The utterance or hearing of incoherent speech sounds. It is thought that the Greeks heard all other languages as 'babble', giving the word an onomatopoeic origin. Indeed unfamiliar languages do sound formless, with no clear demarcation between words. In a familiar language, word units are identified not by breaks in speech but from the continuous 'babble' of speech, much as separate objects are seen from the mosaic pattern of stimulation of the eyes.
It is believed that babies produce all the speech sounds of any language in their babbling, and that speech sounds or phonemes of the language of their environment are gradually selected, according to use (see
language development in children).
