Dog-directed speech is more effective with puppies

 A small team of researchers from the U.S., the U.K. and France has found that puppies are more receptive to dog-directed speech than are adult dogs.
In their paper published in the journal Proceedings of the Royal Society B, the researchers describe experiments they conducted recording human voices and playing them back to dogs, what they found, and what it might mean for human communications.

Most everyone has heard dog-directed speech, which is similar to speech patterns some use when talking to infants—the voice gets higher, the words come out slower and there is a sort of sing-song phrasing.  (i.e. baby talk) Some of the phrases are familiar as well, such as “Who’s a good boy?” In this new effort, the researchers looked into the use of dog-directed speech seeking to learn if there might be any modulating factors in its use.

The experiments consisted of asking 30 female human volunteers to look at pictures of dogs while reading a script consisting of typical dog-directed speech phrases into a microphone to make recordings. The recordings were then played to 10 puppies and 10 adult dogs at an animal shelter as the researchers watched and recorded their reactions.

The researchers report that the volunteers tended to raise their voices in ways similar to people speaking to human infants regardless of the age of the dog they were looking at, though it was noted that the voices were raised slightly higher for puppies than for adult dogs. They also report that at the animal shelter, the puppies responded very clearly to the voices coming from the speakers, acting as if they wanted to play. The adult dogs, on the other hand, after a quick investigation, ignored the recordings altogether.

The researchers were not able to explain why the humans spoke in dog-directed speech or why the puppies responded to it while the adult dogs did not, but suggest that humans likely respond to puppies in much the same way they respond to babies—and babies have been shown to respond more to baby-directed speech. As for why the older dogs were not interested, it might have been the case that they were simply older and wiser—they could see very clearly there was no human present speaking to them, so they chose to ignore whatever was being said.

  1. Yeah the mommy voice works the best

  2. I volunteer at a kennels and question the results as dogs also respond to singers in a similar manner…Guns and roses loses out to Michael Jackson as an example. The dogs settle down when mh sings a ballad..shes out of my life seems to settle them down

    • Hi Maria, I think researchers classify language (spoken words) and music as two different things. I use music in my canine massage practice for relaxation. The cadence of certain types of music seems to determine which pieces are relaxing to the dogs. Thanks for reading my blog!
