Text-Independent Voice Biometrics

Most often used alongside agent conversations with a 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. approach. The biometric algorithm is optimised for how the speaker generally speaks. As a result, it often requires longer 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. to achieve the same level of performance as Text-Dependent Voice BiometricsA form of Voice Biometrics that is dependent on the same utterance used during enrolment being repeated during authentication or identification.. The gap is, however, closing as the technology improves. The major advantage is that these utterances can be taken from normal conversations.
