Babbling is a stage in child language acquisition, during which an infant appears to be experimenting with uttering articulate sounds, but does not yet produce any recognizable words. It is a natural part of the language learning process in infants, rather than a way adults modify their speech to communicate with babies, which is what "baby talk" refers to. "Motherese," "infant-directed speech," and "parentese" are all terms used to describe the simplified and often higher-pitched way that adults speak to babies.
