IRIS-Data

IRIS (Instruction-Aware Retrieval for Speech) is a dataset for training instruction-aware speech retrieval models. Each example contains an instruction, a spoken query, a positive document, negative documents, and metadata describing the retrieval criteria.

Files

File	Contents
`train.jsonl`	890,278 training examples.
`val.jsonl`	9,653 validation examples.
`audio/audio-*.tar`	391,468 WAV recordings, packaged in shards for download.

Extracting the audio archives creates audio/<id>.wav, matching the relative paths in both JSONL files. The WAV files are preserved without resampling or re-encoding.

Example format

Field	Description
`instruction`	The retrieval instruction.
`spoken_query`	Relative path to the query recording.
`positive_document`	Relative path to a positive recording.
`negative_documents`	List of relative paths to negative recordings.
`select_criteria`	The criteria used to select the positive and negative documents.
`spoken_query_metadata`	Metadata for the query.
`positive_document_metadata`	Metadata for the positive document.
`negative_documents_metadata`	Metadata for the negative documents.
`source`	The source dataset identifier.

Metadata fields include speaker, gender, emotion, accent, sentiment, environmental_sound, dialogue_id, topic_id, and text. Unavailable attributes are represented by null.

Download

After access is approved, download the files using an authenticated Hugging Face account:

hf download lca0503/IRIS-Data --repo-type dataset --local-dir IRISData

for archive in IRISData/audio/audio-*.tar; do
    tar -xf "$archive" -C IRISData
done

Resolve the audio paths relative to the downloaded IRISData directory.
