You have an accent.
No matter what anyone has said to you in the past, I am here to set the record straight. You have an accent. I have an accent. Everybody who speaks (and even everyone who signs) has an accent. Every person, everywhere on the planet has an accent (also referred to as a dialect), we just don’t take much notice of the ones that are very similar to our own.
If every person has an accent, it follows that every character in every commercial, every film, every TV show, every web series and every play also has an accent.
How much have you been relying on your own personal everyday accent to fit every role?
How many more roles would you be eligible for if you took the time and did the work to really master a few strategically chosen dialects?
How many more jobs might you book?
