Abstract
Systems and methods for authenticating a user using an interactive voice response application. The method includes receiving data representing a spoken voice utterance corresponding to a user of an interactive voice response application. The method further includes processing the data representing the spoken voice utterance based on a length and a quality of the spoken voice utterance. The method also includes comparing the processed data representing the spoken voice utterance and a voiceprint associated with the user. The method further includes generating a security token in response to determining that the processed data representing the spoken voice utterance substantially matches the voiceprint associated with the user. The method also includes receiving the security token from the interactive voice application and validating the security token corresponding to the user in response to determining that the security token matches a security token generated by a server computing device.
