## Model description

- **Homepage:** [SIL AI](https://ai.sil.org/)
- **Point of Contact:** [SIL AI email](mailto:idx_aqua@sil.org)
- **Source Data:** [Bloom Library](https://bloomlibrary.org/)

This model is a fine-tuned version of [facebook/wav2vec2-xls-r-300m](https://huggingface.co/facebook/wav2vec2-xls-r-300m) on the [SIL-AI/bloom-speech](https://huggingface.co/datasets/sil-ai/bloom-speech) - TGL (Tagalog) dataset.
It achieves the following results on the evaluation set:
- Loss: 0.9606
- Wer: 0.2457
- Cer: 0.0769

Users should refer to the original model for tutorials on using a trained model for inference.

## Intended uses & limitations

Users of this model must abide by the [SIL RAIL-M License](https://huggingface.co/spaces/sil-ai/model-license).

This model is created as a proof of concept and no guarantees are made regarding the performance of the model is specific situations.

## Training and evaluation data

Training, Validation, and Test datasets were generated from the same corpus, ensuring that no duplicate files were used.

## Training procedure

Standard finetuning of XLS-R was used based on the examples in the [Hugging Face Transformers Github](https://github.com/huggingface/transformers/tree/main/examples/pytorch/speech-recognition)
