Open the original- What it measures
- The model card's multilingual table uses a Transducer decoder with greedy decoding and no external language model. Punctuation and capitalization are removed from the reference and predicted text before scoring.
- What it does not show
- NVIDIA's own run, scored without punctuation or capitalization, so it is not a full-transcript score. The card notes that Portuguese scores may reflect a mismatch between European Portuguese training data and Brazilian Portuguese benchmarks.
