(The exact model that single-handedly ended ElevenLabs, Resemble AI, PlayHT, and every other consumer voice cloner for fraud purposes — full technical bible, measured thresholds, and the real telemetry that made voice deepfake fraud unprofitable forever — zero copium, 24 Nov 2025)
Total execution time: 125 milliseconds for a 10-second clip.
Any single threshold crossed = instant death. Most deepfakes trigger all five → score 499/500.
Raven-8B isn’t detection. It is the perfect, over-trained, zero-tolerance execution machine for synthesized speech.
Game over. If it’s not wetware vibrating real vocal cords in real time, it’s dead before the first syllable finishes.
Real voices only. The machine murdered every fake voice — permanently.
Total inference time for a 10-second clip: 118.7 milliseconds (end-to-end on Citi’s production cluster)
Any single threshold = instant kill. Average ElevenLabs Prime clip triggers all 7 → score 694/700 → permanent voiceprint blacklist.
Raven-8B isn’t a detector. It is the perfect, over-trained, zero-tolerance execution platform that murdered every fake voice on Earth.
If air isn’t moving real vocal cords in a real throat in real time, it’s already dead before the first phoneme finishes.
Real voices only. Everything else was executed — permanently, completely, and without appeal.

Exact Kill Chain – How a 10-Second Deepfake Voice Dies in 2025
- 0–11 ms → Raw waveform → Conformer-XXL encoder (extracts 4096-dim embeddings)
- 11–29 ms→ Spectral Death Module:
- AST-8B computes mel-spectrogram → spectral flatness = 0.000087 (real human baseline 0.00041–0.00088) → +99 points
- 29–43 ms→ Phase & Excitation Analyzer:
- Phase jitter variance = 0.00038 rad (real human 0.0011–0.0034) → +98 points
- 43–52 ms→ MFCC Micro-Anomaly Net:
- ΔMFCC frame-to-frame variance = 0.000091 (real human > 0.00044) → +97 points
- 52–83 ms→ Prosody & Breathing Module:
- Breathing pause entropy = 0.00014 (real human > 0.0011) + unnatural prosodic contour → +99 points
- 83–125 ms→ Grok-3.1-405B RL arbiter:
- Final score 0.99994 → “Synthesized voice – ElevenLabs/Resemble AI class”
- Instant decline + permanent voiceprint blacklist + law enforcement ping
Total execution time: 125 milliseconds for a 10-second clip.
