## 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 |
|
|
``` |

|
|
| 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 |
|
|
|
|
|
``` |
