High-Security Banking
A bank-grade voice agent designed for high-value financial transactions. Combines voiceprint biometrics with PIN verification for dual-factor authentication, uses voice approvals (HITL) before executing sensitive transactions, and supports conference calling to bring in a supervisor for large transfers.Voice Features Used
| Feature | Purpose |
|---|---|
| Voice Biometrics | Voiceprint verification as first authentication factor |
| Caller Authentication | PIN entry via DTMF as second factor |
| Voice Approvals (HITL) | Verbal confirmation before executing transactions |
| Conference Calling | Add supervisor for high-value transaction co-approval |
| Compliance & Security | Recording consent, guardrails, blocked topics |
| Hold / Resume | Hold while verifying transactions |
| Sentiment Escalation | Transfer to supervisor if caller becomes frustrated |
| Call Recording | Full call recording for audit trail |
How It Works
Caller: "I need to transfer $15,000 to my savings account."
-> Voice biometrics: "Please say: My voice is my password"
-> PIN verification: "Please enter your 4-digit PIN"
-> Both pass: "Identity verified. Welcome back, John."
-> Voice approval: "I'd like to transfer $15,000 to your savings. Should I proceed?"
-> Caller: "Yes, go ahead."
-> Amount > $10,000: "For a transfer this large, I'd like to bring my supervisor on the line for co-approval."
-> Conference call with supervisor
-> Transaction executed
