Whisper Medium GA-EN Speech Translation
This model is a fine-tuned version of openai/whisper-medium on the IWSLT-2023, FLEURS, BiteSize, SpokenWords, Tatoeba, and Wikimedia, augmented with noise dataset. The datasets are augmented in two ways: noise augmentation, and truncating low-amplitude 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
- Wer: 62.0441
