Abstract
Disclosed herein are system, method, and computer program product embodiments for authentication of users of electronic devices by voice biometrics. An embodiment operates by comparing a power spectrum and/or an amplitude spectrum within a frequency range of an audio signal to a criterion, and determining that the audio signal is one of a live audio signal or a playback audio signal based on the comparison.
