| # FD_data_v1 — synthetic full-duplex spoken conversations |
|
|
| A small demo batch of fully synthetic two-speaker conversations with |
| scripted turn-taking events and construction-time ground-truth timestamps. |
| Voices are synthesized with [Kokoro-82M](https://huggingface.co/hexgrad/Kokoro-82M) |
| (Apache-2.0); transcripts are synthetic and contain no personal data. |
|
|
| Each row is one two-speaker conversation: |
|
|
| - `audio`: stereo 24 kHz WAV — **channel 0 = user, channel 1 = assistant**. |
| Overlap (backchannels, interruptions) is real simultaneous audio across |
| channels. |
| - `policy` / `instruction`: turn-management conditioning |
| (none | interrupt | listen | backchannel | continue | acknowledge — |
| taxonomy after Instruct-FD, arXiv 2607.20460). |
| - `turns`: JSON — per turn: speaker, text, absolute start/end, word-level |
| onset/end timestamps (MMS forced alignment), `cut` + `unspoken` tail when |
| the turn was interrupted (the full reference text is retained). |
| - `events`: JSON — scripted-event ground truth with realized timestamps |
| (pause / assistant_backchannel / assistant_interrupt / user_backchannel / |
| user_interrupt). Timestamps are constructed, not estimated. |
| - `fidelity`: JSON — per-clip whisper-large-v3-turbo script-fidelity ratios. |
| - `verify_pass` / `verify_checks`: deterministic verdict — the event |
| structure is re-derived from the assembled audio via Silero VAD and checked |
| against the script (bc timing/shortness, interrupt onset+cut, continue |
| no-yield, acknowledge yield+adapted, pause no-takeover, listen |
| no-talk-over). |
|
|
| Timing bands (gaps, reaction latencies) are v1 PLACEHOLDERS, not yet |
| calibrated against real-corpus statistics. |
