+# VibeVoice Final Samples — the whole story in audio
+
+Joint-finetuned VibeVoice-1.5B (LLM-LoRA + full diffusion head, warm-started chain
+fullv3 -> emo3 -> emo4). All samples generated with our emotion-steering stack.
+
+## Listening order
+1. **01_dialogue_baseline_stock** — stock VibeVoice (the read-only baseline)
+2. **02_dialogue_our_model_fullv3** — OUR model, ear-certified intelligible dialogue
+   (WER 0.36 vs stock 0.03; 5 prior head-only attempts produced babble — this is the joint-training proof)
+3. **03_dialogue_polished_joint2** — the polished twin (more training: a wash statistically, different samples)
+4. **04_emotion_reference_steering_cremad** — R1: swap the reference clip's EMOTION (same actors,
+   same dialogue): ANGRY_ANGRY / SAD_SAD / **ANGRY_SAD_mixed** (the per-speaker money clip).
+   Note: CREMA-D actors carry non-US accents — the accent transfer is itself evidence of total reference conditioning.
+5. **05_emotion_us_accent_palette** — R1 US-accent (RAVDESS): same sentence, same voice, 8 emotions
+   (measured F0 tracks emotion: ANGRY 328 Hz ... SAD lowest)
+6. **06_emotion_3speaker_drama** — 3-speaker scene: angry / fearful / surprised in one conversation
+7. **07_emotion_per_turn_switch** — same actor goes ANGRY -> relieved mid-dialogue (dual-slot authoring)
+8. **08_ship_config_emo4_20ddpm** — THE SHIP CONFIG: emo4 (clean-data scale-up) at 20 DDPM steps,
+   <emotion> tags + matching references. tag2_tags_matching_refs_BEST.wav = the final product demo.
+9. **09_quality_ab** — the quality diagnosis: the 'webcam-mic static' was REFERENCE-carried
+   (CREMA-D refs: noise floor 0.006 in generation vs 0.0001-0.0004 with clean refs; 20 DDPM steps = 4x high-band)
+

+
+## Metrics
+- Intelligibility: our model WER 0.32-0.41 band vs stock 0.03 (single-run; run-to-run +-0.1)
+- Speaker identity: SIM 0.92-0.93 vs stock 0.94
+- Emotion: F0 shifts 300->184 Hz (reference steering); tag channel -87 Hz with refs held constant
+- Speed: architecture-bound ~1.4-1.5x slower than stock (launch-bound; measured ceiling)
