What's it like to talk like a child?

I can't hear my own voice. Many people say I sound like a child. I hate it, too. In the past, many malicious people in school would say that my voice was fake, but my classmates found out that I had always been like this and tried to change it. Some people will like to think that your voice sounds good, but some people will think that you are faking it. Fortunately, after I went to college, no one called me baby sounds, but my voice was beautiful.
