+# Dataset Summary
+
+**Kachin ASR Audio** is a collection of speech data in the Kachin (Jinghpaw) language, sourced from publicly available news, ethnic-language radio broadcasts, and government communication programs. The dataset includes narration, interviews, and spoken reports from outlets such as PVTV, Voice of NUG, and regional ethnic news platforms. It is designed to support the development of automatic speech recognition (ASR) systems for low-resource indigenous languages in Myanmar.
+
+Each audio file is paired with metadata including the original filename and duration. The dataset is distributed in WebDataset `.tar` format for efficient streaming and scalable training workflows.
+
+
+## Supported Tasks and Use Cases
+
+This dataset is primarily intended for:
+
+- **Automatic Speech Recognition (ASR)**: Training and evaluating models that transcribe spoken Kachin into text.
+- **Low-Resource Language Research**: Developing language models, acoustic models, or linguistic tools for indigenous languages.
+- **Speech Corpus Alignment**: Providing a foundation for aligning future Kachin-language transcriptions or translations.
+- **Government and News Voice Modeling**: Supporting speech synthesis, diarization, or speaker identification tasks using public-domain voices.
+
+Researchers, linguists, and developers working on Southeast Asian NLP or multilingual ASR systems can benefit from this dataset.
+
+## Dataset Structure
+
+The dataset is packaged as a single `.tar` archive in [WebDataset](https://github.com/webdataset/webdataset) format. Each sample consists of:
+
+- `<key>.mp3` — the audio file containing a speech segment in Kachin
+- `<key>.json` — a metadata file with the following fields:
+  - `file_name`: standardized filename (e.g., `00001.mp3`)
+  - `original_file`: original filename before chunking (e.g., `001.mp3`)
+  - `duration`: length of the audio segment in seconds (float)
+
+All files are stored inside a `train/kachin.tar` archive, allowing for efficient streaming and batched processing using WebDataset-compatible tools.
+
+## Data Splits
+
+This release provides a single `train` split containing all available audio chunks.
+
+- **Train**: 6,786 audio segments
+- **Validation/Test**: Not included in this version
+
+If needed, users can partition the dataset into training, validation, and test sets using random sampling, duration thresholds, or speaker-based segmentation strategies.
+
+## Dataset Creation and Sources
+
+This dataset was curated from publicly available audio sources, including:
+
+- **PVTV (People’s Voice Television)** — a public-facing media channel broadcasting government and community news
+- **Voice of NUG** — speech excerpts from the National Unity Government (NUG) of Myanmar
+- **Ethnic Language Programs** — regional news and educational radio clips in the Kachin (Jinghpaw) language
+
+All audio was downloaded directly from public YouTube channels and online radio archives. The content is in the public domain or covered under open broadcast use, making it legally shareable for research and development purposes.
+
+Audio segments were chunked using a combination of silence-based segmentation and manual review. Only segments containing clear speech were retained.
+
+## Licensing and Limitations
+
+This dataset is released under the [Creative Commons Zero (CC0 1.0)](https://creativecommons.org/publicdomain/zero/1.0/) license, placing it in the public domain.
+
+### ✅ Permitted Uses
+- Academic and commercial use
+- Fine-tuning and publishing ASR models
+- Linguistic research on Kachin/Jinghpaw language
+- Audio analysis, transcription, and synthesis
+
+### ⚠️ Limitations
+- No transcripts are currently included — this is audio-only metadata
+- Audio may contain background music, radio effects, or variable recording quality
+- Speaker identities are not labeled or anonymized
+
+Please respect cultural and ethical norms when using indigenous voice data in production systems or media.
