| # en cleaned speech corpus |
|
|
| This refresh provides a converged full train manifest, a frozen eval manifest, |
| and a token-coverage subset of approximately 5000 hours. |
| The validated FLAC payloads are reused without decoding or transcoding. Completely referenced Parquet shards are hard-linked locally; partial shards are filtered into exact row-only Parquet files. |
|
|
| ## Corpus overview |
|
|
| | Variant | Rows | Hours | |
| |---|---:|---:| |
| | train | 10,486,951 | 49951.119 | |
| | coverage_5000h | 972,368 | 4999.858 | |
| | eval | 544 | 1.999 | |
| |
| All audio locators are portable and have the form |
| `audio/<subset>/<group>/part-N.parquet#row=N`. |
| |
| The release audit records exact input/output hashes, rejected audio mappings, |
| language-tag validation, and zero train/eval audio-identity overlap. |
| |
| ```python |
| from datasets import load_dataset |
| ds = load_dataset("YuKuanFu/en", "en-5000h", split="train") |
| ``` |
| |
| ## Packaging exclusions |
| |
| Rows that could not be represented by the validated FLAC pool are omitted |
| and recorded here rather than silently replaced: |
| |
| | Variant | Rows | Hours | Reasons | |
