Can dogs understand human speech? Yes, dogs can understand the happy and sad sounds of humans. Scientific research has shown that dogs only respond to human voice stimuli in addition to their own kind Researchers at the University of Roland, Hungary, tried to understand the interaction patterns between dogs and humans by having the experimental dogs lie quietly in an MRI machine for at least six minutes to observe the blood activity in their brains. The process was difficult, but the dogs did their own pooper scooper a favor and the experiment started smoothly. The researchers played about 200 sound stimuli, three types: barking dogs, human voices, and other meaningless noises, after each dog was laid into the apparatus. To my surprise, not only did the experimental dogs’ brain activity increase when they heard similar sounds, but human voices also excited their brains, but meaningless sounds did not. Moreover, they were able to identify the happy and sad emotions of human voices: happy human voices made their brains more active than sad human voices.
But why would dogs respond to human vocal stimuli in addition to those of their own kind? The relationship between dogs and humans begins with their first acquaintance. As early as 14,000 years ago, dogs were already human partners. Initially, humans domesticated some docile wolves and trained them to help themselves in some daily work and hunting. After generations of breeding, eventually, domestic dogs emerged. Why Dogs Understand Human Voices Dogs’ sensitivity to human voices is evolutionary. They were bred by humans, and in order to better help their human buddies, dogs had to try to understand the information contained in human voices. In the long run, they improve their sensitivity to human voices and their brains can automate the recognition of human voices. In short, dogs can currently only distinguish the likes and dislikes of human voices
