Summary: A recent study reveals that dogs can learn commands by normally slowing down their speech when they converse with humans. Researchers examined the discourse levels and mental reactions of 30 dogs and 27 people across five languages to determine that humans speak to their pets at three syllables per minute, compared to four syllables when talking to other humans.
The study also revealed that dogs ‘ brains process words more slowly than humans ‘ delta rhythms, which are slower. These findings suggest that changing the intensity of your dog’s statement can help with interaction between humans and their animals.
Important Facts:
- When talking to dogs, people delayed their discourse from four to three syllables per minute.
- Dogs ‘ brains process talk at slower terminal rhythms, unlike humans ‘ faster theta rhythms.
- Dogs must understand human speech as well as its phonetic.

People speak to their dogs in a different way than just by their large pet eyes. Humans delayed their own conversation when talking to their puppies, and this slower intensity matches their dogs ‘ sympathetic capabilities, allowing the dogs to better understand their commands, according to a research published October 1st , in the open-access journal , PLOS Biology , by Eloïse Déaux of the University of Geneva in Switzerland and colleagues.
Dogs can communicate with humans, even though they themselves don’t make people sounds.
To better understand how people and dogs talk, the researchers analyzed the vocal sound of 30 puppies. Additionally, 22 individuals from those five cultures who communicate with dogs and 27 people from those five languages who communicate with other people were analyzed.
The researchers also examined the brains of dogs and humans by using electroencephalography ( EEG ) to measure their speech responses.
Humans are little faster’ talkers’ than dogs, the investigation showed, with a statement rate of about four syllables per minute, while dogs wood, growl, fabric, and whine at a rate of about two vocalizations per second.
Humans slowed their discourse rate by about three syllables per minute when talking to puppies. Ultrasound signals from dogs and cats revealed that dogs ‘ neural reactions to speech are focused on delta patterns, whereas people are focused on faster theta patterns.
The authors speculate that speaking to animals may have slowed down our speech, which may have ultimately helped us learn more about their voices because humans and dogs have different vocal processing systems.
Contrary to popular belief, dogs need both content and prosody to understand it, according to the authors,” What’s even more interesting is that while they process speech at a slow rate, they also need both prosody and slow rhythm to process it.”

” Dog–human vocal interactions match dogs ‘ sensory-motor tuning” by Eloïse C. Déaux et al. PLOS Biology
Abstract
Dog–human vocal interactions match dogs ‘ sensory-motor tuning
The best way to produce and perceive vocal and auditory systems within species is that the two likely coevolved into a crucial temporal acoustic structure.
Dogs ca n’t produce articulated sounds, but they do so when they respond to speech, which raises the question of whether this heterospecific receptive ability is influenced by speech exposure or is still limited by their own sensorimotor capacity.
Using acoustic analyses of dog vocalisations, we show that their main production rhythm is slower than the dominant ( syllabic ) speech rate, and that human–dog-directed speech falls halfway in between.
Comparative analysis of neural (electroencephalography ) and behavioural responses to speech reveals that dogs ‘ comprehension depends on a slower speech rhythm tracking ( delta ) than humans ‘ ( theta ), despite dogs ‘ equally sensitive to speech content and prosody.
In order to improve communication efficacy, we hypothesize that humans may adjust their speech rate to this shared temporal channel in order to improve dog audio-motor tuning.
