I am using the term "voice coaching" broadly to include teaching singing, correcting diction in several languages, enhancing individual sound, encouraging self-confidence and poise, and choosing repertoire appropriate to a students personality, voice type and goals.
In academia, a singer studies voice technique with a singing teacher and then studies repertoire and language diction with a voice coach. In the private sector where I teach, the need is much more inclusive.
The most important key to a singing students success is when a song is written or transposed to a good key, or the proper vocal range for their voice.
My school has many children and youth who desire the information to develop their singing voices correctly. Most of the adult students are professional people who are fulfilling a lifelong desire.
While offering vocalises, or exercises to aide in breath coordination and sound enhancement, I also encourage creativity and emotional expression. Students feel respected and safe in my studio environment and we spend many hours in joyful discovery of ourselves and of music.
For people seeking to improve their speaking voice, some of the same exercises used for teaching singing may apply to speech development. I am not a speech pathologist. I am only concerned in the technique of sound enhancement; why a persons voice sounds the way it does and if they desire, I help them find ways to sound more appealing. By appealing I mean, helping them find their natural sound and encouraging confidence in that sound through breath "support" and vowel "placement."
The workshop environment is fun and safe. The work can only be successful if a student practices and applies the techniques studied to their daily life.
