# GigaSpeech2 Vietnamese WAVs Missing Transcripts

This dataset contains the Vietnamese GigaSpeech2 training WAV files whose IDs
are absent from `train_refined.tsv`.

## Contents

- 201,295 WAV files without a matching transcript
- 41 uncompressed TAR shards in `shards/`
- 36 GB of audio (approximately)
- `processing_manifest.jsonl`: per-source-archive counts
- `summary.json`: aggregate counts
- `SHA256SUMS`: checksums for all TAR shards

Each shard preserves the original relative layout:

```text
release1/train/<archive>/<subfolder>/<utterance-id>.wav
```

The TAR files are intentionally uncompressed so they can be read sequentially
and streamed without an additional decompression layer.
