Passive Voice BiometricsPassive Voice Biometrics authenticates and enrols users without them needing to do anything additional to their reason for calling or interacting with a speech service. authenticationAuthentication is the call centre security process step in which a user's identity is confirmed. We check they are who they claim to be. It requires the use of one or more authentication factors. often occurs in the call background as the user is speaking to an agent or interacting with a speech-driven application. Because the user is not required to do anything that they would not otherwise have done, we refer to this as Passive.
The genuine user will usually have completed enrolmentEnrolment is a step in the registration process where specific utterances are requested from the user or previously acquired audio is used to create a Voice Biometric template (Voiceprint) for subsequent use in Authentication/Identification. during registrationRegistration is the business process where a user is offered, consents to, and completes a Voice Biometric service enrolment. on a previous interaction with an agent or automated system. The only additional effort required for registration is the provision of consentConsent is a step in the registration process where a user provides permission to process their biometric data before enrolment in a Voice Biometric system in a way which complies with applicable data protection and privacy legislation. when this is required.
This approach typically depends on the use of Text Independent Voice BiometricsVoice Biometrics uses the unique properties of a speakers voice to confirm their identity (authentication) or identify them from a group of known speakers (identification). technology, has higher user acceptance rates but requires longer audio durations for both enrolment and authentication.
Good examples of Passive Voice Biometrics are:
