Checked against its source on October 17, 2026
- What it measures
- Both rates come from the same FLEURS test and the same large-v2 model in the Whisper paper, so the ratio compares the two languages on equal terms. It is a rounded ratio of two word error rates, not a separate measurement.
- How it is calculated
- 14.3 / 4.2 = 3.4
