  • Fraud Prevention: Add an extra layer of security with voice verification

How It Works

  1. Create Verification: Add customer information and verification data through the dashboard
  2. Initiate Call: Highway calls the customer using Twilio’s voice infrastructure
  3. AI Conversation: OpenAI’s Realtime API conducts a natural conversation to verify identity
  4. Real-time Processing: Audio streams between Twilio and OpenAI via WebSocket
  5. Status Updates: Verification status updates automatically based on call results
  6. Review Results: Access detailed call logs and verification outcomes in the dashboard
Highway uses server-side voice activity detection (VAD) to ensure natural conversation flow and proper turn-taking between the AI and the customer.
