A recent study has found that female bottlenose dolphins change their tone when addressing their calves, using a high-pitched “baby talk” similar to humans. The researchers recorded the signature whistles of 19 mother dolphins in Florida and found that when directing the signal to their calves, the mother’s whistle pitch is higher and her pitch range is greater than usual. This behavior may help offspring learn to pronounce novel sounds and catch their attention. The study provides unprecedented data on dolphin communication and further research is needed to understand if dolphins use baby talk in other contexts.
