A new study by researchers at the Faculty of Animal Behavior at Eötvös Loránd University (ELTE) in Hungary reveals that dogs can recognize their owners by voice alone and utilize some of the same voice characteristics as humans. ..The study is published at Animal recognition..
Indeed, our dog is aware of us. But when neither vision nor vision is possible, are they possible? odor By using only the voice, as it is there to guide them? If so, what is it about the voices that help them?
To find out, researchers from the Hungarian Faculty of Ethology invited 28 pairs of pet dogs and dogs to hide-and-seek in the lab. The dog had to find an owner behind one of the two hiding places while a stranger was hiding behind the other. They played the owner’s voice from the owner’s hiding place and the voice of a stranger from other hiding places, both reading the recipe in a neutral tone. The dog’s job was to choose from a distance and find an owner. The game has multiple rounds, and the owner’s voice is paired with 14 different stranger’s voices, some similar to the owner’s voice and others different.
Dogs found their owners in 82% of cases. To make sure the smell doesn’t help the dog here, in the last two rounds, researchers screamed the owner from a stranger’s hiding place, and the dog still sniffed their nose in this job. I went to a voice indicating that I didn’t use it.
Researchers also investigated exactly what helped the dog choose in his voice. “People mainly utilize pitch (higher or lower), noise (cleaner or more severe), and three properties. Tone To distinguish others (bright or dark). Dogs can take advantage of the same voice characteristics or different ones. If the two voices are different because of the characteristics that are important to the dog, the decision should be easier, “explains Anna Gabor, the lead author of the study.
The time the dog looked in the direction of the owner’s voice while waiting for the sign to disappear showed how confident they were in their decision.If the voice of the owner and the stranger are different pitch Noisyness helped dogs recognize their owner’s voice, but timbre and other sonic characteristics did not.
“This is the first demonstration that a dog can distinguish its owner’s voice from many others. This study is also dog Use some, but only some of the same voice “Characteristics that humans do to recognize who is speaking,” concludes Andics Attila, the leader in neuroethics at the Communication Lab where this study was conducted.
