Dataset Card for LibriSpeech-PC

Dataset Summary

LibriSpeech-PC is a parquet-backed merge of openslr/librispeech_asr audio metadata with SLR145 punctuation/capitalization manifests. It preserves the original LibriSpeech config/split layout (clean, other, all) and adds punctuation/casing targets.

Dataset Structure

Data Fields

file: path to the original LibriSpeech audio file.
audio: Audio feature with 16kHz sampling rate.
text: punctuated + cased transcript from LibriSpeech-PC manifests.
text_raw: raw transcript from LibriSpeech-PC manifests.
text_normalized: original normalized LibriSpeech ASR transcript.
speaker_id: speaker identifier.
chapter_id: chapter identifier.
id: utterance identifier.

Data Splits

Split names and configs mirror openslr/librispeech_asr. Some rows may be absent because the SLR145 manifests drop samples during punctuation/capitalization restoration.
