# Speaker Verification with ECAPA-TDNN embeddings on Voxceleb

This repository provides all the necessary tools to perform speaker verification with a pretrained ECAPA-TDNN model using SpeechBrain. 
The system can be used to extract speaker embeddings as well. 
It is trained on Voxceleb 1+ Voxceleb2 training data. 

For a better experience, we encourage you to learn more about
[SpeechBrain](https://speechbrain.github.io). The given ASR model performance on Voxceleb1-test set are:

## Pipeline description

This ASR system is composed of an ECAPA-TDNN model. It is a combination of convolutional and residual blocks. The embeddings are extracted using attentive statistical pooling. The system is trained with Additive Margin Softmax Loss.  Speaker Verification is performed using cosine distance between speaker embeddings.

## Install SpeechBrain

First of all, please install SpeechBrain with the following command:

```
pip install \\we hide ! SpeechBrain is still private :p
```

Please notice that we encourage you to read our tutorials and learn more about
[SpeechBrain](https://speechbrain.github.io).

### Compute your speaker embeddings

```python
import torchaudio
from speechbrain.pretrained import SpeakerRecognition
verification = SpeakerRecognition.from_hparams(source="speechbrain/spkrec-ecapa-voxceleb")
signal, fs =torchaudio.load('samples/audio_samples/example1.wav')
embeddings = verification.encode(signal)
```

### Perform Speaker Verification

```python
import torchaudio
from speechbrain.pretrained import SpeakerRecognition
verification = SpeakerRecognition.from_hparams(source="speechbrain/spkrec-ecapa-voxceleb")
signal, fs =torchaudio.load('samples/audio_samples/example1.wav')
signal2, fs = torchaudio.load('samples/audio_samples/example2.flac')
score, prediction = verification.verify(signal, signal2)
```
 The prediction is 1 if the two signals in input are from the same speaker and 0 otherwise.
