It is derived from open-source audio books from the LibriVox project. It contains over 60K hours of audio, which is, to our knowledge, the largest freely-available corpus of speech. The audio has been segmented using voice activity detection and is tagged with SNR, speaker ID and genre descriptions. Additionally, we provide baseline systems and evaluation metrics working under three settings: (1) the zero resource/unsupervised setting (ABX), (2) the semi-supervised setting (PER, CER) and (3) the distant supervision setting (WER). Settings (2) and (3) use limited textual resources (10 minutes to 10 hours) aligned with the speech. Setting (3) uses large amounts of unaligned text. They are evaluated on the standard LibriSpeech dev and test sets for comparison with the supervised state-of-the-art.","url_abs":"https://arxiv.org/abs/1912.07875v1","url_pdf":"https://arxiv.org/pdf/1912.07875v1.pdf","source":{"archive":"pwc-archive (Hugging Face), CC BY-SA 4.0","snapshot":"2025-07-28","licence_url":"https://creativecommons.org/licenses/by-sa/4.0/legalcode","row_kind":"abstracts"},"code_links":[{"paper_slug":"libri-light-a-benchmark-for-asr-with-limited","repo_url":"https://github.com/facebookresearch/libri-light","is_official":1,"mentioned_in_paper":1,"mentioned_in_github":1,"framework":"pytorch","reach":{"status":"ok","spdx":"MIT"}},{"paper_slug":"libri-light-a-benchmark-for-asr-with-limited","repo_url":"https://github.com/k2-fsa/libriheavy","is_official":0,"mentioned_in_paper":0,"mentioned_in_github":1,"framework":"none","reach":null}],"tasks":[{"task_slug":"speech-recognition","task_name":"Speech Recognition"},{"task_slug":"speech-recognition-1","task_name":"speech-recognition"}],"methods":[{"method_slug":"test","method_name":"Test"}],"datasets_introduced":[{"slug":"libri-light","name":"Libri-Light","full_name":""}],"methods_introduced":[],"results":[{"leaderboard":"/sota/speech-recognition-on-libri-light-test-clean","task":"Speech Recognition","dataset":"Libri-Light test-clean","model":"TDS 60k pseudo-label + CTC fine-tuning + 4gram-LM","rank_in_archive_order":2,"of":5,"metrics":{"Word Error Rate (WER)":"29.3"},"uses_additional_data":false},{"leaderboard":"/sota/speech-recognition-on-libri-light-test-clean","task":"Speech Recognition","dataset":"Libri-Light test-clean","model":"CPC unlab-60k+train-10h CPC pretrain + CTC fine-tuning + 4gram-LM","rank_in_archive_order":3,"of":5,"metrics":{"Word Error Rate (WER)":"43.9"},"uses_additional_data":false},{"leaderboard":"/sota/speech-recognition-on-libri-light-test-clean","task":"Speech Recognition","dataset":"Libri-Light test-clean","model":"CPC unlab-60k","rank_in_archive_order":4,"of":5,"metrics":{"ABX-across":"7.56","ABX-within":"5.83"},"uses_additional_data":false},{"leaderboard":"/sota/speech-recognition-on-libri-light-test-other","task":"Speech Recognition","dataset":"Libri-Light test-other","model":"TDS 60k pseudo-label + CTC fine-tuning + 4gram-LM","rank_in_archive_order":2,"of":5,"metrics":{"Word Error Rate (WER)":"56.6"},"uses_additional_data":false},{"leaderboard":"/sota/speech-recognition-on-libri-light-test-other","task":"Speech Recognition","dataset":"Libri-Light test-other","model":"CPC unlab-60k+train-10h CPC pretrain + CTC fine-tuning + 4gram-LM","rank_in_archive_order":3,"of":5,"metrics":{"Word Error Rate (WER)":"69.5"},"uses_additional_data":false},{"leaderboard":"/sota/speech-recognition-on-libri-light-test-other","task":"Speech Recognition","dataset":"Libri-Light test-other","model":"CPC unlab-60k","rank_in_archive_order":4,"of":5,"metrics":{"ABX-across":"13.42","ABX-within":"8.14"},"uses_additional_data":false}],"syntology":{"syntology_url":"https://syntology.ai/paper/1912.07875","atlas_url":"https://app.syntology.ai/?focus=1912.07875","mcp":{"get_harvested_code_for_paper":{"arxiv_id":"1912.07875"}},"developers":"https://syntology.ai/developers","read_at":"2026-09-25T09:33:49+00:00","read_at_is":"when the build read Syntology's graph, not when any sample ran","claim":"Per-sample execution status on synthesized fixtures; not a correctness claim about the paper.
