This is a repository for AMUSE: Emotional Speech-driven 3D Body Animation via Disentangled Latent Diffusion. AMUSE generates realistic emotional 3D body gestures directly from a speech sequence (top). It provides user control over the generated emotion by combining the driving speech with a different emotional audio (bottom).

News 🚩

• [2024/06/12] Code is available.
• [2024/02/27] AMUSE has been accepted for CVPR 2024! Working on code release.
• [2023/12/08] ArXiv is available.

Tasks

Once the above setup is correctly done, you can execute the following:

• train_audio (training step 1/2)
  Train AMUSE step 1 of the speech disentanglement model.

  cd $AMUSEPATH/scripts
  python main.py --fn train_audio

• train_gesture (training step 2/2)
  Train AMUSE step 2 of the gesture generation model.

  cd $AMUSEPATH/scripts
  python main.py --fn train_gesture

• infer_gesture
  Infer AMUSE on a single 10s WAV monologue audio sequence.
  Place audio in $AMUSEPATH/viz_dump/test/speech.
  Video of generated gesture will be in $AMUSEPATH/viz_dump/test/gesture.

  cd $AMUSEPATH/scripts
  python main.py --fn infer_gesture

• edit_gesture
  COMING SOON

  cd $AMUSEPATH/scripts
  python main.py --fn infer_gesture

• bvh2smplx_
  Convert BVH to SMPLX (only with provided BMAP presets from AMUSE website download page if possible).
  Highly experimental, no support. Place BVH file inside $AMUSEPATH/data/beat-rawdata-eng/beat_rawdata_english/<<actor_id>>, where actor_id is between 1 and 30. The converted file will be in $AMUSEPATH/viz_dump/smplx_conversions.

  cd $AMUSEPATH/scripts
  python main.py --fn bvh2smplx_

  Once converted, import the file in Blender using the SMPLX blender addon. Remember to specify the target FPS (for current file: 24 FPS) in the import animation window while importing the NPZ file.

• prepare_data
  Train AMUSE on BEAT 0.2.1 or BEAT-X or custom dataset. COMING SOON: Conversion script, dataloader LMDB file creation.

  cd $AMUSEPATH/scripts
  python main.py --fn prepare_data

• other
  COMING SOON
