class TedliumDataset : public mindspore::dataset::Dataset

A source dataset for reading and parsing tedlium dataset.

Public Functions

TedliumDataset(const std::vector<char> &dataset_dir, const std::vector<char> &release, const std::vector<char> &usage, const std::vector<char> &extensions, const std::shared_ptr<Sampler> &sampler, const std::shared_ptr<DatasetCache> &cache)

Constructor of TedliumDataset.

Parameters

  • dataset_dir – [in] Path to the root directory that contains the dataset.

  • release – [in] Release of the dataset, can be “release1”, “release2”, “release3”.

  • usage – [in] Part of dataset of TEDLIUM, for release3, only can be “all”, for release1 and release2, can be “train”, “test” or “all”.

  • extensions – [in] The extensions of audio file. Only support “.sph” now.

  • sampler – [in] Shared pointer to a sampler object used to choose samples from the dataset. If sampler is not given, a RandomSampler will be used to randomly iterate the entire dataset.

  • cache – [in] Tensor cache to use.
