A South Korean startup has developed an AI-powered dog collar that can detect five emotions in canines by monitoring their barks using voice recognition technology.
The Petpuls collar can tell pet owners through a smartphone application if their dogs are happy, relaxed, anxious, angry or sad. It also tracks dogs' physical activity and rest.
The company began gathering different types of barks to analyse dogs' emotions in 2017. Three years later, they developed a proprietary algorithm based on a database of more than 10,000 samples from 50 breeds of dogs.
