How old do you have to be to addition for the voice?
Old enough to know how to spell "audition".
16? or maybe 18
Audition? Get in line for 3 years,for a chance to be on a show for 1 minute,that will be off the air before you finish tryouts.
old enough to know that you audition, not do arithmetic for your voice. (just kidding) but i'd bet that as long as you're old enough to work in your state, you're old enough to audition for voice work. good luck.
