This is to say that all types of voices are working and making money. Casting agents sometimes use voices that just sound like the"person next door" who is "unpolished" because it sounds more sincere to them. Other times a more polished voice IS needed. There are many ways of looking at casting and voiceover success and there is no one right way. This doesn't mean you shouldn't practice and have good skills for reading copy so you can take direction. The meaning is don't let anything stop you. Develop your skills, concentrate on what your unique personality brings to the table and FOCUS!!!
It is simply one of the most wonderfully ways to make a living for people who love to talk:)
