Zusammenfassung:	Improved user authentication of a communication device is provided by expanding voice biometric authentication with a dynamically updated user profile formed of non-voice usage parameters. The non-voice usage parameters are collected during successful voice authentications to establish non-voice compensation controls. When a failed voice biometric authentication attempt is followed by a valid PIN entry, then a false rejection is determined, and a voice biometric threshold is adjusted to reduce the individual user-based false rejection rate along with the enablement of the non-voice usage controls.
