Indonesian Speech Emotion Recognition By Fine-Tuning Wav2Vec 2.0

The model is a fine-tuned version of facebook/wav2vec2-base for a Speech Emotion Recognition (SER) task.

The dataset used to fine-tune the original pre-trained model is the RAVDESS dataset. This dataset provides 1440 samples of recordings from actors performing on 5 different emotions in Bahasa Indonesia, which are:

emotions = ['angry', 'disgust', 'fear', 'happy', 'sad']

It achieves the following results on the evaluation set:

Loss: 0.5023
Accuracy: 0.8223
