-The ASR performance is measured with word error rate (WER) on [MCV-16.1](https://commonvoice.mozilla.org/en/datasets) test sets on four languages, and we process the groundtruth and predicted text with [whisper-normalizer](https://pypi.org/project/whisper-normalizer/).

 ### AST Performance
 
-We evaluate AST performance with BLEU score on the [FLEURS](https://huggingface.co/datasets/google/fleurs) test sets on four languages and use their native annotations with punctuation and capitalization.
