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 - UK dataset.
It achieves the following results on the evaluation set:
- Loss: 0.3015
- Wer: 0.3377
- Cer: 0.0708

The above results present evaluation without the language model.

## Model description

On 100 test example the model shows the following results:

Without LM:

- WER: 0.2647
- CER: 0.0469

With LM:

- WER: 0.1568
- CER: 0.0289
