About the Transatlantic accent
The Mid-Atlantic accent is a practiced dialect of English. Voquent, as a voice actor agency with a worldwide reach, offers the best. It blends the British RP accent with standard American English. The accent is most associated with Hollywood's early days, taught in private schools and drama schools to the American upper classes.
The use of the accent fell after WW2, and nowadays, the accent generally describes a voice that has spent equal time in American and in the UK, i.e. an English speaker that's 'difficult to place'.
