|
This model is a fine-tuned version of [facebook/wav2vec2-xls-r-1b](https://huggingface.co/facebook/wav2vec2-xls-r-1b) on the openslr dataset. |
|
It achieves the following results on the evaluation set: |
|
- Loss: 0.4239 |
|
- Wer: 0.4221 |
|
|
|
# Evaluation results on OpenSLR "test" (self-split 10%) (Running ./eval.py): |
|
- WER: 0.4490281634272114 |
|
- CER: 0.12198285179047481 |
|
|
|
# Note |
|
- Since this dataset is small (4 hours of voice recording), we decided not to train that for too long to avoid overfitting and under-generalization. |
|
- This model performs worse than its 300M-variant. Probably, we don't explore the hyper-parameter enough? |
