Open the original- What it measures
- Table 3 of the paper gives word error rate for each English test set. The paper calls the Voxtral results macro-averages in its figures, and this row is one test set.
- 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.
