US Patent 7460998 Voice connection system between humans and animals

A voice connection system comprises a sensor matrix sending to a control unit signals indicating an animal's status in terms of stimuli, feelings, events, actions or behavior of said animal. The control unit selects—depending on the signals received—a voice message recorded into memory means associated to the unit, and activates a loudspeaker belonging to the system, in order to issue said voice message. The system further comprises voice recognition means, which activate pulse generators depending on the content of a voice message uttered by the human user.
