Baby talk, also referred to as caretaker speech, infant-directed speech (IDS) or child-directed speech (CDS) and informally as "motherese", "parentese", "mommy talk", or "daddy talk" is a nonstandard form of speech used by adults in talking to toddlers and infants.
It is usually delivered with a "cooing" pattern of intonation different from that of normal adult speech: high in pitch, with many pitch variations that are more pronounced than those of normal speech. It frequently displays hyperarticulation, a measure of clear speech defined by having large amounts of acoustic space between vowels. Baby talk is also characterized by the shortening and simplifying of words. Baby talk is similar to what is used by people when talking to their pets (pet-directed speech), and between adults as a form of affection, intimacy, bullying or condescension.
