Usage

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

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:

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
