samromur-21.05 (test splits only)

Author: Páll Rúnarsson, Reykjavík University
HUMI Laboratory – Language and Voice Laboratory

Evaluation-only release accompanying "Scaling Smaller ASR Models Against Multilingual ASR Giants" (ICASSP 2027). Contains only the test-related splits of palli23/samromur-21.05 -- the training pool is not redistributed here.

test: the official test split (10000 utt., 15.9h, 34% OOV against the paper's independently-trained 21.05 scaling set).
InVocabTest: vocabulary-controlled subset (4211 utt.) whose every word already appears in the 21.05 training vocabulary -- isolates error due to genuinely novel vocabulary.
