This model is fine-tuned from microsoft/Phi-4-multimodal-instruct on Bingsu/zeroth-korean, google/flerus in 5 epochs.

This model is trained 960 steps on datasets for Korean Audio Speech Recognition on H100.

After that, we continue training with CoVoST2 Dataset / CoVoST2-Ko for AST.

AST Finetuned model is Here : Phi-4-multimodal-instruct-ko-speech

Evaluation

Evaluation was done on the following datasets:

• ASR (Automatic Speech Recognition): Evaluated with CER (Character Error Rate) on zeroth-test set (457 samples).
• AST (Automatic Speech Translation): Evaluated with BLEU score on fleurs ko <-> en speech translation result (270 samples).

Script is retrieved from here.

Compared to Phi-4-mm-inst-zeroth-kor and Phi-4-multimodal-finetune-ko-speech, ASR is significantly improved.
