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 (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.
