A scholar has developed a method of acoustic detection, based on artificial intelligence, to identify the vocalizations of these primates among the thousand sounds of the African forest. To understand how many they are and protect them.
Listen to the sound above: you will hear a characteristic vocalization of the chimpanzees, called pant-hoot. We humans seem to scream in the forest, but for chimpanzees this sound recall is a way of communicating on long distances. “It has various ecological and social functions, including the coordination of movements, the identification of members of the group, the demonstration of dominance, the reporting of resources or the” marking “the space on the border between its territory and that of another Group “, says Adrienne Chitayat, of the University of Amsterdam, who for years has been following the chimpanzees in the Mahale Monti National Park, in Tanzania.
The census. He has just finished a census of the population and the density of the chimpanzees in the park: knowing where they are concentrated, for example, gives indications to protect some habitats rich in resources for them in particular.
Automatic listening. Chitayat also demonstrated the operation of an acoustic detection system based on artificial intelligence, which analyzes the sounds recorded in the African forest (listen to some examples of the noises produced by animals and the environment) and identifies the “panties in it Hoot “of the chimpanzees.
In this way, the presence and number of these animals can be determined in a simple and automatic way. “The goal is to increase the efficiency of passive acoustic monitoring,” explains Chitayat again. “The technique of recording the sounds of the environment is increasingly popular to study wildlife and for conservation, because it is a non -invasive method that can collect data continuously. As you can imagine, analyze such a mole Data is not practical, so artificial intelligence comes to help: the method I developed automatically analyzes recordings and identifies the calls of chimpanzees with background noise “. At the Adrienne Chitayat study we dedicate an in -depth analysis on Evidence Network n ° 389.
