Dogs understand both vocabulary and intonation of human speech

Dogs have the ability to distinguish vocabulary words and the intonation of human speech through brain regions similar to those that humans use, a new study reports.

Researcher Attila Andics note that dogs vocabulary learning is a “more ancient function that can be exploited to link arbitrary sound sequences to meanings.”

Words are hardly ever found in nonhuman vocal communications. Intonation is another way that information is conveyed through speech, where, for example, praises tend to be conveyed with higher and more varying pitch. Humans understand speech through both vocabulary and intonation.

Andics and colleagues explored whether dogs also depend on both mechanisms. Dogs were exposed to recordings of their trainers’ voices as the trainers spoke to them using multiple combinations of vocabulary and intonation, in both praising and neutral ways. For example, trainers spoke praise words with a praising intonation, praise words with a neutral intonation, neutral words with a praising intonation, and neutral words with neutral intonation.

Researchers used fMRI to analyze the dogs’ brain activity as the animals listened to each combination. Their results reveal that, regardless of intonation, dogs process vocabulary, recognizing each word as distinct, and further, that they do so in a way similar to humans, using the left hemisphere of the brain.

Also like humans, dogs process intonation separately from vocabulary, in auditory regions in the right hemisphere of the brain. Also like humans, the researches found that the dogs relied on both word meaning and intonation when processing the reward value of utterances.

Thus, dogs seem to understand both human words and intonation. The authors note that it is possible that selective forces during domestication could have supported the emergence of the brain structure underlying this capability in dogs, but, such rapid evolution of speech-related hemispheric asymmetries is unlikely. Humans, they say, are only unique in their ability to invent words.
