Dogs’ brains are sensitive to the familiar high-pitched “cute” voice tone that adult humans, especially women, use to talk to babies, according to a new study.
The research, published recently in the journal Communications Biology, found “exciting similarities” between infant and dog brains during the processing of speech with such a high-pitched tone feature.
Humans tend to speak with a specific speech style characterised by exaggerated prosody, or patterns of stress and intonation in a language, when communicating with individuals having limited language competence.
Such speech has previously been found to be very important for the healthy cognitive, social and language development of children, who are also tuned to such a high-pitched voice.
But researchers, including those from the Eötvös Loránd University in Hungary, hoped to assess whether dog brains are also sensitive to this way of communication.
In the study, conscious family dogs were made to listen to dog, infant and adult-directed speech recorded from 12 women and men in real-life interactions.
As the dogs listened, their brain activities were measured using a functional magnetic resonance imaging (fMRI) scan.
The study found the sound-processing regions of the dogs’ brains responded more to dog- and infant-directed than adult-directed speech.
This marked the first neurological evidence that dog brains are tuned to speech directed specifically at them.
“Studying how dog brains process dog-directed speech is exciting, because it can help us understand how exaggerated prosody contributes to efficient speech processing in a nonhuman species skilled at relying on different speech cues,” explained Anna Gergely, co-first author of the study.
Scientists also found dog- and infant-directed speech sensitivity of dog brains was more pronounced when the speakers were women, and was affected by voice pitch and its variation.
These findings suggest the way we speak to dogs matters, and that their brain is specifically sensitive to the higher-pitched voice tone typical to the female voice.
“Remarkably, the voice tone patterns characterizing women’s dog-directed speech are not typically used in dog-dog communication – our results may thus serve evidence for a neural preference that dogs developed during their domestication,” said Anna Gábor, co-first author of the study.
“Dog brains’ increased sensitivity to dog-directed speech spoken by women specifically may be due to the fact that women more often speak to dogs with exaggerated prosody than men,” Dr Gabor said.
Desperate Puppy Trapped in Slaughterhouse, Pleading for Help with Heartbreaking Eyes
Meet Toby! This story began with a heartbreaking photograph that broke our hearts. Toby was bound and wrapped in a bag, his eyes filled with terror and misery. His life was hanging by a thread, with the fear of execution just minutes away. We realised we needed to move quickly.
We rushed Toby to the vet since his condition was critical. Toby’s ordeal had rendered him paralysed, a defence mechanism, a desperate attempt to protect himself from the horrors of the world. He had clearly lost trust in humanity, and his initial check found no broken bones. The idea of crushed nerves was investigated, but one thing was certain: Toby had suffered greatly.
Toby was extremely resilient despite his pain and terror. He never complained, silently suffering the trials that life had placed upon him. Toby, like any other dog, deserved a chance at a normal existence, in our opinion.
The road to recovery began with acupuncture, and Toby surprised us by being unusually calm and cooperative. The tiny angel gradually began to trust us, and his true beautiful nature began to come through.
Today, Toby exudes happiness. While his walk remains difficult, his eyes tell a different story – one of joy, resilience, and unexpected optimism. His left leg has steadily grown stronger, allowing him to lift his body and take the first steps towards a brighter future.
Many people have been following Toby’s growth, and one generous woman gave him a wheelchair. It was an exciting time for Toby as he relished his newfound freedom. He now runs everywhere, a testament to his tenacity.
But Toby’s adventure does not end there. He continues to undergo acupuncture treatments and benefits from swimming therapy. Every day, he lives a life full of happiness, love, and caring.
It’s hard to believe that just four months ago, Toby’s life was in jeopardy. He might not have lived to see this day if fate had been one minute later. Toby’s story is a testament to the power of kindness, resilience, and second chances. He is a living reminder that every being is deserving of love, care, and the chance to live a life of happiness and purpose. Toby, you genuinely deserve all of the world’s love.
