Voice Biometrics for Banking

Secure AI Authentication Without OTPs or Passwords

Banks are under pressure from two sides: rising fraud and rising customer expectations.

Traditional authentication methods like OTPs, PINs, and security questions are slow, vulnerable, and frustrating for customers. Fraudsters exploit SIM swaps and social engineering daily, while customers abandon journeys due to verification friction.

Voice biometrics for banking replaces these outdated methods with AI-powered voice authentication that verifies identity instantly, securely, and passively during natural conversation.

No OTPs.
No passwords.
No interruptions.

Just seamless, enterprise-grade authentication.

What Is Voice Biometrics for Banking?

Voice biometrics uses artificial intelligence to identify customers based on unique vocal characteristics such as pitch, tone, cadence, and speech dynamics.

Each customer has a voiceprint created during enrollment or natural interaction. During future calls or voice sessions, AI compares live speech against the stored voiceprint to authenticate identity in real time.

Authentication happens while the customer speaks.

No extra steps. No added friction.

Why OTP-Based Authentication No Longer Works

OTP authentication was built for a different era. Today, it creates more risk than protection.

OTPs introduce friction

Customers wait for messages, switch apps, and manually enter codes. Delays increase drop-offs and dissatisfaction.

OTPs are vulnerable to fraud

SIM swap attacks, SMS interception, and phishing make OTPs easy to bypass.

OTPs increase operational costs

In call centers, OTP verification adds 30 to 60 seconds per interaction, multiplying agent workload.

OTPs damage customer experience

Repetitive verification steps break conversational flow and reduce trust.

Banks need authentication that is invisible, instant, and secure.

Key Banking Use Cases

Call Center Authentication

Authenticate customers within seconds of conversation start. Reduce average handle time by up to 40%.

Digital Banking Access

Enable passwordless login for IVR and voice assistants.

High-Risk Transactions

Add biometric verification for fund transfers, profile changes, and sensitive actions.

Fraud Prevention

Detect spoofed, replayed, and synthetic voices in real time.

Collections and Account Servicing

Verify identity before discussing financial data while maintaining conversational flow.

Built-In Anti-Spoofing and Deepfake Detection

Modern fraud is AI-driven. Your defense must be AI-driven too.

Inya Workforce analyzes:

• Acoustic inconsistencies
• Playback artifacts
• Speech micro-patterns
• Synthetic voice signatures

This blocks replay attacks and deepfake attempts before authentication completes.

Risk scoring automatically flags suspicious sessions for further verification.
