I have recently retired from 30 years as a social worker in child protection. I have always been complimented on the richness and resonance of my voice. My co-workers always looked forward to hearing me speak over the office PA system.
I have always wanted to do voice overs and now I have the time to devote to this.
I can use some supplemental income, but it is really the thrill of doing voice over that pulls me in this direction.
