yaml
