Abstract: Systems and methods are provided for facilitating voice authentication of a user in connection with a network transaction. One example method includes capturing, by a voice interactive device, a voice command from a user to initiate a transaction with a third party and determining content of the voice command. The method then includes authenticating the user, based on the captured voice command and a voice biometric reference associated with an identifier for at least one of the user and/or the voice interactive device, and transmitting, by the voice interactive device, a purchase request for the transaction consistent with the content of the voice command to the third party. The purchase request includes an indication of biometric authentication for the user, whereby the third party is permitted to initiate an enhanced authentication of the user in connection with the transaction.
