Open the original- What it measures
- FLEURS is a benchmark of read speech. The columns are Arabic (ar), Dutch (nl), English (en), French (fr), German (de), Hindi (hi), Italian (it), Portuguese (pt) and Spanish (es). The table sits in the same paper, so the systems were compared on the same test.
- What it does not show
- Vendor-run comparison on one read-speech test set. Results for conversational or noisy audio may differ.
