Which stage involves infants controlling the pitches of their voice to make squeals and growls and ends with the ability to produce consonant-vowel sounds?

• A. Pre-speech stage
• B. Babbling stage
• C. Two-word stage
• D. Later Multiword Stage

Answer: (B)

The situation describes early phonological development where an infant begins to gain control of the voice, using pitch to make sounds like squeals and growls, and then starts producing consonant-vowel combinations. This progression—vocal play with varied pitch followed by the emergence of syllables like “ba” or “da”—is the babbling stage. Before this stage, babies mainly cry or coo, with simple vowel-like sounds. The two-word stage and later multiword stage occur much later, as children start combining words to form phrases and sentences.
