# ESPnet3 asr model

Packed model bundle generated from `egs3/mini_an4/asr`.

## Model

- Repository: `ms180/CI_mini_an4_training_asr_transformer`
- Recipe: `egs3/mini_an4/asr`
- Task: `asr`
- System: `espnet3.systems.asr.task.ASRTask`
- Creator: `masao`
- Created: `2026-05-11T19:28:10`
- Branch: `espnet3/publish_stage`
- Commit: `a0087239784f92b800ee9f12878af6cdb0e10c63` (`a008723978`)
- Worktree: dirty
- Origin: git@github.com:Masao-Someki/espnet.git

## Usage

```python
from espnet3.publication import InferenceModel

model = InferenceModel.from_pretrained("ms180/CI_mini_an4_training_asr_transformer", trust_user_code=True)
result = model(sample)
```

## Packaging

- Bundle: `model_pack`
- Exp dir: `./exp/training_asr_transformer`
- Strategy: `copy experiment outputs; include extra recipe assets; register named artifact files; apply exclude filters`

## Results

| dataset | CER | WER |
| --- | --- | --- |
| test | 213.43 | 100.0 |
| valid | 933.33 | 100.0 |
