End-to-End Spectro-Temporal Graph Attention Networks for Speaker Verification Anti-Spoofing and Speech Deepfake Detection
===============
This repository contains our implementation of the paper published in the ASVspoof 2021 workshop, "End-to-End Spectro-Temporal Graph Attention Networks for Speaker Verification Anti-Spoofing and Speech Deepfake Detection". This work demonstrates the effectivness of end-to-end spectro-temporal graph attention network (GAT) which learns the relationship between cues spanning different sub-bands and temporal intervals for anti-spoofing and speech deepfake detection.

## Installation
First, clone the repository locally, create and activate a conda environment, and install the requirements :
```
$ git clone https://github.com/eurecom-asp/RawGAT-ST-antispoofing.git
$ conda create --name RawGAT_ST_anti_spoofing python=3.8.8
$ conda activate RawGAT_ST_anti_spoofing
$ conda install pytorch torchvision torchaudio cudatoolkit=11.1 -c pytorch -c nvidia
$ pip install -r requirements.txt
```

## Experiments

### Dataset
Our experiments are done in the logical access (LA) partition of the ASVspoof 2019 dataset, which can can be downloaded from [here](https://datashare.is.ed.ac.uk/handle/10283/3336).

### Training
To train the model run:
```
python main.py --track=logical --loss=WCE   --lr=0.0001 --batch_size=10
```

### Testing

To evaluate your own model on LA evaluation dataset:

```
python main.py --track=logical --loss=WCE --is_eval --eval --model_path='/path/to/your/best_model.pth' --eval_output='eval_CM_scores_file.txt'
```

We also provide a pre-trained models. To use it you can run: 
```
python main.py --track=logical --loss=WCE --is_eval --eval --model_path='Pre_trained_models/RawGAT_ST_mul/Best_epoch.pth' --eval_output='RawGAT_ST_mul_LA_eval_CM_scores.txt'
```

If you would like to compute scores on development dataset simply run:

```
python main.py --track=logical --loss=WCE --eval --model_path='/path/to/your/best_model.pth' --eval_output='dev_CM_scores_file.txt'
```
Compute the min t-DCF and EER(%) on development dataset
```
python tDCF_python_v2/evaluate_tDCF_asvspoof19_eval_LA.py  dev  'dev_CM_scores_file.txt'
```

Compute the min t-DCF and EER(%) on evaluation dataset
```
python tDCF_python_v2/evaluate_tDCF_asvspoof19_eval_LA.py  Eval  'eval_CM_scores_file.txt'
```
