+# Speaker Verification with ResNet embeddings on Voxceleb
+
+This repository provides all the necessary tools to perform speaker verification with a pretrained ResNet 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 model performance on Voxceleb1-test set(Cleaned) is:
+
+| Release | EER(%) | minDCF |

+| 29-07-23 | 1.05 | 0.1082 | 
+
+
+## Pipeline description
+
+This system is composed of an ResNet TDNN model. 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 speechbrain
+```
+
+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 EncoderClassifier
+classifier = EncoderClassifier.from_hparams(source="speechbrain/spkrec-resnet-voxceleb")
+signal, fs =torchaudio.load('samples/audio_samples/example1.wav')
+embeddings = classifier.encode_batch(signal)
+```
+
+### Perform Speaker Verification
+
+```python
+from speechbrain.pretrained import SpeakerRecognition
+verification = SpeakerRecognition.from_hparams(source="speechbrain/spkrec-resnet-voxceleb", savedir="pretrained_models/spkrec-resnet-voxceleb")
+score, prediction = verification.verify_files("speechbrain/spkrec-resnet-voxceleb/example1.wav", "speechbrain/spkrec-resnet-voxceleb/example2.flac")
+```
+ The prediction is 1 if the two signals in input are from the same speaker and 0 otherwise.
+
+### Inference on GPU
+To perform inference on the GPU, add  `run_opts={"device":"cuda"}`  when calling the `from_hparams` method.
+
+### Training
+The model was trained with SpeechBrain (aa018540).
+To train it from scratch follows these steps:
+1. Clone SpeechBrain:
+```bash
+git clone https://github.com/speechbrain/speechbrain/
+```
+2. Install it:
+```
+cd speechbrain
+pip install -r requirements.txt
+pip install -e .
+```
+
+3. Run Training:
+```
+cd  recipes/VoxCeleb/SpeakerRec
+python train_speaker_embeddings.py hparams/train_resnet.yaml --data_folder=your_data_folder
+```
+
+You can find our training results (models, logs, etc) [here](https://drive.google.com/drive/folders/1-ahC1xeyPinAHp2oAohL-02smNWO41Cc?usp=sharing).
+
+### Limitations
+The SpeechBrain team does not provide any warranty on the performance achieved by this model when used on other datasets.
