A method and system for identifying whether a communicating party is a
person or an automated device is provided. The identification system
determines whether a person or an automated device is currently providing
audio of the communication. When the identification is to be determined,
the identification system outputs an audio signal to the party. The
identification system monitors the input audio signal from the party to
determine whether a person or an automated device is providing the input
audio. The identification system makes this determination based on
whether there is simultaneous sound on the input audio signal and the
output audio signal. The greater the amount of simultaneous sound, the
greater the likelihood that the party is an automated device.
