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.
Creating Lasting Memories by the Sea: A Heartfelt Journey with Our Beloved Dog Before She Crosses the Rainbow Bridge
In the face of unimaginable challenges, Noah’s story is a testament to the power of love and compassion. This brave soul, plagued by tumors and critical health conditions, was once a forsaken street dog.
But thanks to the incredible efforts of Laika, a charity based in Culiacán, Sinaloa, Mexico, Noah found herself surrounded by love in her final months. When Noah was rescued, she could barely walk due to her overgrown nails and was covered in tumors. The Fundación Laika Protectora de Animales, A.C. rescued her from a life of isolation, neglect, and pain.
Despite her terminal condition, Noah was promised happiness, love, and companionship. She watched the sunset, felt the cool sea breeze, and experienced the kindness of people who cared for her.
Noah’s journey came to an end, but not without leaving a lasting impact on those who knew her. Her courage and resilience inspired all who crossed her path. We bid her farewell with love and gratitude for the valuable lessons she taught us about compassion and the enduring spirit of animals.
Let Noah’s story be a reminder that even in the face of adversity, love can transform lives.
