This model is fine-tuned from [microsoft/Phi-4-multimodal-instruct](https://huggingface.co/microsoft/Phi-4-multimodal-instruct) on [Bingsu/zeroth-korean](https://huggingface.co/datasets/Bingsu/zeroth-korean), [google/flerus](https://huggingface.co/datasets/Bingsu/google/flerus) in 5 epochs.

This model is trained 960 steps on datasets for Korean Audio Speech Recognition on H100.
|
| 55 |
|
| 56 |
+
After that, we continue training with [CoVoST2 Dataset](https://huggingface.co/datasets/junnei/covost2) / [Only for Korean](https://huggingface.co/datasets/junnei/covost2-ko) for AST.

## Evaluation
|
| 59 |
|
| 60 |
+
Evaluation was done on the following datasets:
|
| 61 |
+
- ASR (Automatic Speech Recognition): Evaluated with CER (Character Error Rate) on zeroth-test set (457 samples).
|
| 62 |
+
- AST (Automatic Speech Translation): Evaluated with BLEU score on fleurs ko <-> en speech translation result (270 samples).
|
| 63 |
|
| 64 |
+
Script is retrieved from [here](https://gist.github.com/seastar105/d1d8983b27611370528e3b194dcc5577#file-evaluate-py).
|
| 65 |
|
| 66 |
+
Compared to [Phi-4-mm-inst-zeroth-kor](https://huggingface.co/seastar105/Phi-4-mm-inst-zeroth-kor) and [Phi-4-multimodal-finetune-ko-speech](https://huggingface.co/daekeun-ml/Phi-4-multimodal-finetune-ko-speech), ASR is significantly improved.
