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.
“From Broken to Resilient: The Inspiring Journey of a Homeless Canine’s Healing and Redemption”.
“Unfolding the Chronicles with a Homeless Dog, a Trembling Soul Navigating the Harsh Realities of Life on the Streets. His spirit was broken, and his heart bore the invisible scars of abandonment and neglect. Fear had become his constant companion, and he sought refuge in the shadows of a world that had shown him little kindness.
But amidst the indifference of the world, there were those who saw the urgency of his situation. Compassionate individuals, driven by empathy and a deep love for animals, recognized the urgency of his plight. Their hearts ached at the sight of a dog so scarred and broken, and they endeavored to offer him a lifeline of hope.
The road to healing was a delicate mission, marked by patience and gentleness. The scarred homeless dog, initially wary and fearful of human contact, was approached with utmost care. It took time, but slowly, trust began to form between the dog and his newfound caretakers. Commissioned by passion and genuine concern, they worked tirelessly to offer him a lifeline of hope.
The journey to healing was a turbulent path, a trial by fire to transform the broken spirit. He was gradually coaxed away from the shadows that had been his refuge, and his heart began to thaw in the embrace of love and reassurance. With each passing day, his fear gave way to trust, and his wounded soul found solace in the silent gestures of compassion.
The pivotal moment of rescue was a triumphant point in the dog’s life. He was gently coaxed away from the haunting memories of his rough background, and he found himself enveloped in an atmosphere of care and belonging. With each passing day, his fear transformed into courage, and he began to blossom in the warmth of genuine affection and understanding.
The dog’s journey from a place of darkness to the embrace of light is a poignant reminder of the capacity for compassion and intervention, even in the face of overwhelming fear and despair. The scarred homeless dog, once abandoned and broken, became a beacon of resilience and hope.
This tale is a testament to the power of resilience in the face of adversity, a celebration of the indomitable spirit that, despite all odds, strives for love and redemption. It stands as a reminder that, even in the darkest corners of life, there is always room for a brighter tomorrow, fueled by love, compassion, and the unyielding spirit to overcome.”
