This repository consists of models, scripts, and notebooks that help you to use all the benefits of Wav2Vec 2.0 in your research. In the following, I'll show you how to train speech tasks in your dataset and how to use the pretrained models.

How to train

I'm just at the beginning of all the possible speech tasks. To start, we continue the training script with the speech emotion recognition problem.

Output:
