I can't say exactly where they're from, but in addition to coaching Anil Kapoor, I coached several actors from around the world in international accents for several episodes of 24.
The other source of authenticity is the variety of dialects spoken by the cast. Kudos to dialect coach Joel Goldes for magnificent work. -- Talkin' Broadway reviewing Come From Away
I can't say exactly where they're from, but in addition to coaching Anil Kapoor, I coached several actors from around the world in international accents for several episodes of 24.
My past acting and directing experience uniquely qualifies me as a dialect coach: not only can I guide you in the subtleties of a new accent, I can also help you explore sound possibilities within the character's given circumstances.
I look forward to working with you.
