Frequently Asked Questions

Voice biometrics uses the unique characteristics of a person's voice to help verify their identity.

A voice sample is analysed and compared against an enrolled voiceprint — a mathematical representation of characteristics associated with the speaker's voice. If the biometric comparison meets the organisation's required security threshold, the interaction can be verified.

Unlike passwords, PINs or security questions, voice biometrics verifies something inherent to the person rather than relying solely on information they know or possess.

A user first enrols their voice to create a secure voiceprint.

During future interactions, Auraya analyses a new voice sample and compares it with the enrolled voiceprint to determine the likelihood that the speaker is the same person.

Authentication can occur actively, where the user is asked to speak a specific phrase or randomised challenge, or passively during natural conversation.

The appropriate approach depends on the interaction, customer experience and security requirements.

A voiceprint is a mathematical representation of characteristics extracted from a person's speech.

Rather than functioning like an audio recording, it is used by the biometric system to compare a new voice sample against the characteristics established during enrolment.

Voiceprints can be securely managed centrally, enabling organisations to use voice authentication across different customer interactions and environments.

No authentication method should be considered completely infallible or relied upon in isolation.

Auraya supports a layered approach to identity assurance, where voice biometrics can be combined with additional signals such as device and number intelligence, liveness checks, fraud intelligence and other authentication factors.

Organisations can configure security thresholds and business rules according to the risk associated with different interactions.

Auraya provides capabilities designed to identify replay attacks and recorded audio.

Depending on the authentication method, randomised challenges can require users to speak unpredictable words or numbers, making previously captured recordings significantly less useful to an attacker.

Auraya's technology can also analyse audio for indicators associated with replayed or synthetic speech.

Yes. Auraya provides deepfake and synthetic voice detection capabilities designed to identify AI-generated audio and other presentation attacks.

These capabilities can be used alongside voice authentication and fraud intelligence to provide additional protection as synthetic voice technology becomes increasingly sophisticated.

Yes. Authentication risk does not necessarily end after a person passes the initial identity check.

Auraya supports continuous voice verification, allowing the speaker to be monitored during an interaction to help identify unexpected speaker changes or other potential risks.

This enables organisations to maintain greater confidence in identity throughout the interaction rather than relying solely on a point-in-time check.

Yes. Auraya's fraud intelligence capabilities allow organisations to create and manage voiceprint watchlists containing known or suspected fraudsters.

Incoming or recorded interactions can be compared against these watchlists to help identify repeat offenders, suspicious identities and potential fraud activity.

Voice biometric systems analyse a combination of characteristics associated with an individual's speech and vocal anatomy.

While some behavioural characteristics of speech can be imitated, voice biometric comparison evaluates many characteristics simultaneously.

Auraya also supports configurable security thresholds and additional authentication signals to reduce reliance on any single biometric comparison.

Like any biometric or authentication system, voice biometrics operates probabilistically and no system can guarantee zero false accepts or false rejects.

Auraya allows organisations to configure biometric thresholds and business rules according to their security requirements and risk appetite. Higher risk interactions can also require additional authentication factors to provide greater assurance.

Auraya supports flexible deployment models designed to meet different enterprise security and data sovereignty requirements.

Depending on the deployment, biometric information can be hosted within Auraya's secure cloud environment, the organisation's own cloud infrastructure or on-premise.Voice biometric information is protected using security controls including encryption in transit and at rest.

No.

A voiceprint is a mathematical representation of characteristics extracted from speech and used for biometric comparison. It is different from the original audio recording used to generate it.

Auraya solutions can be configured to support consent and opt-out requirements.

Where a user chooses not to participate in voice biometric authentication, organisations can provide an alternative identity verification process appropriate to their regulatory and operational requirements.

Specific consent requirements vary by jurisdiction and implementation.

Auraya applies security and privacy principles throughout its technology and operations. Auraya is ISO 27001 certified and SOC 2 Type II attested, and its solutions support privacy and data protection requirements for regulated enterprise and government environments.

Biometric information is protected through measures including encryption, access controls and flexible deployment options that allow organisations to meet regional data sovereignty requirements.

Voice authentication can replace lengthy security questions, PINs and passwords with a faster, more natural identity verification experience.

Depending on the implementation, users can be authenticated during an IVR interaction, through a digital channel or passively during natural conversation.

For legitimate users, the objective is simple: stronger security with less friction.

Voice biometric systems are designed to accommodate normal variations in a person's voice.

More significant conditions that substantially affect a person's ability to speak may impact biometric performance. Organisations should therefore maintain alternative authentication methods for situations where voice verification cannot be completed reliably.

Auraya's technology can also adapt voiceprints over time as legitimate users continue to interact with the system.

Not necessarily. Auraya supports different voice biometric approaches depending on the use case. These can include specific passphrases, randomised prompts or passive verification using natural conversation. This gives organisations flexibility to balance security, customer experience and operational requirements.

Auraya's voice biometric technology is designed to support identity verification across contact centre and digital environments.

Voiceprints are centrally managed rather than being tied solely to an individual device, enabling organisations to create more consistent identity experiences across different interaction channels. The exact interoperability available will depend on the Auraya products and architecture deployed.

Yes. Auraya supports integration with leading enterprise contact centre environments, including:

• Amazon Connect
• Genesys Cloud
• Five9
• NICE CXone

Auraya's open API architecture also supports integration with other cloud and on-premise environments.

Yes.

EVA Digital is designed to complement existing enterprise identity infrastructure and can be integrated into multi-factor authentication workflows using standard identity protocols.

This allows organisations to add voice as an authentication factor without replacing their broader identity stack.

Yes. Auraya supports flexible deployment options including secure cloud, private cloud and on-premise environments.

This gives organisations greater control over security architecture, data residency and regulatory requirements.

Yes.

Auraya's technology is designed for enterprise and government environments where authentication services may need to support large user populations and high interaction volumes.

The architecture is designed to scale as transaction volumes and user populations grow without requiring organisations to continually re-platform their biometric infrastructure.

Auraya voiceprints are designed to support compatibility across system upgrades, helping organisations minimise disruption to enrolled users.

Specific migration requirements will depend on the existing implementation and target environment.

Auraya has tools and methodologies designed to help organisations migrate existing enrolled populations from legacy voice biometric platforms.

Depending on the source platform and available data, existing enrolments may be migrated without requiring every customer to complete a new enrolment process.

Auraya can assess the existing environment and recommend the appropriate migration approach.
