Development of AI Voice Biometrics Verification System
Voice biometrics replace secret questions and PINs for customer identification. User just speaks — system compares voice with stored reference. Used in banks, call centers, mobile apps.
System Architecture
- Enrollment: register voice profile (3–5 recordings, 5–15 sec each)
- Verification: compare new voice against enrollment samples
- Anti-spoofing: detect synthetic voices
- Speaker recognition: ECAPA-TDNN or similar model
Active vs Passive Biometrics
Active: user pronounces set phrase ("My voice is my password")
- EER: 0.5–1.5%
- High security
Passive: user speaks naturally during operator conversation
- EER: 2–5%
- More convenient, lower security
Requirements
Minimum audio length:
- Enrollment: 5+ seconds per sample
- Verification: 3+ seconds
- Passive verification: 8+ seconds
Compliance
152-FZ "On Personal Data": voice biometric data is special category. Requires explicit consent, separate storage, right to deletion.
Timeline: biometric verification system — 6–8 weeks. With anti-spoofing and compliance — 3–4 months.
