What's best for me? Private coaching or group courses?
Private coaching is the gold standard of dialect work. You get individual guidance, teaching geared to your own learning style, and personalized suggestions for improvement.
Group coaching offers many of the above benefits. Online courses are capped at 4 participants (in person courses are capped at 8-10 participants), and you get approximately 30 minutes of individual attention. You learn from other participants, as well as getting your own feedback, and you get to network with others who may be in a similar position to you. Furthermore, you get a chance to play around with pretending to actually be American through improv, storytelling, and games.
However you like to learn best, Barbara will do her best to help you gain an authentic American sound.
