Mike Swanson	6cc9043b8e	Audio processor: validated voice profiling accuracy, tuned threshold ... - Fine-grained speaker analysis (3s windows, 1s hop) across 42min episode - Host voice: 0.90-0.98 similarity (clear positive match) - Callers: 0.65-0.68 (correctly below threshold) - Produced audio/clips: 0.53-0.65 (correctly identified as non-host) - Co-host/other speakers: 0.56-0.62 (correctly identified) - Tuned host_match_threshold from 0.75 to 0.83 based on empirical data - Cross-referenced dips with transcript: correctly identifies callers, show intros, played audio clips, and station breaks - Batch transcription of 7 additional training episodes in progress Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>	2026-03-21 12:48:25 -07:00
