SYSTEMS AND METHODS TO DETERMINE THAT A SPEAKER IS HUMAN USING A SIGNAL TO THE SPEAKER

Abstract:

A system and method of voice authentication of an audio stream represented to be the spoken voice of a person, may include receiving via a device such as telephony device a voice stream or voice recording represented to be that of a person speaking, providing an interfering or interrupting audio signal to the device, and using information regarding the interfering audio signal, determining if the voice stream indicates a reaction to the audio output. In such a manner it may be determined if the spoken voice is that of a real, live, person, speaking in real-time, or that of a device or person attempting to imitate a person (e.g. using a recording).
