Speech Emotion Recognition By Fine-Tuning Wav2Vec 2.0
The model is a fine-tuned version of jonatasgrosman/wav2vec2-large-xlsr-53-english for a Speech Emotion Recognition (SER) task.
Several datasets were used the fine-tune the original model:
- Surrey Audio-Visual Expressed Emotion (SAVEE) (http://kahlan.eps.surrey.ac.uk/savee/Database.html) - 480 audio files from 4 male actors
- Ryerson Audio-Visual Database of Emotional Speech and Song (RAVDESS) (https://zenodo.org/record/1188976) - 1440 audio files from 24 professional actors (12 female, 12 male)
- Toronto emotional speech set (TESS) (https://tspace.library.utoronto.ca/handle/1807/24487) - 2800 audio files from 2 female actors
7 labels/emotions were used as classification labels
emotions = ['angry' 'disgust' 'fear' 'happy' 'neutral' 'sad' 'surprise']
It achieves the following results on the evaluation set:
- Loss: 0.104075
- Accuracy: 0.97463
