A server device transmits a call to a user device; receives a signal in response to the call; receives speech when the call is answered; performs an operation to determine a signal factor and another signal factor based on a signal duration; performs another operation to determine a speech factor and another speech factor based on a speech duration; determines whether the speech contains key words; performs an action to determine a confidence factor and another confidence factor based on the speech; computes a factor based on the signal factor, the speech factor, and the confidence factor; computes another factor based on the other signal factor, the other speech factor, and the other confidence factor; determines that the party is the user device when the total factor is less than the other total factor; and outputs a non-interactive message based on the determination that the party is the user device.
