 This model is a fine-tuned version of [openai/whisper-medium](https://huggingface.co/openai/whisper-medium) on the IWSLT-2023, FLEURS, BiteSize, SpokenWords, Tatoeba, and Wikimedia, augmented with noise dataset.
-It achieves the following results on the evaluation set:
-- Loss: 1.1903
-- Bleu: 32.01
-- Chrf: 50.38
-- Wer: 62.7645
+The datasets are augmented in two ways: noise augmentation, and truncating low-magnitude samples. 
+The best model checkpoint (this version) based on ChrF is at step 2900, epoch 0.6349, 
+and it achieves the following results on the evaluation set:
+- Loss: 1.1883
+- Bleu: 32.88
+- Chrf: 51.52
