# sapa
### Code:
Below are the step to setup the code and perform training
### Setup:
After setting up the code as below, update the paths appropriately
> git clone https://github.com/ksasi/sapa.git
### Install Dependencies:
> cd sapa
>
> pip install -r requirements.txt
## Speaker Verification
### Datasets :
- Create and change directory to ***dataset*** under ***Speaker_Verification***
- Download [VoxCeleb1-H (small subset)] (https://iitjacin-my.sharepoint.com/:u:/g/personal/d22cs051_iitj_ac_in/EVhTqG7PeDFBlkgHrG7WSJoB63ievtSFmE-PLdSxHtSNqA?e=Nlf8fX)
- Download [Kathbath dataset] (https://github.com/AI4Bharat/IndicSUPERB)
Dataset **Kathbath** structure after extraction :
```
Audio Data
data
├── telugu
│ ├──
│ │ ├── 844483828886543-594-f.m4a
│ │ ├── 765429982765376-973-f.m4a
│ │ ├── ...
├── tamil
├── ...
Transcripts
data
├── telugu

```
Convert m4a to wav format as below :
> git clone https://github.com/AI4Bharat/IndicSUPERB.git
```
python utilities/structure.py \
/kb_data_clean_m4a \
/kb_data_clean_wav \
```
### Models Evaluation (VoxCeleb1-H (small subset)) :
Execute the below script to evaluate models (XLSR-Wav2Vec2, UniSpeech-SAT and WavLM-Base) with EER(%) using VoxCeleb1-H (small subset)
> cd Speaker_Verification
>
> nohup python eval_voxceleb.py > \/log/eval_log_voxceleb.out &
>
### Models Evaluation (Kathbath - Telugu) :
Execute the below script to evaluate models (XLSR-Wav2Vec2, UniSpeech-SAT and WavLM-Base) with EER(%) using test partition of Kathbath - Telugu dataset
> cd Speaker_Verification
>
> nohup python eval_kathbath.py > \/log/eval_log_kathbath.out &
>
### Fine-tune and evaluate WavLM model :
Execute the below script to fine-tune WavLM model on **valid partition** of Kathbath - Telugu dataset
> cd Speaker_Verification
>
> nohup python train_WavLM.py > \/log/WavLM_log_finetune.out &
>
Execute the below script to evaluate the fin-tuned WavLM mode on **test partition** of Kathbath - Telugu dataset
> cd Speaker_Verification
>
> nohup python eval_WavLM.py > \/log/WavLM_log_ft_eval.out &
>
## Source Separation
### Datasets :
- Setup LibriMix repo as below
> git clone https://github.com/JorisCos/LibriMix.git
>
> cd /LibriMix/metadata/Libri2Mix
Delete all folders , except **libri2mix_test-clean_info.csv** and **libri2mix_test-clean.csv**
- Execute the below script to generate LibriMix dataset
> cd /LibriMix
>
> ./generate_librimix.sh storage_dir
where storage_dir = /dataset
### Model(SepFormer) Evaluation (LibriMix - LibriSpeech test clean partition) :
Execute the below script to perform evaluation of SepFormer on test split of (70-30 of LibriMix - LibriSpeech test clean partition)
> cd Source_Separation
>
> nohup python eval_separator.py > \/log/eval_sepformer_librimix_batch_size8.out &
### Model(SepFormer) fine-tuning and Evaluation
Execute the below steps to fine-tune and evaluate SepFormer :
- Adopt the speechbrain [recipe](https://github.com/speechbrain/speechbrain/tree/develop/recipes/WSJ0Mix/separation) and fine-tune as below:
- Generate train and test csv files by executing `csv_generator.py` as below :
>
> cd Source_Separation
>
> python csv_generator.py
>
- Clone `speechbrain` repo and update `train.py` , `sepformer.yaml` as below:
>
> git clone https://github.com/speechbrain/speechbrain.git
>
> cp \/Source_Separation/train.py \/Source_Separation/speechbrain/recipes/WSJ0Mix/separation/train.py
>
> cp \/Source_Separation/sepformer.yaml \/Source_Separation/speechbrain/recipes/WSJ0Mix/separation/hparams/sepformer.yaml
>
- Fine-tune sepformer with LibriMix dataset by running `train.py` as below:
>
> cd \/Source_Separation
>
> nohup \/Source_Separation/speechbrain/recipes/WSJ0Mix/separation/train.py \/Source_Separation/speechbrain/recipes/WSJ0Mix/separation/hparams/sepformer.yaml > \/log/sepformer_ft.out &
### Demo (Speaker Verification) :
Demo of **Speaker Verification** from audio inputs can be executed by running `Speaker_Verification_Demo.ipynb` ipython notebook in the Demo folder
