nan_new — cleaned Taiwanese Hokkien ASR corpus

This release contains a cleaned full training set and a frozen evaluation set. Audio is embedded in Parquet and can be streamed directly by the Hugging Face datasets library.

Splits

  • train: 3,209,619 rows, 10475.161 hours
  • eval: 709 rows, 1.976 hours

The train split contains 3,209,619 cleaned base rows. No external code-switch corpus is included in this release. The frozen eval audio is physically separated from train. Audio-ID and audio-locator overlap between train and eval are both zero.

Exact transcript strings may occur in both splits when they belong to distinct recordings; common short utterances are not treated as sample leakage.

See release.json for input hashes, cleaning counts, shard checksums, and the base Hub revision used to build this release.
