Which form of speech used with infants exaggerates pitch, rhythm, and dynamics?

• A. Infant-directed speech
• B. Normal adult speech
• C. Monotone speech
• D. Whispered speech

Answer: (A)

Infant-directed speech uses exaggerated prosody—higher pitch, a wider pitch range, slower tempo, and stronger dynamics—to capture infants’ attention and aid language learning. This distinctive way of speaking helps babies notice important cues in language, such as where syllables or word boundaries occur, and makes emotional and social signals clearer. Across cultures, caregivers naturally adjust their voice in this way when talking to babies, which supports both attention and early word learning.

Normal adult speech tends to be more at a natural pitch and pace, without the exaggerated rise and fall that draws infant attention. Monotone speech lacks varied dynamics, making it harder for babies to engage with the speech stream. Whispered speech lacks the tonal cues and energy that help infants discern rhythm and intonation. So the form that best fits the idea of exaggerating pitch, rhythm, and dynamics with infants is infant-directed speech.
