# wav2vec2-large-xlsr-53-urdu

This model is a fine-tuned version of [Harveenchadha/vakyansh-wav2vec2-urdu-urm-60](https://huggingface.co./Harveenchadha/vakyansh-wav2vec2-urdu-urm-60) on the common_voice dataset.
It achieves the following results on the evaluation set:
- Loss: 11.4593
- Wer: 0.5772
- Cer: 0.3384

## Model description

The training and valid dataset is 0.58 hours. It was hard to train any model on lower number of so I decided to take Urdu checkpoint and finetune the XLSR model.

## Training and evaluation data

Trained on Harveenchadha/vakyansh-wav2vec2-urdu-urm-60 due to lesser number of samples. Persian and Urdu are quite similar. 

## Training procedure
