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

This model is a fine-tuned version of 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

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.
