# 🇲🇲 Raw 1-Hour Burmese ASR Audio Dataset

A 1-hour dataset of Burmese (Myanmar language) spoken audio clips with transcripts, curated from official public-service media broadcasts by **PVTV Myanmar** — the media voice of Myanmar’s National Unity Government (NUG).

This dataset is intended for automatic speech recognition (ASR) and Burmese speech-processing research.

➡️ **Author**: [freococo](https://huggingface.co/freococo)  
➡️ **License**: MIT  
➡️ **Language**: Burmese (`my`)

## 📦 Dataset Summary

- **Duration**: ~1 hour
- **Chunks**: Short utterances (0.84s to 25.66s)
- **Total Samples**: 583
- **Audio Format**: `.mp3` mono files
- **Transcription Source**: Aligned manually using `.srt` files
- **Structure**: `file_name`, `transcript`, `duration_seconds`

The dataset was created entirely from public content with no modification or noise reduction applied.

## ⚠️ Data Quality Notes

- This dataset contains **raw speech audio** extracted from public media without denoising or filtering.
- Some chunks contain **background music**, instrumental intros/outros, or ambient reverb.
- Transcripts were manually aligned via subtitle files (`.srt`) and are mostly accurate.
- Estimated transcription error rate: **1–9%**, due to:
  - Minor typos or spacing issues in Burmese script
  - Occasional missing particles or honorifics

These conditions reflect real-world media audio and are left untouched to improve robustness in training and evaluation.

## 💬 Motivation

I created this dataset because I'm crazy about languages — especially Myanmar language technology.  
I noticed a severe shortage of public, modern Burmese audio datasets for speech recognition and wanted to help fix that.

This project is fully self-initiated and unfunded — no grants, sponsorships, or institutional backing. Just passion, time, and a lot of cleaning 😄  
If you find it helpful, let me know — I’d love to collaborate or help with related research!

## 🌟 In Honor of the Voices Behind the Revolution

This dataset would not exist without the tireless, fearless voices of **PVTV Myanmar** —  
🎙️ the journalists who speak truth,

They speak not from studios, but from shadows,  
not for fame, but for freedom.  
Their words echo through uncertainty,  
yet land on ears yearning for light.

> **This dataset is only a shadow of their work —

To the PVTV media team and all those risking safety to tell the truth:  
**Your voice is our history. Your courage is our future.**
