Open the original (DOI 10.48550/arXiv.2212.04356)- What it measures
- FLEURS is the paper's multilingual read-speech benchmark. Its table gives each language's word error rate in a column, and the Whisper large-v2 row is the largest of the table's models.
- What it does not show
- Read speech on one test set per language, so it describes clean read speech, not conversation or noise. Word error rate depends on the paper's text normalization. Only the large-v2 row is written here.
