The developed technology of Sound Intelligence, capable of automatic aggressive scream detection, was challenged by two fanatic quiz candidates and Dutch known personalities Henk Westbroek and Juliëtte de Wijn, also known as Cora van Mora (Dutch TV commercials).

After a successful demonstration, at which the system was triggered by yelling yet did not respond to the subsequent cheering, the system was further clarified: “How can the system detect aggression a voice? Is it, when someone is aggressive, due to a higher voice tone, lower voice tone or increased loudness?”

Apparently the candidates understood the system, as both gave the correct answer: Higher voice tone!
