# Whisper Small Norwegian Bokmål

This model is a fine-tuned version of [openai/whisper-small](https://huggingface.co/openai/whisper-small) trained on several datasets.

It is currently in the middle of a large training. Currently it achieves the following results on the evaluation set:
- Loss: 0.3230
- Wer: 15.56

## Model description

The model is trained on a large corpus of roughly 5.000 hours of voice. The sources are subtitles from the Norwegian broadcaster NRK, transcribed speeches from the Norwegian parliament and voice recordings from Norsk Språkteknologi. 

## Intended uses & limitations

The model will be free for everyone to use when it is finished.
