Text-Dependent Voice Biometrics

Most often used in automated systems with an Active Voice BiometricsActive Voice Biometrics is an approach to using Voice Biometrics that requires the user to say additional utterances that would not otherwise have been required when calling or interacting with a speech service for authentication or enrolment. approach. The biometric algorithm is optimised for how the user speaks the specific passphrase. As a result, it only requires short utterances for 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. and 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./identificationIdentification is call centre security process step in which an individual record is found in the organisation's systems of record. In this step users claim an Identity.. This approach may also substitute the passphrase with a random digit challenge and response, telephone or account numbers or even a passphrase the customer has chosen themselves, but they all require the customer to record the specific words in advance.
