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.

Brittany Hawley’s Incredible Adventure with Her Faithful Sidekick, Griffin 🐕
Let me introduce you to Brittany Hawley, a 25-year-old from North Carolina who has faced tremendous challenges due to a chronic neurological disease that confined her to a wheelchair when she was still in her teens. However, Brittany’s life changed for the better when she applied for a service dog to help her with her daily routines. That’s when she met Griffin, a golden retriever who would become her constant companion. This remarkable duo met through a special program called ‘paws4prison.’ This program trains inmates in West Virginia prisons to train highly skilled assistance dogs. When Brittany and Griffin first met, several dogs were presented to her, but Griffin stood out. Unlike some dogs that were wary of her wheelchair, Griffin jumped straight into Brittany’s lap and showed her affection.
Recently, Brittany accomplished an important goal by completing her master’s degree in occupational therapy from Clarkson University. This was a momentous occasion not only for her but also for her loyal companion, Griffin. Throughout Brittany’s years of study, Griffin played a crucial role in her life, attending classes with her, retrieving her phone, and actively participating in her community activities, social groups, and research projects. Griffin even supported her during her internship at Fort Bragg.
When the four-year-old golden retriever received his honorary diploma, it was a recognition of his “extraordinary effort, steadfast commitment, and diligent dedication to the well-being and student success” that contributed to Brittany’s achievements. Brittany proudly said, “I advocated for Griffin’s graduation from day one. He did everything I did.”
Brittany and Griffin proved to be an invaluable team for soldiers grappling with physical limitations and psycho-social issues. Griffin’s presence was so significant during therapy sessions that patients often referred to him as a co-therapist alongside Brittany. On a daily basis, Griffin helps Brittany with various physical tasks such as opening doors, turning on lights, and retrieving objects indicated by a laser pointer. However, what Brittany values the most about Griffin is his ability to comfort her during times of anxiety and depression, which has helped her manage the constant pain that she experiences. Brittany’s story demonstrates the remarkable impact that service dogs like Griffin can have, thanks to their highly specialized training that equips them to provide assistance and emotional support to individuals with disabilities, mental health conditions, and other qualifying circumstances.
Brittany’s experience with her furry friend, Griffin, is a remarkable testament to the indomitable connection that exists between people and their canine pals. This bond effortlessly overcomes obstacles and acknowledges the influence of willpower and affection. 🌟🐕
