My voiceover career started in my 20's when a teacher noticed that I had a great reading voice and asked me to record some stories for her class to play while she graded papers. They were a hit and she recommended me to others.
I am a classically trained singer and have spent many years singing in choir.
At my workplace I have been asked to record IVR, trainings, presentations etc.. and have done so with positive feedback.
In high school I did Lunchtime Shakespeare and received the compliment that when I speak in William's tongue, its the first time they've ever understood Shakespeare.
I am an accountant with a business degree. Voice overs are just a side "business" I've fallen into when people hear me over the phone, they want me to record for them. In high school and college, I studied acting and music, but have not had any formal training since then unless you count Toastmasters.
