ErfanRou/callcc-new-data-335h

Persian call-centre ASR training windows with Soniox labels, in the same 17-column schema as ErfanRou/callcc-2k-hours-train-soniox: a drop-in for stage_callcc2k.py / build_manifests.py. Machine-labelled, not ground truth.

• Source: markmuller/call-center-prod-data, newest calls first (by upload commit), excluding every call already in callcc-2k-hours-train-soniox (incl. transcribed calls without rows), callcc-test-1k-samples-soniox and callcc-150h-soniox; dedup key call_id = sha256 of the source wav.
• Labels: Soniox stt-async-v5, language_hints=["fa"], diarization off, one job per call over a VAD-packed stream: Silero VAD v6 per channel (threshold 0.2, pad 300 ms, pauses up to 3.5 s kept), the speech of both channels laid end to end in time order with 0.25 s of silence between segments, and every token mapped back to its channel and original time. Channel attribution is exact (no diarization); label_source = soniox:stt-async-v5.
• Windows: the unmodified callcc-2k packer (5-28 s, ~15 s target, natural pauses <= 3.5 s kept, cut in silence), audio cut from the ORIGINAL channel and stored as 16 kHz mono FLAC. A window never contains audio that was not sent to Soniox: stretches that were not sent and had any VAD activity are packer barriers.
• text - Soniox words normalised (digits->words, Persian ی/ک, no punctuation, ZWNJ kept); text_raw - as emitted; conf_mean/conf_min - Soniox token confidence; text_whisper/wer_whisper/bucket - the production Whisper transcript shipped with the pool, exactly as in callcc-2k (agree < 0.10, informative 0.10-0.50 with conf >= 0.85, contested otherwise, unpaired without Whisper text).
• tokens/ - raw Soniox tokens per shard: channels (original time, callcc-2k format) plus vadpack (segment map and packed-time tokens), so windows can be re-derived without paying again. meta/calls_meta.parquet - call-level metadata joined on call_id: contains personal data from the CRM (client_metadata_json etc.; retention approved by the data owner 2026-09-17, same as callcc-2k) - keep this repo gated.
