Method and system for identifying a party answering a telephone call based on simultaneous activity
First Claim
1. A method for detecting whether an automated device is currently providing audio on a telephone call, the method comprising:
- outputting an audio signal to the telephone call;
inputting an audio signal from the telephone call;
determining an amount of time during which the input audio signal and output audio signal are both active; and
when the determined amount exceeds a threshold amount, indicating that an automated device is providing the audio.

Abstract
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.

17. An automated method for detecting whether a recorded voice or a live voice is currently providing audio of a telephone call, the method comprising:
-
outputting an audio signal to the telephone call;
inputting an audio signal from the telephone call; and
determining whether a recorded voice or a live voice is providing the audio of the telephone call based on amount of overlap of sound on the output audio signal and input audio signal. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34)

35. A system for identifying a party answering a telephone call, comprising:
-
a telephone line having an input line and an output line;
a first component that monitors the input line to detect when the telephone call has been answered and, when answered, outputs an audio signal to the output line; and
a second component that monitors the input line to determine when sound is simultaneously being input on the input line and output on the output line, the amount of simultaneity indicating whether a person or an automated device has answered the telephone call. - View Dependent Claims (36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46)
