# wav2vec2-large-xls-r-300m-bashkir-cv7_opt

This model is a fine-tuned version of [facebook/wav2vec2-xls-r-300m](https://huggingface.co/facebook/wav2vec2-xls-r-300m) on the MOZILLA-FOUNDATION/COMMON_VOICE_7_0 - BA dataset.
It achieves the following results on the evaluation set:
- Training Loss: 0.268400
- Validation Loss: 0.088252
- WER without LM: 0.085588
- WER with LM: 0.04440795062008041
- CER with LM: 0.010491234992390509


## Model description

Trained with this [jupiter notebook](https://drive.google.com/file/d/1KohDXZtKBWXVPZYlsLtqfxJGBzKmTtSh/view?usp=sharing)



## Intended uses & limitations

In order to reduce the number of characters, the following letters have been replaced or removed:

- 'я' -> 'йа'
- 'ю' -> 'йу'
- 'ё' -> 'йо'
- 'е' -> 'йэ' for first letter
- 'е' -> 'э' for other cases
- 'ъ' -> deleted
- 'ь' -> deleted

Therefore, in order to get the correct text, you need to do the reverse transformation and use the language model.
