Parameters

  • mode (str, optional) – It identifies the dataset mode (train or dev). Defaults to train.

  • n_folds (int, optional) – Split the dataset into n folds. 1 fold for dev dataset and n-1 for train dataset. Defaults to 5.

  • split (int, optional) – It specify the fold of dev dataset. Defaults to 1.

  • feat_type (str, optional) – It identifies the feature type that user wants to extract of an audio file. Defaults to raw.

  • archive (dict) – it tells where to download the audio archive. Defaults to None.

Returns

Dataset. An instance of TESS dataset.
