 ## Original Dataset
 
 The original RAVDESS dataset is available at: https://zenodo.org/records/1188976
 
 The Ryerson Audio-Visual Database of Emotional Speech and Song (RAVDESS) contains 7356 files (total size: 24.8 GB). The dataset contains 24 professional actors (12 female, 12 male), vocalizing two lexically-matched statements in a neutral North American accent.

 ## Preprocessing Details
 
 We have performed normalization preprocessing on the speech portion of the RAVDESS dataset for use in our cross-modal knowledge distillation work. The preprocessing focuses exclusively on the speech content (vocal channel 01) and does not include song data (vocal channel 02). The preprocessing consists of three main steps:
