Standalone ECAPA-TDNN embeddings with discrete_ssl input on Voxceleb
This repository provides all the necessary tools to obtain speaker embeddings with a pretrained ECAPA-TDNN model and discrete audio input using SpeechBrain. It is trained on Voxceleb 1 training data.
Adopted from poonehmousavi/discrete_wavlm_spk_rec_ecapatdn
For a better experience, we encourage you to learn more about SpeechBrain. The model performance on Voxceleb1-test set(Cleaned) is:
Pipeline description
This system is composed of an ECAPA-TDNN model and discrete_ssl 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 git+https://github.com/speechbrain/speechbrain.git@develop
Please notice that we encourage you to read our tutorials and learn more about SpeechBrain.
Compute your speaker embeddings
import torchaudio
from speechbrain.inference.interfaces import foreign_class
classifier = foreign_class(source="flexthink/discrete_wavlm_spk_rec_ecapatdn", pymodule_file="custom_interface.py", classname="DiscreteSpkEmb")
tokens = torch.randint(4, 100, 4)
embeddings = classifier.encode_batch(signal)
print(embeddings.shape)
The system is trained with recordings sampled at 16kHz (single channel). The code will automatically normalize your audio (i.e., resampling + mono channel selection) when calling classify_file if needed. Make sure your input tensor is compliant with the expected sampling rate if you use encode_batch and classify_batch.
Limitations
The SpeechBrain team does not provide any warranty on the performance achieved by this model when used on other datasets.
