| # 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. |
