If you have a childish voice or talk from your nose , how do you make it seem more grown up?

Question

Like I want to sound more grown up. But not with my vocabulary

Answer 1

Try to lower the tone of your voice by opening up your throat, especially when calling out to someone. Lower tones carry farther with less volume and have more authority. You can exercise them by practicing singing low or drinking hot tea to help relax your vocal chords. Also practice breathing from the diaphram, like singers. Heck, you could even take a basic singing class to learn techniques to control your voice.

Answer 2

I have the same issue and I work as a manager (I'm a little woman) with a crew of all men. Try to speak from the pit of your belly; grab up a lot of air and concentrate on your stomach. I will come out deeper.
