Detect synthetic voice
in contact centers.
Protect contact centers against voice cloning and AI deepfakes. VIONIS evaluates acoustic vocoder artifacts, conversational turn latency, and semantic challenges in real-time call streams.

Voice cloning bypasses
traditional authentication.
Generative voice models clone customer voices with seconds of reference audio. Robust verification requires analyzing physical acoustic anomalies, live turn-taking dynamics, and contextual reasoning.
Generative voice cloning
Synthetic AI models replicate vocal timbre and cadence. Perceptual familiarity alone is insufficient to authenticate high-risk requests.
Telephony compression artifacts
Band-limited 8 kHz telephony codecs (G.711) mask synthetic anomalies, requiring isolated dual-channel analysis.
Conversational latency anomalies
Automated voice bots exhibit anomalous turn delays, rigid response timing, and scripted semantic failures under interruption.
Three complementary
verification layers.
Vionis Flash combines acoustic and turn-taking features. The semantic challenge below is a separate concept demonstration and is not part of the Flash verdict.
Spectral signature & vocoder analysis
Analyzes frequency spectra, harmonic distribution, and neural vocoder artifacts to identify synthetic or replayed audio streams.
Four-stage telephony
verification pipeline.
Submit stereo WAV call recordings and receive a caller classification from Vionis Flash.
Analyze call audio
for synthetic indicators.
Upload a dual-channel WAV recording and let Vionis Flash classify Caller CH0 using acoustic and conversational evidence.

Ready when you are
Choose a call recording, then run analysis.
Model classification does not verify caller identity. Confidence is the score for the returned verdict.
Caller CH0 is classified. Agent CH1 provides turn-taking context.
Acoustic features and conversational timing, with a degraded-line fallback.
Run analysis submits the original WAV to Flash. Results stay in this session.
REST API for contact center
fraud prevention.
Integrate synthetic voice detection into your SIP gateway, IVR, or agent desktop. Submit call audio to /detect for a verdict, or /explain for measured features and model diagnostics.
/detectLIVE FLASH API{ "call_id": "call-001", "audio_base64": "<complete stereo WAV as base64>", "sample_rate": 8000, "channels": 2}Verify caller authenticity in real time.
Test sample calls in the console, inspect layer evidence, or integrate directly via the REST API.
