LibriSpeech [Panayotov et al., 2015] dataset.

Parameters:
  • root (str or Path) – Path to the directory where the dataset is found or downloaded.

  • url (str, optional) – The URL to download the dataset from, or the type of the dataset to dowload. Allowed type values are "dev-clean", "dev-other", "test-clean", "test-other", "train-clean-100", "train-clean-360" and "train-other-500". (default: "train-clean-100")

  • folder_in_archive (str, optional) – The top-level directory of the dataset. (default: "LibriSpeech")

  • download (bool, optional) – Whether to download the dataset if it is not found at root path. (default: False).
