This article talked about how adults talk to babies and why we do it. When we talk to babies, we tend to raise our pitch a little and supposedly, it calms the baby down. They also talked about a research project where they recorded adults from different parts of the world, and noticed that those who come from western places raised their pitch the most, and in remote places didn't raise their pitch that much but everyone raised their pitch at least a little. The way we talk to babies is universal and we've evolved as humans to be able to communicate with infants.

The features of baby talk - softer tone, higher pitch, almost unintelligible vocabulary - are global. Researchers at Harvard's Music Lab documented over 1,500 recordings in 21 urban, rural and Indigenous communities - making their work possibly a first of its kind experiment. The article includes samples from different languages around the world. There are many reasons why baby talk might have evolved in humans and why it might serve beneficial purposes. Some theories suggest that the way we speak accentuates the vowels of the speech and helps babies learn speech. Other theories suggest that this kind of baby talk helps regulate the baby's emotions and helps structure the social interactions we have with babies, so it helps socialize them and control their behavior and mood. In prehistoric times, having ways to interact with babies and to care for them while still being able to keep your eyes up to look out for predators and use your voice to interact with babies, might have been an important reason why we may have evolved these kinds of behaviors.
