Open the original- What it measures
- FLEURS is a multilingual benchmark of read speech. The table sits in the same paper, so the systems were compared on the same test.
- What it does not show
- One paper's runs under its own text normalization and decoding, so compare systems within this table, not with other papers' numbers. The paper gives no date per row.
