LibriSpeech clean (Lance Format) is a Lance-formatted version of the LibriSpeech ASR clean configuration. Audio is stored inline as FLAC bytes (no re-encoding); transcripts are sentence-embedded for out-of-the-box semantic transcript search. The dataset includes standard ASR validation and test sets, and a 100-hour clean training subset. The schema comprises audio, sampling rate, transcript text, speaker ID, chapter ID, character count, and text embedding. Pre-built vector and full-text indices enable efficient searching. The dataset is sourced from openslr/librispeech_asr, built from the public-domain LibriVox audiobook corpus, and released under CC BY 4.0 license.
