PyTorch Datasets

Caution

Lhotse datasets are still very much in the works and are subject to breaking changes.

We supply subclasses of the torch.data.Dataset for various audio/speech tasks. These datasets are created from CutSet objects and load the features from disk into memory on-the-fly. Each dataset accepts an optional root_dir argument which is used as a prefix for the paths to features and audio.

Currently, we provide the following:
