How can I make my singing voice stronger?

First performance in front of peers can cause lot of anxiety and stress. Voice , being the mirror of soul, often gets greatly influenced by your emotional condition. With practice and maybe some help from your singing teacher,friends or your family doctor, you should aim for controlling the anxiety. You could consult a Speech Pathologist ( or Speech Therapist) who can evaluate your speech and singing patterns, also tell if braces are any hindrance( very unlikely) They can graphically analyse your voice patterns and by training modify your voice or singing. They may even refer to ENT specialist who can study the fast movements of your vocal cords by Laryngo-stroboscopy to diagnose any pathology.
