Systems and methods may be used to detect an inaudible signal associated with a first audible signal of an audio input. The inaudible signal may include a frequency signature. The frequency signature may be associated with an electronic device type. The systems and methods may activate a response monitor. The response monitor may be activated for a predetermined time. The response monitor may be activated responsive to the frequency signature. The systems and methods may determine a content characteristic of the first audible signal based on the inaudible signal. The systems and methods may include generating a message. The message may be based on the content characteristic. The systems and methods may include transmitting the message. The message may be transmitted on a condition that a second audible signal corresponds to the message and is received within the predetermined time.
