One challenge. Every call.
Maximum protection.
Vocos Bouncer screens every incoming call against dozens of signals - acoustic forensics, prosody, formants, temporal artifacts, and behavioral patterns. Humans pass. Synthetic voices don't.
Sub-second bouncer
Every call screened in under a second. No friction for real callers - deepfakes blocked at the door, before they ever reach your agent.
Drop-in bouncer
One endpoint. Send audio, get verified or blocked. Wire the bouncer into any voice agent in hours, not months.

Sits in front of any voice agent
Vocos Bouncer drops into any voice stack. A few lines of code and every incoming call is screened before it hits your agent.
Dozens of signals
Forensics 0.3B plus prosody, formants, spectrogram artifacts, and behavioral patterns. Confidence scores and explanations for every challenge.
Beyond pass / block
Every cleared call comes with structured intelligence - age, gender, intent, emotion. Your agent doesn't just trust the caller, it knows them.
Voice fraud is exploding.
Your agent needs a bouncer.

Frequently asked questions
Everything you need to know about Vocos.
Today's AI can clone any voice in just 3 seconds. That's incredible technology - but it also means anyone can impersonate anyone. Voice agents are the new front door for businesses, and they need protection. Vocos exists to make sure your voice AI can't be weaponized against you.
Vocos is the only comprehensive solution for voice agent protection. We're purpose-built for voice agent security - not adapted from a generic audio tool. We detect the most recent TTS and voice cloning methods that others miss, integrate in minutes with any voice stack, and go beyond security with audio intelligence features like age, gender, and intent detection - so you know your caller and can adjust your flow in real time.
One credit equals one screened call. Pro costs $0.01 per credit. The free plan includes 100 free credits.
Under 1 second. Forensics 0.3B runs on dedicated infrastructure and returns a verdict with a confidence score in real time - fast enough to use inline during a live call, not just after the fact. We also support faster inference for special cases - contact us for more details.
Forensics 0.3B is trained on over 5 million audio samples spanning more than 100 of the latest TTS systems and attack vectors, including the voice-cloning models active in fraud attacks today. It excels on every public deepfake benchmark we've tested, achieving >99% on the In-the-Wild dataset (the industry-standard real-world test) and 99.5% on our internal 2026 evaluation set. That said, no detection model is perfect - Forensics can make mistakes, so treat its verdict as a strong signal alongside your other defenses, not the sole arbiter. The model is updated continuously to handle new threats, so individual benchmark scores can shift up or down over time.
Security is in our DNA. All communication is encrypted in transit, and your data is protected by enterprise-grade infrastructure.
We're deep learning researchers with elite military intelligence experience. We've spent years building AI systems in high-stakes environments, and now we're making that level of security accessible to every developer and business. Reach out: eliya@vocos.io.
