title: Clotho dataset

description: <strong>=== There is a newer version. Please use the newer version ===</strong> Clotho is an audio captioning dataset, now reached version 2. Clotho consists of 6974 audio samples, and each audio sample has five captions (a total of 34 870 captions). Audio samples are of 15 to 30 s duration and captions are eight to 20 words long. Clotho is thoroughly described in our paper: <em>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.</em> available online at: https://arxiv.org/abs/1910.09387 and at: https://ieeexplore.ieee.org/document/9052990 <strong>If you use Clotho, please cite our paper.</strong> <strong>To use the dataset, you can use our code at:</strong> https://github.com/audio-captioning/clotho-dataset These are the files for the development, validation, and evaluation splits of Clotho dataset. -------------------------------------------------------------------------------------------------------- <strong>== Changes in version 2 ==</strong> In version 2 of Clotho, there are audio files added in the development split and a new validation split is added. There are no changes in the evaluation split. Specifically: Now there are 3840 audio files in the development split. In Clotho version 1, there were 2893 audio files. Now, 947 new audio files are added. There are 1046 new audio files in the validation split. All new captions are treated as in version 1 of Clotho, i.e. having word consistency, no named entities, no speech transcription, and no hapax legomena between splits (i.e. words appearing only in one of the splits). -------------------------------------------------------------------------------------------------------- <strong>== Usage ==</strong> To use the dataset you have to: Download the audio files: clotho_audio_development.7z,clotho_audio_validation.7z, and clotho_audio_evalution.7z Download the files with the captions: clotho_captions_development.csv, clotho_captions_validation.csv, and clotho_captions_evaluation.csv Download the files with the associated metadata: clotho_metadata_development.csv, clotho_metadata_validation.csv, and clotho_metadata_evaluation.csv Extract the audio files Then you can use each audio file with its corresponding captions -------------------------------------------------------------------------------------------------------- <strong>== License ==</strong> The audio files in the archives: clotho_audio_development.7z, clotho_audio_validation.7z, and clotho_audio_evalution.7z and the associated meta-data in the CSV files: clotho_metadata_development.csv clotho_metadata_validation.csv clotho_metadata_evaluation.csv are under the corresponding licences (<strong><em>mostly CreativeCommons with attribution</em></strong>) of Freesound [1] platform, mentioned explicitly in the CSV files for each of the audio files. That is, each audio file in the 7z archives is listed in the CSV files with the meta-data. The meta-data for each file are: File name Keywords URL for the original audio file Start and ending samples for the excerpt that is used in the Clotho dataset Uploader/user in the Freesound platform (manufacturer) Link to the licence of the file The captions in the files: clotho_captions_development.csv clotho_captions_validation.csv clotho_captions_evaluation.csv are under the Tampere University licence, described in the LICENCE file (<strong><em>mainly a non-commercial with attribution licence</em></strong>). -------------------------------------------------------------------------------------------------------- <strong>== References ==</strong><br> [1] Frederic Font, Gerard Roma, and Xavier Serra. 2013.
