</div>
This dataset is a curated compilation of **[SECoMiCSC](https://magichub.com/datasets/chinese-english-code-mixing-conversational-speech-corpus/)**, **[DevCECoMiCSC](https://magichub.com/datasets/dev-set-of-chinese-english-code-mixing-conversational-speech-corpus/)**, and **[BAAI/CS-Dialogue](https://huggingface.co/datasets/BAAI/CS-Dialogue)**, specifically processed for Code-Switching ASR research.

## Usage
```python
from datasets import load_dataset, Audio
# Load with streaming (Recommended)
data = load_dataset("1uckyan/code-switch_chunks", split="train", streaming=True)
# Important: Cast to 16kHz
data = data.cast_column("audio", Audio(sampling_rate=16000))
for sample in data:
print(f"Source: {sample['source']} | Text: {sample['sentence']}")
break
```
## Data Sources & Creation
| Source Dataset | Original Content | Processing / Cleaning Logic |
| --- | --- | --- |
| **SECoMiCSC** | Conversational Speech | **VAD-based Chunking**: Split >1.8s gaps, merged to 5-15s segments.
| **DevCECoMiCSC** | Conversational Speech | **VAD-based Chunking**: Same as above. |
| **BAAI/CS-Dialogue** | Dialogue | **Tag Filtering**: Only retained utterances tagged as <MIX>
## Reproducibility
We provide the `data_preparation.py` script in this repository to ensure the transparency and reproducibility of our data processing pipeline.
If you have access to the raw source datasets, you can recreate this specific processed version by running:
```bash
python data_preparation.py \
--secomicsc_root /path/to/local/ASR-SECoMiCSC \
--dev_root /path/to/local/ASR-DevCECoMiCSC \
--cs_dialogue_root /path/to/local/CS_Dialogue/data/short_wav \
--output_dir ./output_Dataset
```
