* Other Factors: Voice changes can also be influenced by factors like genetics, lifestyle, and vocal training.
It's important to respect their privacy and avoid speculating about their personal health choices.
Remember, focusing on physical changes like voice depth isn't a healthy way to judge or compare individuals. Everyone develops differently, and their personal choices should be respected.
