# DuplexChat
large-scale, two-speaker, full-duplex
spoken-dialogue corpus built from public podcast feeds. This repository
distributes **no audio**
## Contents
| File | Rows | Hours |
|------|-----:|------:|
| `duplexchat_manifest_en.jsonl.gz` | 15,304,412 | 282,634 |
| `duplexchat_manifest_ja.jsonl.gz` | 7,329,011 | 132,723 |
`manifest_counts.json` holds the same totals.
## Row schema
Each line is one two-speaker dialogue clip:
```json
{
"language": "en-us",
"rss_url": "https://.../podcast/rss",
"audio_url": "https://.../episode.mp3",
"dialogue_idx": 1,
"episode_start_sec": 80.22,
"episode_end_sec": 708.44,
"duration_sec": 628.22,
"speakers": ["SPEAKER_04", "SPEAKER_02"],
"episode_duration_sec": 2165.52
}
```
- `rss_url` — the source podcast feed.
- `audio_url` — the source episode audio (download target).
- `episode_start_sec` / `episode_end_sec` — the dialogue span within the episode.
- `duration_sec` — span length.
- `speakers` — the two diarized speaker labels for the clip.
Rows are deduplicated globally by `(audio_url, dialogue_idx)`.
## Reconstruction
1. Download the episode at `audio_url`.
2. Slice the segment `[episode_start_sec, episode_end_sec]`.
3. Re-run the speech separation/restoration to
recover one-speaker-per-channel stereo audio.
The construction pipeline is released separately.
