Abstract
Systems and methods for user authentication include a microphone generating a corresponding audio input signal, and a voice processing system operable to identify a pass phrase including human speech in the audio input signal, a voice authentication system operable to extract feature characteristics associated with the identified pass phrase, compare the extracted feature characteristics to user voice features, and determine a confidence level of a voice match. The voice authentication system receives a first acoustic code, compares the first acoustic code to a second acoustic code associated with the user, and determines whether the first acoustic code and second acoustic code match. A user is authenticated if the first acoustic code and second acoustic code match and the confidence level exceeds a threshold value. A user device is operable to prompt the user to speak the pass phrase, generate the acoustic code and output the acoustic code through a speaker.
