Abstract
Systems and methods for authenticating a user using a voice activated device. The method includes receiving first data representing a user identifier corresponding to a user and second data representing a device identifier corresponding to the voice activated device. The method further includes determining user metadata corresponding to the user identifier and a device audio type corresponding to the device identifier. The method also includes calculating a risk score based on the user metadata. The method further includes calculating a length of spoken voice utterance based on the calculated risk score. The method also includes receiving and processing third data representing a spoken voice utterance having the calculated length corresponding to the user using the voice activated device. The method further includes validating the user in response to determining that the processed third data substantially matches the voiceprint associated with the user.
