# wav2vec2-xls-r-300m-br

This model is a fine-tuned version of [facebook/wav2vec2-xls-r-300m](https://huggingface.co/facebook/wav2vec2-xls-r-300m) on Mozilla Common Voice 15 Breton dataset and [Roadennoù](https://github.com/gweltou/roadennou) dataset. It achieves the following results on the MCV15-br test set:
- Wer: 41.0
- Cer: 14.7

## Model description

This model was trained to assess the performance wav2vec2-xls-r-300m for fine-tuning a Breton ASR model. 

## Intended uses & limitations

This model is a research model. Usage for production is not recommended.

## Training and evaluation data

The training dataset consists of MCV15-br train dataset and 90% of the Roadennoù dataset.
The validation dataset consists of  MCV15-br validation dataset and the remaining 10% of the Roadennoù dataset.
The final test dataset consists of MCV15-br test dataset.
