# LibriSpeech ASR corpus: train-clean-100 and dev-clean (archive mirror)

This repository is a mirror for reproducible builds: the files are exact copies of the published originals listed below (byte for byte; `SHA256SUMS` gives the SHA-256 of each). Please cite and credit the original authors.

## Contents

Two archives of the LibriSpeech ASR corpus, unchanged, as published on OpenSLR (resource SLR12):

- `train-clean-100.tar.gz`: the train-clean-100 subset;
- `dev-clean.tar.gz`: the dev-clean subset.

Total: 6.73 GB. Check a download with `sha256sum -c SHA256SUMS`.
