IDLive®️ Voice — Voice Liveness Detection

Why choose voice biometrics components from Mitek?

Passive, frictionless experience

Users can be authenticated during natural conversation without passwords, scripted phrases, enrollment prompts, or verification delays. This streamlined authentication is ideal for mobile apps, and voice-enabled services.

API-first, developer friendly design

Components are designed for speed and scalability. They can be deployed via lightweight SDKs on-premises, within a private cloud, or on-device. Just a single API endpoint is needed to access verification, spoof detection, and clone detection.

Thorough voice fraud detection

Voice anti-spoofing capabilities are complementary, covering playbacks, impersonation, synthetic attacks, deepfake voice clones, and emerging threats from generative AI and synthetic audio.

High accuracy with minimal data

State-of-the-art AI models require just a few seconds of audio for speaker verification and perform in noisy, real-word conditions. They are text-independent and can verify identity regardless of specific words or dialects.

Defend yourself with Mitek solutions against different types of voice-based spoofing attacks

Bad actors use different techniques to impersonate voices and deceive biometric authentication systems.

Advanced speech synthesis

Using computer generated speech from text to impersonate a person’s voice at authentication.

Recorded replays

Capturing a recording of a real person’s voice and replaying it for an authentication without their knowledge or permission.

Deepfake voice clones

Using AI to simulate a real voice by analyzing a sample of the person’s voice to understand its unique characteristics.

Voice conversion

Altering a person’s voice to sound like another person’s using digital processing technologies.

FREQUENTLY ASKED QUESTIONS

What is voice biometric authentication?

Voice biometric authentication is the science of using a person’s voice as a uniquely identifying biological characteristic to authenticate their identity.

What is voice verification? Is it the same as voice authentication?

Voice verification and voice authentication are often used interchangeably to mean using a person’s unique biological voice characteristics as a means of confirming their identity.

What is a voiceprint?

A voiceprint is a unique digital representation of a person’s voice that can be used for secure identity authentication. It includes attributes such as pitch, tone, and accent. Like a fingerprint, a voiceprint is unique to a specific person.

What are the key benefits of voice biometric authentication?

Voice biometric authentication supports fast, frictionless, and secure identity authentication. It isn’t based on something that users know (like a password) or something that they have (like a mobile phone). These things can be forgotten or lost, while a person’s voice is unique only to them.

How does voice authentication improve customer experience?

Voice authentication improves the customer experience because it is completely frictionless. Customers avoid the frustration of remembering passwords, PINs, or challenge-based questions. It’s also faster and more secure than one-time passcodes (OTP).

Can voice biometrics reduce operational costs?

Yes, voice biometrics can significantly reduce operational costs, especially where there is a high-volume of customer interactions, such as contact centers. Savings are realized from faster authentication, agent efficiency, reduced fraud losses and lower investigation costs.

How secure is voice biometric authentication?

Voice biometric authentication offers a strong layer of defense against fraud. Like any security technology, it’s not foolproof and heavily depends on the implementation, but voice authentication provides greater security than traditional knowledge-based authentication methods like passwords and PINs.

Can voice biometrics be fooled by recordings or voice impersonations?

Voice biometrics are not immune to threats and rapidly advancing technologies are making it easier for bad actors to spoof real human voices. However, liveness detection and advanced AI analysis are also improving voice biometric systems, ensuring they remain a robust security mechanism.
