# Xvector embeddings extraction on Voxceleb

This repository provides all the necessary tools to extract speaker embeddings with a pretrained TDNN model with SpeechBrain. 
The system is trained on Voxceleb 1+ Voxceleb2 training data. 

This repo traces the model shared at: https://huggingface.co/speechbrain/spkrec-xvect-voxceleb

For using this model, SpeechBrain is not required.

To use the model:

```python
import torchaudio
import torch

device = "cpu"  # or "cuda" for loading the model to a GPU 
model = torch.jit.load(f"<this_repo>/model_{device}.pt")
wavsignal, fs = torchaudio.load('audio.wav')
embeddings = model(wavsignal).squeeze()
```

## Warning

This model can only forward 1 wave audio.
Also, this model was traced for speaker embedding extraction, 
so any additional task (Speaker Classification, Verification) is disabled.

You can retrace the model using the code shared at: "tracing_code.py"

### Limitations
The SpeechBrain team does not provide any warranty on the performance achieved by this model when used on other datasets.
