The perception of how voices sound can be subjective and influenced by various factors, including cultural norms and personal experiences. However, it is not accurate to claim that men with high-pitched voices sound like children while women with low-pitched voices don't sound like babies.
Voice pitch does play a role in how we perceive someone's age or gender, but it is just one aspect among several that contribute to our overall perception of vocal characteristics. Many other factors, such as resonance, intonation, vocal quality, and speech patterns, also contribute to how we perceive someone's voice.
While it is true that children, especially prepubescent boys, tend to have higher-pitched voices, associating high-pitched male voices exclusively with children is an oversimplification. There is a wide range of vocal characteristics among individuals of all genders, and vocal pitch alone cannot determine someone's age or gender accurately.
Similarly, while women with lower-pitched voices may differ from the stereotypical high-pitched "baby talk" associated with infants, it doesn't mean that they don't sound feminine or like adults. The perception of femininity and masculinity in voice is influenced by a combination of pitch, resonance, and other vocal qualities.
It's important to recognize that voice perception is a complex process influenced by multiple factors, and making broad generalizations based solely on pitch can lead to inaccurate assumptions or stereotypes. Each person's voice is unique, and it's essential to consider a variety of vocal characteristics when forming judgments about age, gender, or other aspects of someone's identity based on their voice.
