I am 14 years old and I tend to force myself to have a lower voice. My voice isn’t extremely high pitched like a 6 year olds voice for example, but it still isn’t that deep. My friends have much deeper voices than I do and it humiliates me a bit. I want to know, will forcing myself to speak in a deep voice damage my vocal chords? Also since I am only 14 will my voice ever get deeper naturally?
Any forcing of the voice is not healthy, especially at your age. There are many factors to consider and we all mature at different rates, but your voice will continue to lower over the next few years. The best person to advise you is a doctor who can thoroughly examine you and determine if everything is normal for where you are in the process of puberty. Then a voice coach can help you open into more resonance so the voice has a complete tone and natural depth.
