Dunstan Baby Language

Dunstan Baby Language is a theory about infantile vocal reflexes as signals, in humans. The theory is that across cultures and linguistic groups there are five sounds, each with a meaning, that are used by infants before the language acquisition period. The hypothesis was developed by Australian former mezzo-soprano, Priscilla Dunstan, and has been featured on ''The Oprah Winfrey Show''. Dunstan's theory has not been scientifically validated.
