When talking to babies, humans slow down their speech, raise their pitch and change the “color” of their voice. This ‘baby talk,’ as people know it, increases the infant’s attention and facilitates language learning. Among animals, mothers often engage in pup-directed vocalizations too, but does this also imply voice changes? A team of scientists that included Smithsonian Tropical Research Institute (STRI) researchers explored whether infant-directed communication in bats resulted in vocalization changes.
