FAQs
Hiya AI Voice Detection is part of Hiya Protect and uses AI to identify synthetic, deepfake, or AI-generated voices during live phone calls. It helps detect voice-based scam and impersonation attempts in real time.
The technology is used today to help protect consumers through Hiya-powered phone apps and can also be deployed at the network level by mobile operators and device manufacturers. It is designed to support broader fraud-prevention use cases as voice-based attacks continue to evolve.
Hiya AI Voice Detection is built to identify a range of voice-based fraud techniques, including synthetic and AI-generated voices, deepfake impersonation, and other manipulated audio patterns commonly used in social engineering attacks. These techniques are designed to mimic real people, making them difficult to detect with traditional fraud controls.
Hiya AI Voice Detection analyzes voice characteristics during live phone calls using machine learning models trained to recognize patterns associated with synthetic or manipulated audio. The system evaluates signals in real time, allowing teams to identify suspicious calls as they happen without disrupting the customer experience.
STIR/SHAKEN helps authenticate the phone number making a call, and spam blocking focuses on call reputation and labeling. Hiya AI Voice Detection addresses a different risk: whether the voice itself is real or synthetic. It adds protection in scenarios where phone numbers may appear legitimate but the caller’s voice is fraudulent.
Hiya AI Voice Detection is designed to protect phone calls from AI-generated, synthetic, and impersonated voices across a wide range of use cases.
