LRLspoof

Multilingual low-resource-language anti-spoofing benchmark: 1,304,455 TTS (spoof) utterances across 66 languages and many TTS systems. Spoof-only (no bonafide).

The audio ships as the multi-part tarball lrl_spoof.tar.gz.part_*; download + extract it into a <language>/<tts_model>/<file>.wav tree. load_dataset is not the access path here (the dataset is the tarball). data/labels.parquet (utterance_id + label, all spoof) exists only for arena re-verification.

Arena scoring

Scored on 1-SRR (srr_complement, lower is better) at a fixed threshold t* calibrated on DeepVoice. A submission must include a calibration block with the DeepVoice operating-point threshold.

utterance_id convention

utterance_id = the audio file path relative to the dataset root, e.g. english/fastpitch/line_59.wav. A submitter's scores.txt keys by this id; emit <utterance_id> <score> with higher score = more bonafide.
