CNN14 Trained on VGGSound dataset with SimCLR and Fine Tuned on ESC50

This repository provides all the necessary tools to perform audip classification with CNN14 model model, implemented with SpeechBrain. For a better experience we encourage you to learn more about SpeechBrain. The encoder is first trained with SimCLR on the VGGSound dataset, and then fine tuned on ESC50 folds 1,2,3.

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.

Perform Classification on your own file

from speechbrain.inference.classifiers import AudioClassifier 

model = AudioClassifier.from_hparams(source="speechbrain/cnn14-esc50", savedir='pretrained_models/cnn14-esc50')
out_probs, score, index, text_lab = model.classify_file('speechbrain/cnn14-esc50/example_dogbark.wav')

print(text_lab)

Limitations

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