Whisper largeV2 Spanish MLS

This model is a fine-tuned version of openai/whisper-large-v2 on the facebook/multilingual_librispeech spanish dataset. It achieves the following results on the evaluation set:

Loss: 0.0910
Wer: 3.4678

Model description

The model is fine-tuned for 4000 updates/steps on multilingual librispeech Spanish train data.

Zero-shot - 4.2 (MLS Spanish test)
Fine-tune MLS spanish train - 3.46 (MLS Spanish test) (-17.61%)

Zero-shot - 6.3 (CV11 test)
Fine-tune MLS spanish train - 8.38 (CV11 test)

When the model is fine-tuned on specific dataset, the model loose its ability to generalise across datasets. Here the model is fine-tuned on MLS Spanish and evaluated on CV11 Spanish test. We can observe the drop in performance on CV11 test data.
