Scientists enlist AI to interpret meaning of barks

They are also digging into whether AI can tell a dog's age, gender and breed based on the noises it makes.

Researchers from the University of Michigan are using artificial intelligence (AI) to better understand what a dog's bark conveys about whether it is feeling playful or angry. The scientists were able to make progress towards decoding canine communication by repurposing existing computer models trained on human speech. They the fed them into a machine-learning model - a type of algorithm that identifies patterns in large data sets - which had been designed to analyse human speech.
