LibriSpeech train-clean-460 ASR, Mel, and retrieval-event features
Public derived-feature release for the canonical LibriSpeech train-clean-100 and
train-clean-360 splits. It contains Whisper ASR word/timestamp JSON, schema-v2
retrieval-event metadata, and packed 80-bin log-Mel tensors. It contains no clinical
material, model weights, private paths, or source audio.
Layout
data/train-clean-100/anddata/train-clean-360/: WebDataset-style tar shards.manifests/train-clean-100.csvandmanifests/train-clean-360.csv: portable public recording manifests.provenance/dataset.json: source, exclusion, validation, and manifest hashes.provenance/shards.json: canonical record counts, byte counts, and SHA-256 checksums for every uploaded shard.
Each tar contains three members per recording: .asr.json, .events.json, and
.mel.safetensors. Absolute source/cache paths were removed and internal references were
rewritten to portable member names.
