| Test set | CER | WER | Whisper-large-v3 (zero-shot) CER |
|---|---|---|---|
| FLEURS | 3.79 | 13.33 | 4.06 |
| Common Voice 25 | 0.36 | 1.44 | 4.29 |

The language/task prompt is baked into the generation config, so no language= argument is needed.
FLEURS + Common Voice Corpus 25.0 (Mozilla, March 2025; https://commonvoice.mozilla.org/en/datasets), capped per the paper. Text-only data from the Goldfish corpus (Chang et al., 2026).
Monolingual (Bulgarian only). Evaluated on FLEURS / Common Voice test splits; other domains or dialects may differ.
