Caregiver speech refers to the simplified and repetitive type of speech used by adults when speaking to infants and babies. It is characterized by slower speech, higher pitch, exaggerated intonation, shorter utterances, and simpler sentence structures. Caregiver speech helps infants learn language sounds and begin to recognize, then comprehend words. As children develop, their parents' speech becomes less repetitious with longer, more complex sentences about topics relevant to the child's everyday experiences and interests. While language development is primarily driven from within, caregiver speech offers support and guidance along the way.
