This repository is the official PyTorch implementation of our paper: Emotionally Enhanced Talking Face Generation accepted at ACM MM 2023, McGE Workshop and ICCV 2023, CVEU Workshop. We introduce a multimodal framework to generate lipsynced videos agnostic to any arbitrary identity, language, and emotion. Our proposed framework is equipped with a user-friendly web interface with a real-time experience for talking face generation with emotions.

All results from this open-source code or our demo website should only be used for research/academic/personal purposes only.
- ffmpeg:
sudo apt-get install ffmpeg - Install necessary packages using
pip install -r requirements.txt. - Face detection pre-trained model should be downloaded to
face_detection/detection/sfd/s3fd.pth. Alternative link if the above does not work.
Download the data from this repo.

Note: For simplification in the code, we have used torch.utils.data.random_split in the training scripts to split the CREMA-D dataset into training and testing sets. There is no official train-test split of CREMA-D. Ideally, you should follow this evaluation protocol for splitting.
Comment these code lines for inference: line1 and line2.
python inference.py --checkpoint_path <ckpt> --face <video.mp4> --audio <an-audio-source> --emotion <categorical emotion>The result is saved (by default) in results/{emotion}.mp4. You can specify it as an argument, similar to several other available options. The audio source can be any file supported by FFMPEG containing audio data: *.wav, *.mp3, or even a video file, from which the code will automatically extract the audio. Choose categorical emotion from this list: [HAP, SAD, FEA, ANG, DIS, NEU].
- Experiment with the
--padsargument to adjust the detected face bounding box. Often leads to improved results. You might need to increase the bottom padding to include the chin region. E.g.,--pads 0 20 0 0. - If you see the mouth position dislocated or some weird artifacts such as two mouths, then it can be because of over-smoothing the face detections. Use the
--nosmoothargument and give it another try. - Experiment with the
--resize_factorargument, to get a lower-resolution video. Why? The models are trained on faces that were at a lower resolution. You might get better, visually pleasing results for 720p videos than for 1080p videos (in many cases, the latter works well too).
Please check the evaluation/ folder for the instructions.
- Train the model on MEAD dataset.
- Develop a metric to evaluate the video quality in case of emotion incorporation.
- Improve the demo website based on the user study in the paper.
