+# LibriVox public-domain chapter transcripts
+
+Machine-made transcripts with segment timestamps for 9 short LibriVox chapters (about 80 minutes of audio, about 14,100 words).
+
+## Files
+- `librivox_transcripts.jsonl`: one row per chapter, with `segments` as a list of `{start, end, text}` (seconds).
+- `librivox_transcripts.csv`: same rows; `segments_json` holds the segments as a JSON string.
+
+Columns: `title`, `author`, `chapter`, `source_url` (direct archive.org audio file), `archive_item` (archive.org page), `duration_seconds`, `language`, `word_count`, `transcript`, `segments`.
+
+## Source
+Audio: LibriVox volunteer recordings hosted on archive.org. LibriVox recordings are dedicated to the public domain, and the books read are public domain. Items:
+- https://archive.org/details/adventures_pinocchio_librivox (chapters 1-4)

+## License
+Audio: public domain (LibriVox). Transcripts and timestamps in this dataset: CC0 1.0.
+
+## Method
+Each file was fetched from archive.org and transcribed with the Apify actor [audio-transcriber](https://apify.com/pennydata/audio-transcriber) (language `en`, segments on). The text is raw machine output: it was not proofread, so expect errors in names, punctuation and rare words, and compare it with the printed book before using it as ground truth.
+
+I built the actor and earn from its runs. Transcripts were generated with AI (speech recognition) and the dataset was assembled with AI assistance (Claude).
