Audio captioning DCASE 2020 evaluation (testing) split

  • 1. Audio Research Group, Faculty of Information Technology and Communication Sciences, Tampere University


This is the evaluation split for Task 6, Automated Audio Captioning, in DCASE 2020 Challenge

This evaluation split is the Clotho testing split, which is thoroughly described in the corresponding paper: 

K. Drossos, S. Lipping and T. Virtanen, "Clotho: an Audio Captioning Dataset," IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), Barcelona, Spain, 2020, pp. 736-740, doi: 10.1109/ICASSP40776.2020.9052990.

This evaluation split is meant to be used for the purposes of the Task 6 at the scientific challenge DCASE 2020. This split it is not meant to be used for developing audio captioning methods. For developing audio captioning methods, you should use the development and evaluation splits of Clotho. 

If you want the development and evaluation splits of Clotho dataset, you can find them also in Zenodo, at:
