Why do infants respond to higher-pitched voices and distinguish their mother's voice soon after birth?

Explanation:
Infants are biologically tuned to attend to higher-pitched, sing-song speech, which is easier for their developing auditory system to process and helps them pick up speech patterns more quickly. The mother's voice is the most familiar and emotionally soothing sound after birth, built from months of womb exposure plus ongoing contact, so babies quickly distinguish it from others. This combination—a natural preference for high-pitched voices and early recognition of the mother’s voice—supports bonding, regulation, and early language learning, making it the best explanation for why infants respond to higher-pitched voices and identify their mother soon after birth.
