## Descriptions
FireRedChat-punc is a fine-tuned `hfl/chinese-lert-base` model designed for punctuation restoration, primarily for post-processing in [FireRedASR](https://github.com/FireRedTeam/FireRedASR). 

The model restores the following punctuation marks: [， 。 ？ ！]. It supports both Chinese and English text, enhancing the readability of transcribed text.

## Roadmap
- [x] 2025/09
  - [x] Release the fine-tuned punctuation restoration model.

## Usage

RedPost source code [github](https://github.com/FireRedTeam/FireRedChat/tree/main/fireredasr-server/server/redpost)
Below is an example of how to use the FireRedChat-punc model for punctuation restoration:

```bash
git clone https://huggingface.co/hfl/chinese-lert-base FireRedChat-punc/chinese-lert-base
```

```python
import os
from redpost import RedPost, RedPostConfig

punc_model_dir = "./FireRedChat-punc"
post_config = RedPostConfig(
    use_gpu=True,
    sentence_max_length=30
)
post_model = RedPost.from_pretrained(punc_model_dir, post_config)
batch_post_results = post_model.process([text], ["text"])
text = "".join([r["punc_text"] for r in batch_post_results])
text = re.sub("<unk>|<UNK>|\[unk\]|\[UNK\]", "", text)
print(text)
```

## Use with FireRedASR

This punctuation restoration model can be used together with FireRedASR, refer to [fireredasr-server](https://github.com/FireRedTeam/FireRedChat/blob/main/fireredasr-server/README.md) for setup instructions.
