AudioCC-Lab/PICSAFEv1

Speech Quality Test Labels

It publishes only this README and metadata.jsonl, because the 14 source datasets have different copyright and access terms.

The manifest contains the 10,728-sample PICSAFEv1 subset. It is not a license to redistribute the underlying recordings.

Metadata fields

• file_name: audio basename.
• id: globally unique sample identifier with the [source] prefix.
• source: source dataset name.
• source_path: path relative to the origin directory.
• tags: list of labels.
