Various embodiments of the technology described herein alleviate the need to specifically request enrollment information from a user to enroll the user in a voice biometric authentication program. For example, the system can receive a verbal request or a verbal command and non-voice biometric authentication information from a user. The user can be authenticated via a first authentication method using the non-voice biometric authentication information. After the user is authenticated using the first authentication method, the system enrolls the user into a voice biometric authentication program for at least one portion of the verbal request or the verbal command without requesting enrollment information.
