Can dogs understand people speaking?

Yes, dogs can understand people’s happy and sad voices.

Scientific research shows that dogs only respond to human sound stimulation except for their own kind

In order to understand the interaction patterns between dogs and humans, researchers from Eötvös Eötvös University in Hungary conducted Try having a lab dog lie quietly in an MRI machine for at least six minutes to observe the blood activity in the dog's brain. The process was very difficult, but the dogs still showed respect to their poop-scraping officials and finally started the experiment smoothly.

After each dog lay down in the instrument, the researchers played about 200 sound stimuli of three types: dog barks, human voices, and other meaningless noises. Unexpectedly, experimental dogs not only increase their brain activity when they hear the same kind of sounds, but human voices can also excite their brains, but meaningless sounds do not.

Moreover,They can also distinguish the happy and sad emotions of human voices: happy human voices cause their brain activity to be stronger than sad human voices.

But why do dogs only respond to human sound stimulation in addition to the sound stimulation of the same kind?

The relationship between dogs and humans also starts from their first acquaintance. rise.

As early as 14,000 years ago, dogs have been human companions. Initially, humans domesticated some docile wolves and trained them to help them with daily labor and hunting.

After generations of reproduction, finally, domestic dogs appeared.

For tens of thousands of years, dogs have been accompanying humans, and humans have become their special little partners.So not only do dogs remember human voices, but they also pass on this sensitivity to sounds from generation to generation. Come down.

Why do dogs understand human voices?

Dogs’ sensitivity to human voices has evolutionary significance. They are bred by humans to better help themselves. As human companions, dogs have to try to understand the information contained in human voices. Over time, they increase their sensitivity to human voices, and their brains can automatically recognize human voices. In short, Dogs can currently only distinguish between joy and sadness in human voices
